As of 1st July 2012 I’ve merged the corrections and the discussion on the various options from here into the previous post to keep it all in one place. The big change is that the recent buff to Mindbender with Build 15799 (1.0% per swing -> 1.3%) it’s a stronger choice now and competitive with the others, although still probably not an automatic go-to since PW:Solace and FD,CL have greater potential.

FD,CL Procs and Regen

In my initial comparison of FD,CL procs I chose to simply treat them as occurring on 15% of casts, and thus attributing 15% of the mana saving (19,500 mana) to each eligible heal.

That’s fine in spreadsheets and for simplifying the analysis, but how can we quantify the randomness? One way is to simulate a lot of encounters and see what sort of range we might expect.

Considering a 5-minute fight, and two usage scenarios, here’s what I get from an arbitrary run of the sim (10,000 iterations):

1. Bare minimum – 2 casts per minute – Mean saving per fight: 29,253 mana – StdDev: 22,456 mana.
2. Tank-healing heavy – 20 casts per minute – Mean saving per fight: 295,563 mana – StdDev: 70,406 mana.

The standard deviation (StdDev) is a measure of the size of the variation from the average, and that’s the important figure here. The more statistically-minded will already have drawn their own conclusions, but for the rest of us the short version is this:
If you’re casting FD,CL-eligible heals infrequently you might get lucky and nearly double your returns but you’re just as likely to end up with practically nothing. If you cast frequently you’re better off, but you could still end up losing out on a quarter of the returns you were expecting.

Obviously over a longer fight the numbers will even out a little better, but the majority of the fights do fall into the ~5-6 minute range, at least in Cataclysm.

The point of all this is that because of the huge variations of FD,CL’s procs you really need to be casting a lot of eligible heals to be sure of getting the benefit. When comparing PW:Solace and FD,CL, you should underestimate the value of FD,CL, particularly if running out of mana is likely to be a killer rather than an inconvenience. PW:Solace gives you flexibility that FD,CL does not.

Again, this doesn’t change the conclusion that PW:Solace is better for raid healing and FD,CL only if you’re tank- or single-target-healing a lot, but it does shine light on the massive unreliability you can expect to see in FD,CL returns.

Updated 24th June, see the follow-up post for details.
Updated again 1st July, to take account of the 1.0% -> 1.3% bump in Mindbender’s mana return. This changes the conclusions a little: originally Mindbender was barely an advantage over Shadowfiend, now it is a viable option.

For another take on this, Derevka at Tales of a Priest has carried out a similar analysis including presenting the data in some slightly different ways. That’s well worth a read as well; more eyes and more opinions are of course always a good thing for the community, as are different ways of explaining and presenting things.

It Depends

Obviously it’s going to be situational, there’s no question about that. Each of the talents has a different focus and will help in different scenarios:

• From Darkness, Comes Light – Gives you a 15% chance on casting a Smite, Heal, Flash Heal, Binding Heal or Greater Heal to get a free, instant-cast Flash Heal. You can store up to 2 free heals.
• Mindbender – Replaces Shadowfiend with a Mindbender. With Mindbender you get 1.3% Mana per swing instead of 3%, but a 1 minute CD instead of 3 minutes. You also get an extra two swings from the Mindbender because it has a 15s duration compared to the Shadowfiend’s 12s. The Mindbender’s damage is around 5.5k per swing (for me at level 88) compared to around 6.5k for the Shadowfiend.
• Power Word: Solace – New! Deals light damage to an enemy, but grants 2% of mana back per cast. Priestly Telluric Currents, if you will. (Currently this restores mana even against immune enemies or if you miss, which is convenient).

First I’ll look at Mindbender and compare it to the other two options, then discuss the comparison of FD,CL with PW:Solace. If you just want the short version, then skip to the conclusions.

Mindbender

The graphs below show the amount of mana returned for Mindbender compared to Shadowfiend for a range of fight durations from 3 to 12 minutes. Because Mindbender replaces Shadowfiend, this is the net benefit of taking the talent.

The first shows the best-case situation, where you cast Shadowfiend or Mindbender pretty much on the pull and none of the mana returned is wasted. At level 90 this is consistent with chain-casting anything but Heal. This also assumes a 15% miss chance (healers are likely to have no hit bonus, and 15% is the standard chance to miss a boss-level mob).

Mindbender and Shadowfiend mana returns for a range of fight durations (Level 90, Immediate first cast)

Under this scenario Mindbender generates additional mana, both because of the extra swings and higher mana per swing, and because of the greater granularity (so you can fit more casts in.

If you don’t need the mana in the very early stages of the fight and delay the first casts of both until you’ve opened up a suitable mana deficit, the effect is more pronounced. The second graph shows the effect if you choose to delay Shadowfiend for a minute after the pull compared with waiting 20 seconds to cast Mindbender (in both cases the delay is sufficient to let a sufficient mana deficit build up, even being fairly frugal with mana).

Mindbender and Shadowfiend mana returns for a range of fight durations (Level 90, Delayed first cast)

In this case the greater granularity of Mindbender lets you fit an extra cast in much earlier, opening up a slightly larger gap over most fight durations.

However, remember that the benefit of Mindbender is the difference between Mindbender and Shadowfiend. So the possible advantage of Mindbender over Shadowfiend needs to be weighed against the potential benefit of the other two talents.

Looking at the graphs the gap widens and narrows as the encounter duration changes. For a 12-minute fight the gap is the largest, at 162,180 mana. To compare that to the other talents, consider that PW:Solace gives 2%, or 6,000 mana, per cast. So Mindbender equivalent to 162,180/6,000= 27.03 PW:Solace casts over the course of the fight, which is 2.25 PW:Solace casts per minute over 12 minutes. So if you can squeeze in just over 2 PW:Solace casts per minute, PW:Solace beats Mindbender. Since 2 FD,CL-eligible heals are worth roughly 1 PW:Solace cast, double those figures to see how Mindbender compares to FD,CL.

Let’s look at how the gap looks over the same range of fight durations as before:

Advantage of Mindbender over Shadowfiend, expressed as PW:Solace Casts per Minute

The dotted line is where things used to be at 1%, and the solid line is the current state, including the buff to 1.3%.

While there is a lot of variation depending on the fight length, the range is generally between 1 and 3 PW:Solace casts needed to break even, and typically comes out around 2, on average.

The bottom line is this: if you can cast at least 3 PW:Solaces per minute of the fight then Mindbender is simply the weaker choice. If you’re not sure, check the chart and consider the likely fight length, and decide whether you think you can hit the target number instead.

Mindbender does have other advantages to be aware of though that could change the equation in specific cases:

1. If your Shadowfiend is likely to get killed, the Mindbender gives you more bites at the cherry. 2/3 of the mana if one Mindbender dies is better than 0/3 if you lose the Shadowfiend. But this shouldn’t be a huge problem. More importantly;
2. Mindbender is very much fire-and-forget. When the button lights up you just cast and get a nice mana income. No fuss, no bother. Usually encounters aren’t non-stop from start to finish, but if you find yourself really struggling then MB isn’t a bad option
3. The Mindbender does a lot more damage over the course of the fight. Each SF cast is good for about (depending on crits and misses etc, of course) around 50,000 damage; Each Mindbender cast also accounts for around 50,000 damage but you get 3 Mindbenders to every Shadowfiend, so you’re comparing 50,000 to 150,000. When DPS counts, Mindbender gives an advantage, albeit a small one.

FD,CL vs Power Word: Solace

Power Word: Solace

If you’re not casting single-target heals very often, the choice becomes simpler because you’re not going to see the benefits of FD,CL. But if you’re doing a bit of both, how do you decide?

Let’s get a feel for the numbers first.

• Assuming no internal cooldown, FD,CL has a 15% chance to proc from one of the named heals. We can (very roughly) say that each eligible cast you make is worth 15% of the mana cost of Flash Heal, or 2925 mana at level 90.
• PW:Solace is worth 2% of your mana per cast, or 6000 mana at level 90.

With those numbers in mind, have a look at your logs or just make an educated estimate of how many times you’re casting an eligible heal in a fight. Divide that by 2 and that’s how many PW:Solace casts you’ll need to squeeze in to come out ahead.

Remember that Evangelism procs from Penance in MoP, so if you’re heavily raid healing then you may not need to cast Smite at all. This means that FD,CL is not an automatic choice for Discipline even if we’re using Archangel liberally.

As a general rule of thumb to get started, if I were going to be primarily raid-healing I’d lean towards PW:Solace to begin with, while if I knew the tank might need more attention on a given encounter I might try FD,CL as my first pick. But the key to maximising this is actually reflecting on your healing style and the number of PW:Solace opportunities in a given encounter and making an informed decision.

Conclusions

For tank healing FD,CL looks like the strongest choice. If you’re able to cast more than 6 FD,CL-eligible heals per minute (and you should be if you’re healing the tank) then FD,CL beats Mindbender. Deciding between FD,CL and PW:Solace is trickier, but bear in mind that you need to fit in at least 1 PW:Solace for every FD,CL-eligible heal you cast. If you’re throwing a stream of Heals and Greater Heals (with PW:S, Penance, PoM and Smite/HF woven in) at your tank then you’re looking at somewhere on the order of 10 PW:Solace casts per minute to break even.

For raid healing PW:Solace should be your first choice. To guarantee to beat Mindbender you need to fit in 3 Power Word: Solace casts per minute on average, but you can often come out ahead with just 2 PW:Solaces per minute.
However, if you’re finding yourself in a ‘floater’ role and you find that you’re casting more than twice as many FD,CL-eligible heals (Heal, Greater Heal, Binding Heal, Flash Heal and Smite) PW:Solace casts, then you might see a greater benefit from picking FD,CL. I’d recommend starting off with PW:Solace and looking for as many opportunities to cast it as possible, and then checking your logs and seeing what’s most appropriate for your playstyle.
Remember that PW:Solace has the most potential if you can find and take the maximum number of opportunities and cast it as often as possible.

Mindbender is valuable for non-stop raid-healing when you aren’t going to benefit from FD,CL but also can’t squeeze in enough PW:Solace casts. Its fire-and-forget nature leaves you free to get back to what you’re doing without much thought and management.

When the Dragon Soul nerfs were first announced I wasn’t thrilled. They changed the experience when we didn’t need it changing. We were still progressing, still improving both gear-wise and skill-wise, and what we really wanted was more time.

An Anecdote

We’d spent a couple of weeks sat at heroic Spine at 10% and were consistently getting to the final lift of the fight before a healer or tank would die and the game would be over. We went away on the Sunday, had a good rethink, really sorted out a few things and were all set to go back in and kill it once and for all. Unfortunately we’ll never know if we really did have it nailed because the fight got nerfed that week; we went in the following Wednesday and 2-shot it.

That did rather take the edge off the achievement.

As did two other guilds on our realm killing it on the same night.

Levelling the Field

Sometimes a boss will come along which provides a serious challenge to a raid team. Guilds will “bunch up” at this point as they work on it, but eventually one will manage to get past it and move ahead for a while. That’s good, because it helps to space guilds out and feeds into the sense of competition. Nerfs undermine that.

Lower the bar and suddenly the leader is whoever gets organised and pulls earliest. That’s not good for competition. I don’t raid for a ranking but I do pay attention to it, and having your ranking determined by the time of the evening you raid, or whether you extended your lockout or re-cleared, or whether one of your raiders had internet problems that night just doesn’t feel right.

What’s more, often you’re not actually solving the problem but postponing it. A guild that’s stuck on heroic Hagara will just get stuck on heroic Blackhorn instead. By not allowing them the time to figure out the solutions (improve DPS, coordinate better, etc) on their own, you’re giving them the metaphorical fish, when it would be better to teach them to fish.

What Does Heroic Mean Anyway?

On my fairly small server 11 guilds have defeated heroic Madness, and 30 guilds are at least 5/8. 91 have killed at least one heroic boss. According to WowProgress almost 10% of the guilds recorded globally have killed heroic Madness. Go back to WotLK, and only 2% of guilds killed heroic Lich King on 25-man, and less than 7% on 10-man despite the gear advantage.

I know 10% is still a minority, and the raiding population is also a small fraction of the playerbase, but I can’t help feeling that the “heroic” tag has lost some of its lustre at this point.

For me, “heroic” should mean difficult to the point where less than 5% of guilds (and maybe a lot fewer than that) can defeat the final encounter. It should mean that you acquired pretty much the best gear available to you, and still had to reach deep down to get the kill. You need to bump up the skill side of the gear x skill product to pull it off. Nerfs that kick in before the gearing process is even close to complete just serve to undermine this.

A Surfeit of Healers

The new collective noun for healers: a surfeit.

Nerfs play merry hell with raid composition. We’ve dropped from needing 3 healers for most of the fights to solo-healing several of them, and at least one of us is stuck either sitting or DPSing each week. Believe me, that’s not something any of us especially enjoys.

The trouble is that nerfs don’t usually affect the number of things to be tanked, and more DPS is rarely a problem (Madness is the exception to both of those rules), so their roles are secure and relatively unchanged. But as the fights get nerfed there’s just not enough healing to go around and it directly affects our play experience and our fun level.

Incidentally, 2-healing heroic Madness last week was the most fun I’ve had in ages! Talk about running on fumes!

Solutions?

It wouldn’t be fair to grumble and mutter without at least trying to be constructive.

First off I can accept the argument that the raids need to be almost overtuned initially to provide a decent challenge for the top teams and then perhaps renormalised for the rest of us. We see that happen every time after a famous team snatches a world first with some crazy tactics. I’m fine with that. But once that adjustment is made the heroic bar needs to stay where it is. Give the teams who like to work for a challenge a stable set of goalposts. Once the gearing process is complete, then consider rebalancing.

If it absolutely has to be a progressively-increasing nerf it would be nice to be able to select the levels rather than just having an on/off switch. It’s a small change but an important one. My guild have talked about going back and trying some of the encounters without the buff, but 0% is a big jump from 25%, or from the 5% and 10% at which we got our first kills. But if we could select 10% to start with that might be more realistic and we could work our way up from there.

I’d like to find a way to solve the problem with the lack of damage to heal, but unfortunately I’m coming up blank. I think it’s a fundamental problem with healing being capped where DPS just isn’t. I don’t like the idea of just splitting the healers up spatially so that you have to take 2 or 3 anyway (the tank solution), because it doesn’t really help with the boredom problem.

Suggestions would be welcome.

As is my wont this post got a bit long, so if you want to skip to a specific part here’s links to the discussion of spells, their costs and performance, Spirit Shell, Rapture, Talents and Glyphs.

Bear in mind that I’m still only level 86 as I write this, and the experience changes a lot as you level up.

The Gotcha Test

The first thing I do when I log into a beta or PTR is what I think of as the “Gotcha!” test. I take a close look at the HPS, HPM and costs of all our spells. Why? Remember Flash Heal in Wrath? And in Cataclysm? That’s what I’m looking for, a go-to ability that’s undergone a drastic shift. Here’s the list at level 85, at my gear level which is ilvl 404 on Live:

Priest Spells, Costs and Performance (Build 15677)

Notice that the mana costs are all nice neat round numbers. That’s because all healers now have a fixed mana pool of 100,000 MP (except gnomes, who have 105,000 MP thanks to our racial!) and spells cost a fixed percentage of our maximum mana.

No huge surprises in there this time, so I won’t go into too much detail. Most of the spells are where they have been in Cataclysm, which is nice. Flash Heal and Power Word: Shield remain our fast, expensive emergency heals. They have pretty punishing HPM and high costs, but they’re quick. Penance is still earning its cooldown with comparable HPS to Flash Heal but half the mana cost, and Prayer of Healing is still good when you have 3 or more people to heal up.

On the subject of abilities, there’s a new page on the spellbook labelled Core Abilities:

Priest Core Abilities Tab (Build 15677)

This is a helpful little nugget to nudge new players in the right direction when picking up a spec for the first time, or returning to a spec after a while away. It might be nice to draw attention to this tab more obviously, maybe as a tutorial tip, because it’s not even in the Talents window so you could easily overlook it.

Spirit Shell

While for a while Spirit Shell was an absorb replacement for Greater Heal, that design was rolled back in a recent build in favour of giving us GH back and redesigning Spirit Shell. Personally, I like what they’ve done with the spell.

Spirit Shell is a 15s self-buff on a 1 minute cooldown that turns all the heals you cast into absorbs with their own 15s duration. According to Ghostcrawler it’s been designed to take account of Divine Aegis (by increasing the size of the bubble by your crit chance so if, for example, you have 20% crit chance your bubble will be 120% of the size of the heal), the bubble size benefits from Grace in the same way the original heals would, and the bubbles also scale with Mastery. Note that the bubbles don’t “crit”, your crit chance has already been taken into account.

To put some numbers on this, imagine you hit Spirit Shell, then cast Greater Heal on your tank. Suppose, for the sake of argument, a baseline Greater Heal is good for 50,000 HP.
I have 15% crit chance, so that gives me a bubble of 50,000 * 1.15 = 57,500 HP.
I also have 25.73% stronger bubbles from Mastery, which takes my bubble up to 57,500 * 1.2573 = 72,295 HP.
Add in a triple-stacked Grace for a 30% boost, and my Greater Heal bubble is up to a whopping 72,295 * 1.30 = 93,983 HP.

That’s good stuff!

The current implementation is still a little early. Currently it’s not actually benefiting from any of those extra effects so we’re stuck with the basic heal. There’s also the open question, which Ghostcrawler acknowledged is still one they don’t have an answer for, of how stacking and capping these bubbles will work. Currently the Spirit Shell shields from different heals stack with each other (they create separate buffs for themselves depending on the spell) but casting the same spell twice refreshes the duration but replaces the absorb amount with the latest value, even if it’s lower.

I expect both of these behaviours to change and I wouldn’t be surprised to see the effect end up working more like DA does, where all the heals contribute to a single bubble buff which stacks up to a cap. The developers did point out that they don’t like us feeling like we need to spam something up to a cap (PoH/DA, anyone?), but I don’t think I mind that sort of mechanic. We’ll have to see how it plays out.

The utility of this is centred around preparing for and preventing damage. Know the Elementium Bolt is about to splash down, or your tank’s going to get Impaled? Get those bubbles out there to take the edge off it. The fact that it scales with Mastery means that you’ll get a slight healing boost out of this cooldown as well (Mastery affects the whole bubble, rather than just the DA portion of the heal), but the tradeoff if that you’ll have to have enough damage coming out to take proper advantage of the absorbs.

Rapture

Rapture is something of a vexed subject at the moment.

Rapture, on Beta and on Live, returns a lump of mana when your PW:S breaks; on Live it’s a fraction of your total mana, on the Beta it’s 150% of your Spirit. On Live this is (significantly) more than the PW:S cost to cast, making it an important source of mana regeneration, whereas on Beta the return is less than the cost of PW:S.

If we consider Rapture as a regeneration mechanic, it’s a slightly problematic one. The objections been gone over several times, including in the links above, but they more or less come down to difficulties in getting PW:S to break reliably when the damage is light or unpredictable or cases where you have multiple Disc Priests fighting over opportunities to bubble a single tank.

This unreliability is a problem on Live because Rapture is a form of “active mana regeneration”, like a potion on a 12s cooldown, and it’s a major part of our mana equation – we cast a bubble every 12 seconds to give us the mana we need to do whatever it is we actually want to be doing – and because it’s so powerful we don’t bother with Spirit for the most part. Imagine if your Shadowfiend had a 50% miss chance, or your Hymn of Hope didn’t actually give you any mana back half the time. Oh, wait…

However, Ghostcrawler explained that that this wasn’t actually the intention of Rapture:

Rapture isn’t trying to be Telluric Currents. You shouldn’t spam PW:Shield when you need mana. Rapture is intended to offset the cost of PW:Shield when the latter is used intelligently.

So instead of thinking of Rapture as part of our mana regeneration, instead we should think of it as a discount on casting PW:S as long as we don’t do it too often and pick a target that’s actually going to take damage. Think of it as a proc like Surge of Light, giving us a cheap PW:S every now and then instead of a free Flash Heal, only it doesn’t proc randomly but activates every 12 seconds instead. I still think there’s a possible issue with PW:S needing to break, especially in the case where you have two Disc Priests fighting over the damage, but you can at least see why that design is there, and that might be an application of the Divine Insight talent (call-ahead!).

Have a look back at the table, and look at the HPS and HPM of PW:S with and without Rapture. Without Rapture it’s still our best HPS ability, but the cost is punishing. Factor in a Rapture proc though and it’s suddenly right up there with our best HPM abilities as well.

There’s still one small wrinkle though, and that’s Meditation. You see, Meditation for Disc Priests is 25%, whereas it’s 50% for every other healing spec. The reason for this is that because Rapture makes PW:S so cheap and so powerful (when we weave it in) we can achieve the same output as the other specs for a smaller mana cost. To balance out this lower cost, our background regen is lowered to match.

The upshot is that if we don’t use PW:S at all, or don’t use it especially intelligently, we’ll end up a little behind the other specs mana-wise. If we use it exceptionally well, we’ll potentially end up ahead. Now the ball’s in Blizzard’s court, and they’ll need to tweak the numbers as the Beta progresses and we hit the level 90 content to make sure we’re balanced.

Talents

I’ve not done a talent run-down in a while, so let’s see where we’re at with those.

Level 15

Priest Level 15 Talents (Build 15677)

Level 15 remains the “CC” tier. Void Tendrils summons a Tendril for every mob within 8 yards of you that roots it for up to 20 seconds; Psyfiend lets you spawn a Psyfiend at a location you choose that fears a mob attacking you every 1.5s; Dominate Mind is Mind Control. Videos of the first two are below for your enjoyment.

Void Tendrils:

Psyfiend:

Personally I’d go with Void Tendrils as my standard pick, just because fear is often a risky proposition. But I can see a lot of value in the Psyfiend in PvP. Throw it down on a flag or into a tower and watch the fun, or maybe just use it to keep people off you.

Level 30

Priest Level 30 Talents (Build 15677)

At Level 30 you’ve got the movement talents. Body and Soul is the same ability we’ve known and envied for two expansions, only now it’s available to all Priests regardless of spec. The contender for PvE is Angelic Feather, which lets you place up to 3 feathers on the ground that grant a movement speed boost to the next person to step on them. If you have a known kite patch or need to keep someone moving at speed for a while then Angelic Feather is stronger than Body and Soul, but Body and Soul is more flexible if you just need to get someone moving and don’t necessarily know who it’s going to be. Tailor your choice to the situaion.

Phantasm looks at first glance like more of a PvP choice, although don’t rule it out entirely for PvE either. It makes your Fade remove all movement-impairing effects and makes you untargetable by ranged attacks and immune to movement-impairing effects for 3 seconds. The untargetability might have niche applications (I wonder if it would make you immune to Shrapnel, for example) but the freedom of movement could be handier.

I suspect the choice will usually be between Angelic Feather and Body and Soul for PvE, but it’s nice to have the option of Phantasm as well.

Level 45

Priest Level 45 Talents (Build 15677)

Level 45 is the first tier where you get to actually improve your output. From Darkness, Comes Light (FD,CL), which still has that extraneous and slightly grating comma, gives you a 15% chance to proc a free, instant Flash Heal when you use (most of) your single-target heals. The list includes Smite, but not Penance or Holy Fire; this may change, I’d certainly expect to see Penance in that list. Given the high HPS of Flash Heal, this is a strong talent if you’re using a good number of single-target heals.

Mindbender replaces your Shadowfiend and deals double the damage and gives back double the mana. Because everything scales off base mana and base mana is fixed, your Mindbender will return 72% of your mana bar (assuming he doesn’t miss) compared to 36% for the Shadowfiend. This extra mana allows you to use more of the expensive spells, and is a great choice if you don’t think you’ll see the benefit of FD,CL, if you’re AoE healing, for example.

And finally we have Archangel, another old friends that’s been opened up to all three specs. This is a straight up output boost for 18s on a 30s cooldown, assuming you’re able to weave in the requisite number of Smites, Holy Fires and Penances to stack Evangelism up to 5. That’s right: Penance stacks Evangelism now, one stack per tick, and causes Atonement heals as well, so you shouldn’t have any trouble getting Evangelism stacked.

In this tier you’re picking what you need. The first two are all about efficiency, the third is about simple output. I suspect we’ll shift from the left to the right as the expansion progresses and mana becomes less of an issue, and at the start we’ll be interested mostly in FD,CL for tank healing and Mindbender for raid healing, although I’ll admit I’ve not sat down and worked through them in detail yet.

Level 60

Priest Level 60 Talents (Build 15677)

Level 60 is all about taking care of yourself. You get a choice of an instant 30% self-heal on a 2-minute cooldown (Desperate Prayer), a shield for 20% of your HP when you’re damaged below 30% of your health every 90s (Angelic Bulwark) and the new Spectral Guise.

Spectral Guise is an interesting talent. When you hit it you spawn a clone of yourself which your enemies will attack, while you get stealthed for 6 seconds or until your clone (“your true form”) is hit 3 times. You can either use the time to run away or to throw a couple of heals on yourself unimpeded.

Spectral Guise feels more solo- or PvP-orientated than the other two since you don’t often take direct attacks as a healer in raids, but it may be useful to save you from a powerful attack directed your way (again Shrapnel comes to mind), since you don’t share in the the damage your clone takes.

Level 75

Priest Level 75 Talents (Build 15677)

Here’s where things get really weird, with a jumble of talents. Twist of Fate gives you a 15% damage or healing buff after damaging or healing a target under 20% HP. I can see this possible being useful for handling low-health enrage phases: throw a HF on the boss at 19% and enjoy 15% extra healing for a while, as well as the more orthodox behaviour of rewarding triage-style healing of the lowest people when the raid is weakened.

Alternatively you could go for Power Infusion for 20% faster, 20% cheaper spell for 15s every 2 minutes either for you or for a friend.

The real wildcard is Divine Insight. For Disc Priests this procs from Penance casts and allows your next PW:S to ignore and to not cause Weakened Soul.
I can see two main uses for this. It’d be pretty handy if you needed a quick throughput boost on a single target because it would let you to throw out a PW:S, Penance, PW:S combination, and it would also be useful to let you maximise the frequency of your Rapture-cheapened PW:S casts even if you or another Priest has already got Weakened Soul on your target.

Level 90

Priest Level 90 Talents (Build 15677)

Until we’re able to actually play with these all we can do is speculate. I’ll link the three options, but reserve comment until they’re opened up on the Beta.

Your choice at level 90 is between:
Cascade, Divine Star, and Halo.

Glyphs

Since the Prime Glyphs have been removed, we’re left with the utility-focused Major Glyphs and the cosmetic Minor Glyphs.

The minors are all more or less unchanged. Shadow Protection went away with the removal of spell resistances, and we got Glyph of the Heavens instead. This one makes your Levitate targets appear to be floating on a cloud. Funky!

As for Majors, a lot are unchanged, but there are a few interesting changes.

• Glyph of Dispel Magic – Deals damage when you dispel an enemy, rather than healing when you dispel a friendly.
• Glyph of Purify – Heals 3% of max HP when you dispel a friendly. Dispel Magic is now our offensive dispel, while Purify is our defensive dispel/cleanse ability.
• Glyph of Fade – Reduces all damage taken by 10% when you Fade, which could be mighty handy.
• Glyph of Holy Fire – Makes Holy Fire instant-cast. Doesn’t save you any time if you’re able to stand still, but could add a valuable extra tool to our healing-on-the-run toolkit.
• Glyph of Levitate – Increases your movement speed by 10% while you’re levitating and for 10s afterwards.
• Glyph of Penance – Allows you to cast Penance while moving, but increases the cost of Penance by 20%. If you need healing on the run this is a good bet. The cost just stops it from being a no-brainer.
• Glyph of Power Word: Shield – Similar to the old version, but where the healing used to be a bonus, this time the healing is taken out of the absorb instead.

On topic, I’m finally in the beta. Broadband being what it is down here in New Zealand, with download caps being the rule rather than the exception, I’m not going to be able to download the whole thing until the end of the month, but I am logging in and beginning to explore, so expect to start seeing some beta impressions and commentary as the beta rolls on.

At the moment I’m busy sorting out the basics of the UI and spells. Addons are disabled at this point and /cast appears to be broken or extremely buggy in macros too. Folks, we’re doing this the old-fashioned way!
I’m also a little sad that my Savior of Azeroth title didn’t carry over, but I do still have my Twilight Harbinger so I retain some epeen potential.

I’ll be spending most of my time on Lost Isles-US, where I’m Malevica on Alliance and (when my premade arrives) I’ll grab some variation of that name on the Horde side too so I have the opportunity to test both factions.
I’m also intending to copy over my Paladin tank or a premade Paladin and perhaps other healing classes as well, but time will tell how much testing I get to do on classes other than the Priest.

As always I’ll categorise beta posts and mark them in the title, so you can avoid potential spoilers if you prefer.

So watch this space, and let’s have some fun!

Context is King

I’ve been flirting with heroic raiding for the last two expansions, but it took me a while to work my way through the ranks of guilds raiding progressively closer to the cutting edge before finally ending up in a guild that was in the running for the top of the server charts.

WotLK was the first time I managed to join a guild that was running hardmode and heroic content, but we didn’t manage to kill heroic Anub’Arak or heroic Lich King on 25-man, only on 10-man with 25-man gear. Not that I’m not proud of the team I achieved those feats with, we all worked hard for them and they were a great bunch of people to raid with, but I still felt we fell short of what some members of the guild could, and probably should, have achieved in the expansion.

In Cataclysm I only got a couple of heroic bosses down in Tier 11 before rerolling yet again to Oceanic so that was a bit of a washout, and reaching 85 midway through Firelands pretty much put paid to my chances of earning a heroic Ragnaros kill before Dragon Soul (although we did go 6/7H post-nerf after starting the guild only weeks before). So DS with <;Abraxas>; was my big opportunity to really push progression and I’m very grateful for the opportunity and for the victory.

What my previous experience gave me was a sense of what heroic fights entailed mechanically but what I’d missed out on from being late to the heroic party and not raiding heroics relatively early, with less gear and thus at the difficult end of the progression curve was a sense of what those fights require of raiders personally.

Heroics Require Focus

And by this I mean total, full-time concentration. When an encounter is really stretching your team’s limits, when your tank is fractions of a second away from dropping dead and when those green bars just don’t seem to ever want to come up again you absolutely have to pay attention the whole time. Glance at your chat log and someone might end up dead. Fail to spot an enemy spell cast and don’t hit your cooldown in time, someone’s dead. Stand in the fire for a second too long and your HPS will be zero for the rest of the fight.

And it’s not just paying attention, it’s also having to constantly think. There’s so little time that you can spend just mashing the same button and waiting for a big blue DBM warning; instead you’re watching timers or learning to feel the fight so you can be ready for the next big thing to come at you, switching spells and healing targets on the fly, and working out what your fellow healers are doing.

And let me tell you, this gets exhausting. We raid 9½ hours per week spread over three nights which isn’t much by some standards, but we generally raid hard for those hours with quick re-pulls after wipes and as little downtime as possible. By the end of good progression nights I’m quite often completely frazzled and no use to anyone for a while afterwards. That’s not to say I didn’t enjoy myself, but it’s hard work, mentally, and if you can’t keep it up for the duration of the raid then you’re just going to be wasting time by the end.

Heroics Require Motivation

So we’ve established that healing heroics is sometimes hard work and tiring; that inherently means you need to find your motivation.

You can be intrinsically motivated – motivated by your own reasons like killing bosses makes you happy or you have a desire to be the best healer you can be – or extrinsically motivated – motivated by something outside the task, maybe so your raid leader will stop yelling at you, or for bragging rights or a shiny mount – or a combination, and neither is inherently “better” than the other.

Whatever you use, you need to be able to stay motivated because healing heroic raids is not going to be fun all the time. For me, it’s a combination of factors, and they come in and out of play as progression rolls on, for example:

• At a basic level I want to kill bosses because it makes me happy to overcome a challenge I’ve been set, but I’ll admit sometimes I wonder if it’s worth the stress.
• I also keep turning up because my team needs me and I don’t want to deny other people the opportunity to raid and beat encounters. That’s partly intrinsic because I know that turning up is the right thing to do, and also partly extrinsic because I’ll lose my raid spot if I leave people in the lurch.
• I also set myself targets like improving my usage of a certain spell or cooldown, or beating my numbers compared to last week. Those small, measurable, achievable goals keep me coming back even when a boss takes weeks to move past and it’s frustrating as hell.
• And yes, I want to stand around Stormwind showing off the title and mount that are the metaphorical carrots dangled in front of me every tier. Nothing wrong with that as a motivational tool!

I think that a good team community helps a lot with motivation. If you feel loyalty to your raid team you’re more likely to want to come back day after day to help them out even when you’re not personally having much fun, and some healthy competition and banter can provide side-goals to keep you aiming at something.

Heroics Require a Thick Skin

This is probably the thing that I’ve struggled with the most. We don’t have a culture of yelling at people in Vent as a general rule, but I know when I’ve missed a cooldown or got myself killed or got someone else killed. I am my own worst critic and I set myself standards which are probably too high, and I’m very good at beating myself up when I don’t meet them.

At the end of the day, you need to remember that heroic raiding is difficult. You will make mistakes and you will cause wipes, everyone does. And because of that you’ll probably be the target of other people’s frustrations at times and even if you don’t get yelled at immediately or called out publicly you’ll probably feel it anyway.

Heroic raiding requires you to pick yourself up, acknowledge your mistakes (to yourself or to your team or both), learn from them, and move on.

Heroics Require Flexibility

Unlike normal modes, where the tuning is a bit more forgiving, heroic raids require the right composition. Over the years the definition of the “right composition” has been made a little more reasonable than stacking your raid with Shaman and making everyone take up leatherworking, but (pre-nerf, at least) 3-healing Ultraxion on heroic just wasn’t happening. So you need to be able to adapt yourself to the demands of the encounter.

For healers (and tanks too, probably more so than for healers) that often means being competent at a DPS spec or being willing to sit out for a mainspec DPS when there’s not a spot for you. I’ve sat on a few bosses and I’ve even tried DPSing, albeit without much success. Fortunately we have healers in the team who are competent in their offspecs, and they make up for my inadequacies!

I’ll also mention that you will sometimes need to work harder, and it might feel like you’re being asked to “carry” another role. We’ve all been there, when you’re dropping a healer because you’re hitting a berserk timer instead of giving your DPS the kick up the backside (you feel) they really deserve. Maybe it’s not fair to make you work harder, maybe other guilds manage just fine with 3 healers instead of 2, but you have to at least be willing to give it your best shot. Whatever it takes to get the boss down, even if that means going way outside your comfort zone.

Flexibility also means tailoring your spec and glyphs to the encounter you’re currently working on, and that’s something everyone will end up doing to some extent. Every fight is different and you can’t rely on one spec, one glyph setup and one reforge and never change anything for an entire tier. You need to think ahead about the mechanics, and look back at logs, to see where you can improve or what needs to change.

Heroics Require Analysis

Which leads nicely to the last thing on my list: you have to be analytical. Not your raid leader or your healing lead, you! And by “you” I of course mean “everyone”. You need to analyse your own performance, your raid’s performance and your strategy and also be able to communicate your ideas to the team (or at least to your raid leader) clearly and concisely.

Your raid leader will have an idea of the strategy they want to employ; they’ve watched the videos, read the guides, understood the mechanics and come up with a plan. Yet the boss is still defeating you. WTF?! Your raid leader will have questions you need to answer, and they can’t answer them on their own. Questions like:

• Why did you die? – Not “what killed you”, plenty of addons will report the proximate cause of your death, but “why were you able to be killed”. The answer might be that you stood in fire for too long, but was there a reason for that? Was everyone too clumped up? Were you preoccupied by too many things to watch? Is something preventing you from seeing the spell effects? Do we need to call out that mechanic? When your raid leader asks a question like this, pretend they’re really asking “how can we help prevent this from happening again”.
• Why didn’t X get healed? – Maybe X got 2-shot and you couldn’t have healed him up, that’s good information. Perhaps a healer was out of commission (Ice Tombed, maybe) and no one noticed. Maybe someone took an unexpected damage spike and everyone switched off the tank to heal him up. To answer this question well you need to understand your assignment and how it relates to everyone else’s, and bear in mind that those assignments might not be formal, they might just be what the healers expect each other to do.
• Why is your HPS (or DPS) so low? – Bad answer: “I don’t know”. Worse answer: “<;myClass>; sucks on this fight. Better answers should relate to the strategy or mechanics. Is there too much movement? Are you missing buffs? Are you not maximising AoE (or cleave, for DPS) opportunities? Bad timing for cooldowns? You get the picture.

I’ll repeat myself, because I think this is one of the most important things I’d tell a new heroic raider: When your raid leader asks a question about why something happened or didn’t happen, don’t stop at answering the question they asked. Instead pretend they’re really asking “how can we help prevent this from happening again?” and answer that question.

Sometimes you might not get your wish, but if you never ask then how will your raid leader know there’s a problem at all? They’re only one person, playing one role, they’re not omniscient.

Is It Worth It?

Absolutely, one hundred per cent, without a doubt.

But do bear in mind that heroic raiding will not always be fun. In the words of the great Del Preston:

It will not be easy.

You will get tired. You will get blisters. You will get aches and pains.

But you will also get good.

Clearly there’s not One True Answer for every player in every type of content at every level of the game, so let’s look at the Big Three: levelling, heroics and entry-level raiding, and hard-mode raiding.

I’m also going to conflate Evangelism/Archangel with Atonement here and deal with them together; you could take one without the other, but you probably shouldn’t.

Levelling

The emailer said they they’d levelled as Atonement all the way through to heroics and I cannot recommend this approach enough. If you ask me “Holy or Disc for levelling?”, it’s got to be Disc all the way, baby!

Whether you’re soloing or instancing Penance is amazingly powerful, and an Atonement spec is the icing on the cake: you’re in a great position to take on more mobs at a time while questing because you don’t have to trade off as much DPS time to heal yourself up, and in instances you’ll often find yourself not needing to directly heal the tank at all, just bubble and then Holy Fire and Smite to your heart’s content. Those tedious dungeons will just fly by!

Bonus points are available for topping the DPS charts, although you’ll probably have to wait for a boss for a chance to beat the tank.

Heroics and Entry-level Raiding

Here’s where things might be a bit more open, albeit only a little. Holy Fire/Smite/Atonement’s place in the max-level Discipline arsenal is two-fold:

• A cheap-ish, medium-throughput, spammable heal; and
• A means of preparing during lulls for a higher damage phase to come.

My answer to the “Atonement or not Atonement?” question in entry-level content is “Atonement, unless it’s really not working for you”. Let me explain why.

Consider the alternative, which tends to be some variation on this 31/8/2 spec. The main difference is that the 5 points in Evangelism, Archangel and Atonement have been moved into Strength of Soul, Train of Thought and 1 into Inner Sanctum to make up numbers. What that buys you is more frequent Power Word: Shields on your direct healing target (SoS reduces the duration of Weakened Soul when you use your single-target heals) and greater mana efficiency if you cast a lot of Greater Heal (Train of Thought will make Inner Focus come off cooldown sooner).

Notice that both of those talents only really make sense if you’re casting a lot of direct heals on a single target. If you find yourself doing that a lot, then knock yourself out and go grab an Atonement-free spec, but I’d wager you’re probably not.

While you might occasionally run into Lolarthass the Frost DK who didn’t get the memo telling him that no, Death Knights can’t tank in any spec any more, and especially not without some sort of tanking gear, and you might have to spam Greater Heals on him to keep him from being flattened by every trash mob he staggers drunkenly into, generally tanks will be able to hold their own and you won’t need to work too hard to keep people alive. In that scenario Atonement serves as a mana-efficient way to keep the group going through the moderate-to-low damage and the extra DPS you do will help speed things along nicely.

If your tank is complaining that you appear to be too busy DPSing and not healing, feel free to educate them on how things work for Discipline Priests these days and carry on doing what you’re doing. If you’re not wiping and no one’s dying (and the Moonkin isn’t spamming Rejuvs like there’s no tomorrow), then you’re probably doing it right.
And if your tank is insisting that Disc is a PvP spec (yes, it still happens) I suggest you /facepalm ostentatiously, /sigh deeply and drop group. It’s probably for the best.

In LFR the story is similar. Even if you want to be a dedicated tank healer, I strongly suspect you’ll not find enough tank damage to heal to justify the investment in that playstyle. LFR is dominated by raid damage at the best of times, and in a 25-man raid you’re likely to find yourself working with Earth Shields and Beacons of Light specifically placed on tanks as well as smart heals and Efflorescence that get aimed at the mêlée, so most of the healing tanks need is already being covered.
In my opinion, you’re better off practising weaving Greater Heals and Prayers of Healing in with Smites and Holy Fires and learning to read the encounters to find the best times to build Evangelism and to pop Archangel. That’ll prepare you better for the more difficult tiers of raiding.

But! Always bear in mind that Atonement remains a medium-throughput spell; you can’t just smite-spam and hope to top the meters, and it’s certainly not the solution to every healing problem, you need to get clever about things even in entry-level content. You will need to break out Greater Heals when your tank(s) are taking a beating, you will need to keep Prayer of Mending going when there’s regular damage (the whole of the Madness encounter, for example) and you will need to throw out Prayers of Healing when the group takes damage. Atonement is there to act as filler while you conserve mana and to build Evangelism stacks for when you need them later.

Hard-mode Raiding

When it comes to heroic (or progression) raiding, there’s a very strong case for taking Atonement on every encounter. In fact, Derevka made that case back in December.

The short version is that a 15% boost to your healing for 18 seconds every 30 seconds is just too good to pass up when the content is stretching your healing team’s throughput, and the added DPS you can contribute is invaluable when you’re bumping up against enrage timers. And there’s essentially no penalty if you know the encounter well enough.

Damage profiles on most raid encounters are cyclic, meaning that there are clear peaks where you need extra output and convenient troughs where you can build up Evangelism in preparation. If you’re progressing through heroic raid content you should be adept at reading encounters and spotting these phases and planning your Archangel use accordingly. You should also sense when you’re OK to Smite and when you should switch to “real”, targeted heals instead.

 
Ultimately, what sets the great healers apart from the merely very good is their in-depth encounter knowledge which allows them to pick the right abilities to use at the right times. For Discipline Priests timing Archangel is a huge part of that.

Fight Summary

So you’ve killed Spine and now you’re ready for Madness. The good news is that Madness is probably easier than Spine, at least from a technical point of view, and the gear requirements are similar or lower. The bad news is that it’s another 14-minute-plus fight with a long ramp-up time.

There’s not too much different on Heroic, but if you’re used to normal mode you’ll have to tighten up quite a bit to get through it. You can take two tanks but it’s doable with one and you may find you need to go with one tank to beat the berserk timer.

I’ll cover positioning first, then we’ll look at the new mechanic in Phase 1, the Corrupting Parasite, then I’ll cover dealing with Impales before finally talking about each of the phases, including a close look at Phase 2.

Positioning

The first thing you’ll need to tighten up on is your positioning. The Mutated Corruption’s Crush hits very hard, around 80-100k, so you want to minimise the number of people hit by it both to reduce healer mana expenditure and to prevent a second Crush from killing someone. The way to do this is to have the ranged spread out in a curve near the back of the island behind the tank, and the mêlée spread out on the other side:

R are ranged and healers; M are mêlée; T is the tank; and the orange blob is the Mutated Corruption

That’s your baseline positioning while the Mutated Corruption is alive. There will be perturbations in response to mechanics, and I’ll get to those, but you should always aim to return to this general layout.

Phase 1 – Corrupting Parasites

This is the new mechanic on the islands. Twice during the phase, on a fixed timer, Deathwing will cast Corrupting Parasite on a random player. The first comes just as the first Impale is due and the second comes around the time the Regenerative Bloods spawn.

Corrupting Parasite lasts 10 seconds and deals increasing Shadow damage every second while it lasts, starting at 18,000 and topping out at around 80,000 (before resistances), so it’s worth assigning someone to watch this person so they don’t slip through the cracks. When the debuff ends it kicks out a Parasitic Backlash dealing 250,000 Fire damage to everyone within 10 yards and spawns a Corrupting Parasite with around 2.7 million HP. You need to focus on this because at the end of its 10-second Unstable Corruption cast it will explode, dealing damage equal to its remaining HP split across the whole raid.

The short version is that you need the Parasite placed 10 yards away from other people and then you need to kill it, or at least bring it to a safe HP level (around 30% is fine, that’s 80,000 Fire damage per person), before it explodes. Where and how you do that is important though, because efficiency of DPS is a key factor on this fight so you beat the berserk timer on each island and, more importantly, so you have time in hand to take Phase 2 at your own pace.

The first Parasite on each island should be dropped right next to the Mutated Corruption, on the edge of the island, so that you can cleave the Mutated Corruption along with the Parasite. The Parasite is the top priority but adding extra damage to the Mutated Corruption is no bad thing. On the diagram above that’s between the tank and the mêlée so you may need to shuffle around to make sure there’s room, especially if you have more mêlée DPS than I’ve shown there. Also, be careful not to fall off the edge or the Parasite will end up on the wrong island and out of range of DPS. Not that that happened to me, of course…

The second Parasite will spawn as the Mutated Corruption is dying, so this time you want to drop it next to the Arm or Wing Tentacle instead. The Regenerative Bloods will have spawned by this time, so they’ll also be brought over to the Arm or Wing Tentacle and everything should be AoE’d down together for maximum DPS efficiency.

Running through, or standing in, Nozdormu’s Time Zone will slow the tick rate of the debuff, allowing you to extend the time before the Parasite spawns. Basically, you can use this if your Mutated Corruption isn’t quite dying in time to buy time for the tank to bring the Regenerative Bloods over, but if you find you’re waiting for the Parasite to spawn then go around the Time Zone instead. We found the Time Zone handy on the third island, but of course your mileage may vary.

Handling Impale

The Mutated Corruption’s Impale is a big deal on heroic. It deals 840,000 Physical damage as a baseline, and you really can’t afford to take a second one for twice that. Two things need to happen: you need a decent cooldown rotation for any Impales your tank(s) will take, and you need a solution to second Impales.

On the cooldown front, you will need to stack tank cooldowns and healer cooldowns to get through the damage. The first island is easy enough because you have Dream available, so any decent (40% or more) cooldown will do. On the next island you’ll need to stack two 40% or higher cooldowns, such as Shield Wall and Pain Suppression. On the third you’ll not have Alexstrasza’s 20% HP boost so this is a good time to pop a Last Stand-equivalent as well as those cooldowns, and on the last island healers’ 3-minute cooldowns should be up again. Remember that Power Word: Barrier can be used as a 25% cooldown, and if you’re really pushed Spirit Link Totem is a 10% cooldown, which might make the difference.
The Stay of Execution trinket is another 20% cooldown that tanks can use on every island (it applies after any other damage-reducing cooldowns have taken effect, so the damage cap isn’t a problem).

On top of cooldowns, Inspiration/Ancestral Fortitude are good for a further 10% reduction and should be kept up on the tank, and Demoralising Shout/Roar should be kept up on the Mutated Corruption for a 10% Physical damage reduction. Tanks also have their own damage reduction from their tanking stance, presence, form or aura (10%, 14%, 18%, and 10% respectively) which should be added in as well. And don’t forget the raid-wide nerf, Power of the Aspects, which as I write this is at 15%.

Big warning: “cheat death” abilities like Ardent Defender Guardian Spirit do not work on this encounter. AD’s 20% damage reduction does work, but it will not prevent a player’s death.

Just multiply together your cooldowns and damage reductions and check they’ll be enough. For example, here’s our setup for each island, with a Warrior tank:

1. 840,000 x 0.85 (Power of the Aspects) x 0.90 (Demo Shout) x 0.90 (Inspiration/Ancestral Fortitude) x 0.90 (Defensive Stance) x 0.60 (Shield Wall) x 0.80 (Stay of Execution) x 0.50 (Dream) = 124,921
2. 840,000 x 0.85 (PotA) x 0.90 (Demo Shout) x 0.90 (Insp/AF) x 0.90 (Def Stance) x 0.60 (Shld Wall) x 0.80 (SoEx) x 0.60 (Pain Suppression) = 149,906
3. 840,000 x 0.85 (PotA) x 0.90 (Demo Shout) x 0.90 (Insp/AF) x 0.90 (Def Stance) x 0.60 (Shld Wall) x 0.80 (SoEx, not totally effective because the hit exceeds the absorb cap) = 255,324 (Survived by using Last Stand and being topped off)
4. 840,000 x 0.85 (PotA) x 0.90 (Demo Shout) x 0.90 (Insp/AF) x 0.90 (Def Stance) x 0.60 (Shld Wall) x 0.80 (SoEx) x 0.60 (Pain Suppression) = 149,906

Now, for the second Impale on an island you can either have a second tank or use a neat little trick to avoid having to worry about the Impale at all. What this relies on is the fact that the Mutated Corruption will Impale anyone it can reach, so you can force it to Impale a specific person by having everyone run out so that they are the only person in range when the cooldown is up. Of course the soaker will also be taking mêlée hits too while before the Impale goes off, so they need to be able to take care of themselves for a short time.

The best choice for this job is a Shadow Priest, because they can use Dispersion to reduce the Impale to a meagre 57,834 Physical damage, and they can do this on every island. If you don’t have a Shadow Priest, you can use a Rogue or Hunter for the same job. Have them step in with Evasion or Deterrence up so they don’t get killed by mêlée swings, and as soon as they get the Impale debuff they should Vanish or Feign Death. This clears the debuff and voilà, you’ve skipped an entire Impale! Just make sure to let the tank get back in first afterwards, or else the keenest mêlée will get killed instead.

Phase 1 Overview

We’ve been through the new abilties in detail, but it’s worth stepping back and looking at them in context.

To begin with, island order. I recommend Ysera, Alexstrasza, Nozdormu and then Kalecgos, as on normal mode. With the extra Crush damage and cooldowns being tied up you need Nozdormu as long as possible, but you still need Kalecgos more to ensure you get everything killed in good time.

Here’s the order of events for a sample island:

1. At the start you’ll hit the Arm or Wing Tentacle for a while, then you’ll break off and get into your arcs ready for the Mutated Corruption. Do not bring the Tentacle under 80% HP on the latter two islands until after the Regenerative Bloods have been killed, you don’t want Blistering Tentacles when you’re busy dealing with other things
2. Shortly after that the first Corrupting Parasite will be cast, which should be delivered to the spot right in front of the Mutated Corruption
• On the first island you should ignore the Parasite, save DPS and use Dream when it is about to explode
• On subsequent islands it should be killed, cleaving the Mutated Corruption where possible
3. A couple of seconds after the Corrupting Parasite cast comes the first Impale. Stick with your cooldown rotation and all will be fine
4. You get a ~20 second lull here before the Elementium Bolt is cast, which all DPS should switch to and kill before it lands as usual
5. Shortly after the Bolt is dealt with the second Impale comes out. You’ve got a plan for this, so execute it
6. Immediately after the second Impale the Regenerative Bloods will spawn. These should be brought and misdirected to the tank and held while the Mutated Corruption dies
7. A few seconds after the Bloods spawn the second Parasite gets cast. This should be dropped over by the Arm or Wing tentacle
8. Once the Parasite is dropped and the Mutated Corruption is dead, the tank should drag the Regenerative Bloods over to the Arm or Wing Tentacle and the whole lot should be AoE’d down.
9. At this point the fight is the same as normal mode. Kill the Arm or Wing Tentacle, and any other tentacles that might spawn

On the fourth island you should handle the Elementium Bolt as usual, running away from it, popping PW:B if you use it and Tranqs and Divine Hymns if you have them. However to help prevent half the raid getting Crushed while clumped in the bubble you can have people with personal cooldowns stand outside the bubble instead. Your healers will thank you!

Each of the islands proceeds along much the same lines, although the general level of damage increases as you go along. There’s a lot to take in but there’s also a clear rhythm to the encounter which you’ll soon figure out, and it’ll end up feeling a lot less complicated than it looks.

Phase 2

Hopefully you’ve completed Phase 1 in good time, because Phase 2 is as much about control as raw output, although there’s a hefty burst DPS requirement too.

The Elementium Fragments are still in play, as are the Elementium Terrors. Handle them as you always would: kill them ASAP, use Dream if you get targeted by Shrapnel and tank the Terrors in the Time Zone to slow the rate at which they can stack Tetanus. On heroic 7-8 stacks is quite enough, needing external cooldowns and intensive healing to survive.

The new aspect is the Congealing Blood. These start to spawn at 15.9%, 10.9% and 5.9% from approximately the locations shown on the screenshot below, and slime their way towards Deathwing. If they reach him they heal him for 1% each. Even one getting through could spell disaster though, because if you take Deathwing above a trigger point he’ll spawn more Congealing Bloods when you DPS him down past it again.

Congealing Blood approximate spawn locations

The Bloods cannot be stunned, rooted or knocked back, so slows and AoE damage are vital here. Be careful not to overwrite slowing effects. We chose to have our rogue use Fan of Knives with Crippling Poison on the Bloods to keep them slowed, and we had a DK with Chillblains helping out as well while everyone else focused on killing them.

The key to this phase is control and not trying to do too much at once. If your tank can drop the Tetanus debuff easily (DK, Paladin) then go ahead and tank the Terrors with the Bloods and AOE everything together. However at 15% this isn’t necessary any more, you have time to kill each thing in turn, and the encounter feels a lot more manageable if you take your time.

Here’s the sequence we went for:

1. DPS Deathwing to 17% (not much lower so that DoTs and spellweave (the AoE bonus you get from Kalecgos) don’t take him under prematurely)
2. Kill the first Fragments
3. Kill the first Terrors
4. Push Deathwing under 15.9%
5. Kill the Congealing Bloods
6. Push Deathwing under 10.9%
7. Kill the Congealing Bloods
8. Kill the second Fragments
9. Kill the second Terrors
10. Push Deathwing under 5.9%
11. Kill the Congealing Bloods
12. Kill Deathwing, ignoring any Fragments that might spawn at the end

The timing was pretty tight on getting the second Bloods killed before the second set of Fragments spawned but we ended the encounter with 30-40 seconds in hand, so there was time for us to have waited if necessary to survive.

Spec and Glyphs

There’s a bit of everything to deal with, so picking a focused spec is a little tricky. I stuck with the Atonement spec because with the fixed range on Atonement you can do a good job of smart-healing people from Crushes. Plus Atonement benefits from the double damage on the Arm and Wing Tentacles for the third minute on each island making it competitive HPS at a very low cost. Archangel is also great to pop when the Blistering Tentacles spawn for a bit of an extra boost to your raid healing, and for healing up after the Elementium Bolt on the fourth island.

Although PW:B gets used I found that people weren’t standing in it enough to make the glyph worthwhile. I ended up settling for PW:S, PoH and Penance as Prime glyphs. Penance is good as a quick heal on Crushed people, for keeping Inspiration on the tank or for keeping up my Heart of Unliving stacks, and I was casting PW:S frequently for Rapture procs.

For Majors I swapped Dispel for Glyph of Prayer of Mending, since there’s nothing to Dispel, and because PoM should be bouncing for most of the fight.

And once again, get the Glyph of Fading. You’ll need it every time the Regenerative Bloods come up, and every little helps.

Cooldown Usage

Your tank cooldowns will be almost entirely dictated by the fight and your strategy. Because you’ll typically spend up to 2 and a half minutes per island you can’t guarantee that your 3-minute cooldowns will be available for the same point on every island, so play it safe and plan to have them up every other plate. Your PW:B will be needed on the fourth island, so avoid using it on the third, although there may just be enough time between the first impale on the third and the Bolt on the fourth, it’ll depend on your raid’s DPS and speed.

In Phase 2, Pain Suppression should be used on the Terror tank when their Tetanus stacks reach 6 or above, followed by spam-healing until the debuff fades. You can either use PW:B on the raid to mitigate the damage later on or on the tank again for the next set of Terrors, depending on the other cooldowns used. Bear in mind that if you can get a few raid members to stand in it Spirit Link Totem can be a lifesaver for a Terror tank, giving them access to a much larger effective health pool, so you may wish to use your PW:B on the raid instead.

Leap of Faith isn’t a terribly useful ability on this fight if the strategy is being executed correctly. You can extract people who are slow to move away from the Mutated Corruption before an Impale, but otherwise no one should have trouble getting to where they need to be.

Timing Shadowfiend and Hymn of Hope is tricky here. Ideally you’d get them in three times, given a 14-minute-ish duration, but it’s quite possible you just won’t need them on the first island. I’d recommend using them early anyway, you might help someone with the Hymn of Hope and the DPS from the Shadowfiend can help get the Mutated Corruption out of the way a fraction quicker. And even if most of the mana is wasted, it’s better than not casting them at all.
If you cast them after you’ve healed up the first Parasite explosion you’ll have a mana deficit to recover, and then you can cast them together on the third island and on Deathwing’s head during Phase 2.

Other Tips

Keep Fade handy for the Regenerative Blood spawn, especially if you’re 1-tanking the fight. Fade early too to avoid getting any DoT stacks and keep them going where they’re supposed to.

Rapture is so important for maintaining your mana on this encounter. If you’ve got a bit sloppy up to now, it’s time to get back on the straight and narrow. Remember, even after the Mutated Corruption dies there’s going to be enough raid damage to burst the bubble pretty reliably so cast it on anyone when the Rapture ICD expires and enjoy vastly improved mana regen.

That same raid damage also means PoM will almost never fail to use all of its charges, making it quite mana-efficient and a good use of a GCD. Keep it going as much as is practical, especially once the Arm or Wing Tentacles are below 70%.

On the first and second set of Congealing Bloods in Phase 2 you can help with some Mind Searing. Remember to pick a mêlée DPS to sear off instead of tab-targeting a Blood, or it’ll get interrupted every time the Blood dies.

Finally, not a Discipline tip but a good one anyway: if you have trouble with the portal at the entrance sometimes sending you to Wyrmrest Temple instead of the Maelstrom, go up onto the Skyfire gunship and talk to Sky Captain Swayze to set it in motion, then use the portal in the bridge to get to the Maelstrom. After that, the entrance portal will go to the right place (until the instance resets).

Good luck, and have fun! Comments, questions and additions appreciated.

Fight Summary

On heroic, the Spine of Deathwing fight demands precise timing, fast target-switching, efficient healing and a lot of patience!

The fight will take at least twice as long on heroic as it does on normal because each Burning Tendon has a greatly increased health pool. You should expect to take two burn phases to remove each plate instead of just one. What this also means is that there will be a lot more Corrupted Blood spawning than you would normally be used to, making Blood control by tanks and Blood removal on the rolls much more important.

For ranged DPS, dealing with Fiery Grips quickly becomes really important, given that each tick can take 1/4 of your health away and you might not be healable at that moment. You want to be in position to DPS the Corruption immediately, but you also need to stop DPS quickly once it’s released or you’ll kill it early and end up with an extra Amalgamation killing people. The margin for error is fairly small here. I’ll talk about the timing in detail in the section on Hideous Amalgamations, but if you time things carefully you can avoid having a Fiery Grip during the Burning Tendons phase, which is a huge DPS boost if you’re having trouble getting the Tendons down reliably.

For healers, besides needing a bit more work to remove the Searing Plasma debuff on people and the fight going on a lot longer, the only major mechanic to be changed is the addition of the Blood Corruption debuffs, which I’ll give their own section below before other sections on dealing with Hideous Amalgamations and Corrupted Blood.

Blood Corruption

Every Hideous Amalgamation that spawns will cast Blood Corruption: Death on a random player in the raid. This is a magical debuff with a 15s duration. When it gets dispelled it jumps to another random player and may either stay the same or change into Blood Corruption: Earth. The duration persists through dispels, so you have 15s total before it expires. When it does expire, if it’s still Death (red icon) it will explode and insta-wipe your group; if it’s Earth (yellow icon) it will grant that player Blood of Neltharion, a 20% damage reduction for the rest of the fight (including through combat resses (Anyone able to confirm this?)), stacking up to 2 times for 40% total.

One person (25-man teams may want a second person) should be assigned to dispelling this, and their priority should be:

1. Get rid of any red Death debuffs
2. Get the yellow Earth debuff onto the tanks, up to 2 stacks apiece
3. Get the yellow Earth debuff onto anyone who is likely to pull aggro on Corrupted Blood later in the fight, which tends to mean healers and perhaps melee DPS too.

Because you want this damage reduction on the tanks as soon as possible, the best way to begin the encounter is to kill all four Corruption tentacles, then wait on the roll until all 4 Amalgamations have cast their Blood Corruption. Then roll and throw them off. This gives you 5 Blood Corruption debuffs to work with right from the start and believe me, getting your tanks sorted early when you’re not panicking about healing all the things is a good feeling.

Amalgamation Management

Speaking of those Hideous Amalgamations, let’s look a bit more closely at when, where and how to spawn them, dump them and kill them.

As I’ve mentioned, you want to spawn four pretty quickly at the start, so on the ‘pull’ you’ll kill all four of the active Corruptions; To help your tank pick them up it’s worth killing one side and then the other rather than a random order.
These four are going to be held by the tank(s) until they’ve cast their Blood Corruption and then you should execute a roll to throw them off. At this time, kill the new Corruption and the fight begins properly.

Because the Amalgamations have pretty high health and their Superheated Nucleus pulses hurt a lot you really don’t want them to reach 9 stacks before you’re ready, so make sure your Corrupted Blood is killed on one side of the Spine and your Amalgamations are tanked on the other.

The timing on the Amalgamation’s death is very tight. You need to be watching its health bar, the number of dead Bloods (Residue) on the ground, and the timer for Fiery Grip, and making sure you’re ready to move at the precise time. When there is ~6 seconds to go on the second Grip of that phase, move the Amalgamation across the Spine and into the pile of Residue. It should get to 9 stacks immediately and start pulsing. Hopefully it was at ~5% or less HP when you started moving, and if it’s much above 10% then you may have problems. While the Amalgamation is moving the melee DPS should work on finish off the Amalgamation, the ranged DPS should be DPSing the Corruption to break the Fiery Grip, then switching back to either finish off the Amalgamation or start work on the Burning Tendons.
If you got the timing right there will be a Fiery Grip right after the Burning Tendon goes away, so be ready to quickly kill the Corruption to break it out, then rinse and repeat the previous process.

After every plate is removed you’ll want to execute a roll to clear out some of the Corrupted Blood. Spawn an extra Hideous Amalgamation (so you can soak up more Residue), then AoE down the Corrupted Blood that remains, using raid cooldowns to prevent the Burst damage from killing people. Start the roll as you drag the Hideous Amalgamations through the Residue pile so it soaks up as many as possible, and then the roll will throw it off the Spine safely.
Once again the timing is tight: you should be in the process of starting the roll because if the Amalgamation absorbs nine Residue it will start to pulse, and you really need to minimise the number of pulses it can get off before flying away. If you’re fairly quick on the roll, you’ll also avoid getting a Fiery Grip during the roll, which helps a lot.

Corrupted Blood Management

Mostly because of the length of the fight you will have to deal with a lot more Corrupted Blood on heroic than on normal, and you will need to carefully manage this to stop it causing too many problems.

The first thing to sort out is positioning. On the first plate it’s not so important, but from the second onwards your Blood tank will be having trouble picking the Bloods up fast enough. The best way to have the Bloods remain under control here is to have the ranged and (especially) healers position themselves near the Blood tank so that the tank’s AoE/cleave attacks alone are sufficient to pick up the incoming Blood, leaving taunts free for the few which genuinely go astray.
Pay close attention and be careful to run away when the Amalgamation is due to die, because getting Fiery Gripped next to the Nuclear Blast is just embarrassing.

The next thing to deal with is not killing too many Corrupted Bloods. Any Blood that is killed (barring the Blood that gets thrown off in rolls or used for exploding Amalgamations) will just come back later once it’s slimed its way to the fiery pits at the side, so killing more Blood than you need to just means you have to heal through more Bursts. When each Burst is around 10k Physical damage raid-wide, that’s a lot of unnecessary mana spent. DBM can keep track of how many Residue are on the ground, so keep a close eye on this number and don’t go crazy.

The only way to actually get rid of Blood, which you’ll want to do to keep your tanks from getting splatted on the last couple of Amalgamations, is to throw Residue off. I’ve talked about this before, so I won’t repeat myself.

The final thing to talk about is what happens on the last plate. Once the second plate has been blown off you’ll have AoE’d down most of the remaining Corrupted Blood and thrown them off with Amalgamations in a roll. After this, the first Amalgamation on the third plate should proceed more or less as before, but the rate at which new Corrupted Bloods are arriving is pretty high and after the first Tendon phase your Blood tank will be taking a real beating from all the Blood, requiring very heavy, focused healing.
At some point that tank may very well need to start kiting; if you’ve been on time (2 grips per Amalgamation) and throw off enough Blood, this shouldn’t need to happen until the second half of the last plate, the 6th Amalgamation. The less kiting the better, because it’s easy to make a mistake and have a tank die. The Bloods can be stunned, including by a Paladin’s glyphed Holy Wrath, which helps with the kiting, and Life Grip can be used to help your tank keep distance. If they feel they might take a few hits in passing, they’ll need a cooldown to get through it.

Because one tank is engaged in kiting full-time and not in picking up new Blood, your Amalgamation tank will need to take over picking up the Blood instead. The ranged and healers need to move over to that tank to help with the Blood pickup, and healers need to be aware and give them extra healing. Everyone should be extremely careful not to kill any of these Bloods so the Amalgamation doesn’t gain stacks prematurely.

Spec and Glyphs

As a Disc Priest your primary jobs here will be damage mitigation, dispelling, and DPSing, in that approximate order, and for me that meant an Atonement spec. You could go a different way and go with a tank-healing build with Train of Thought and Strength of Soul if you want more single-target efficiency, but because of the way Grace works and the fact that absorbs don’t help to remove Searing Plasma debuffs you’re far better off letting the other healers focus on clearing the debuffs while you cover the dispels and use PW:S to protect people with Searing Plasma who are taking, or going to take, damage. Atonement is a pretty mana-efficient way to heal, assuming the damage isn’t wasted, and does seem to prefer people with Searing Plasma debuffs (perhaps it sees the debuff as a deficit?).

The key to surviving the fight as a healer is efficiency. Spamming GH bombs around the place for 12 minutes just isn’t practical, nor is it necessary. Slow and steady is the key here.

You’ll also want to pick up Soul Warding so you can quickly throw out a few bubbles before the Amalgamation hits 9 stacks or before a roll.

Glyphs-wise, go with Glyph of Dispel Magic and the Glyph of Power Word: Shield for a bit of extra healing, and make sure you have the Glyph of Power Word: Barrier for the same reason.

And if you don’t have the Glyph of Fading yet, go get it for this fight, you won’t regret it. And keep it, it’s pretty much the only useful third minor glyph. (When was the last time your Shadowfiend died?)

Cooldown Usage

Work with your fellow healers on cooldown rotations. You should expect to have them up once per plate, but not once per Amalgamation. The points where cooldowns are valuable are the rolls, especially if you’re AoEing Blood, and when the Amalgamation pulses at 9 stacks.
We chose to use PW:B on the first roll, then after each plate when Blood was being cleared out before the roll. Tranqs are good to use during or right after rolls to clear out remaining Searing Plasma debuffs and get people topped up. Because of the long cooldown, save Divine Hymn for during or just after the final roll, once the second plate has been removed.
A special note on Spirit Link Totem: the effect ignores Searing Plasma! You still can’t heal the person directly, but healing pumped onto the raid as a whole gets shared with them, so this is hugely valuable when debuffed people people might otherwise die from incoming damage, so we found this handy when the Amalgamation was pulsing.

I found two important places for Pain Suppression, but there was time for at least one other use as well, your choice. The first is on the Amalgamation tank before first roll, when there will be four Amalgamations active. The second important use is on the final plate, where your Blood tank might need to call for it if they run out of stuns or personal cooldowns. Besides that, use it freely on either tank if they start taking too much damage or even on a healer if Bloods have got away.

Besides rescuing people who are standing in a bad place (under the Nuclear Blast, or too far out for the Blood tank to hit their Bloods, for example) this can be used to help keep your Blood tank stay away from the Bloods while kiting them. If you want to use this it’s best to plan it in advance so you can be standing in a sensible place and facing the right direction. There’s nothing quite like failing to LG because you’re facing the wrong direction!

Your Shadowfiend and Hymn of Hope can and should be used together on this fight where possible. Bearing in mind the 12-minute duration you should expect (unless you have extra talent points in it, in which case go your own way on timing too) to get 2 Hymns and 2 Shadowfiends in. I went with throwing out both on the first Burning Tendons to get them on cooldown and they’re not wasted because I’ve usually just burned a ton of mana moving 5 Blood Corruption debuffs around the raid, and then I can use them again on the last Burning Tendons, on the first burn because I really don’t have the time to sit and channel on the second burn.

Other Tips

I think I’ve covered most of it above. I should just re-iterate the need to keep an eye on your mana and be efficient. Don’t look at the meters on this fight because you should expect to be behind, but you bring vital mitigation to the fight as the only way (outside a Spirit Link) to protect people with Searing Plasma from incoming damage, and that can be a life-saver. Plus you free up other healers to do their thing by covering the dispelling duties and add a bit of DPS to the equation.

Good luck, and have fun! Comments, questions and additions welcome as always. (Grav, I’m looking at you!)
