NB: This guide will assume you’ve already read my normal Ultraxion strategy, or otherwise know the details of the fight on normal mode.

Fight Summary

The Ultraxion fight on heroic is pretty much the same as the normal, the difference are fairly small.

The main change you’ll notice as a healer is that the AoE damage is a lot higher, as befits a heroic encounter. The timing intervals remain the same but the hits are higher: 400,000 Shadow damage on 10-heroic vs 300,000 Shadow damage on 10-normal. What’s more, you’ll be going with 2 healers in order to make the enrage timer, so it’s a lot more work than normal mode is.

The second change is that Fading Light is cast on two raid members plus his current tank, as opposed to tank plus one on normal mode. This makes the healing a bit more tricky because the damage will be spikier as more people use Heroic Will and don’t split the damage. Fading Light also leaves a debuff on the tank; unlike on normal, where the debuff leaves the tank unable to generate threat for a few seconds, the heroic debuff increases physical damage taken for 10 seconds. This is a very good way of forcing you to take two proper tanks, but shouldn’t impact on the healing as long as the tanks swap immediately when the debuffs go out.

The final changes are to Hour of Twilight. The small change is that the cast is shorter, 3 seconds instead of 5 seconds. That sounds small, but it matters if you’re used to squeezing an extra round of heals in and you’ll need to carefully adjust your timing.
The big change is that you need two people to soak each Hour instead of just one, and your tanks will not have major cooldowns available often enough for them both to take every single one. You need other people, DPS and healers, to pick up the difference.

I’ll focus on the Hour of Twilight changes, and on handling the increased damage, particularly towards the end of the fight.

Hour of Twilight

As I’ve said, the important change is that you now need two soakers per Hour instead of one. Hour of Twilight happens every 45 seconds, and once you’ve soaked an Hour you get a debuff which prevents you from taking another for 2 minutes. If you try, you die instantly. So you need 6 people to soak the Hour of Twilight, working in three pairs.

But you have other ways to survive this:

• Shadowpriests have Dispersion every 2 minutes (75 seconds with the glyph)
• Fire Mages can use Cauterize once a minute to survive, as long as they get healed up quickly afterwards
• All Mages can Ice Block to avoid the damage, and Paladins can Divine Shield one as well
• Rogues can use Cloak of Shadows every 2 minutes, preventing all magical damage taken
• Hunters can use Deterrence to deflect the spell and take no damage
• Holy Priests can use Guardian Spirit to help someone survive
• Discipline Priests can use Pain Suppression in combination with a minor cooldown such as Barkskin or Anti-Magic Shell. These cooldowns are good, but not good enough on their own

There may be more abilities I’ve missed, I’d be glad to add them to the list!

Healing the last 30 seconds

At 5 minutes in Ultraxion becomes more Unstable for the final time. He goes from casting every 2 seconds to every 1 second, which effectively doubles his damage done. At this point, it’s a race against time to kill him before your healers run out of cooldowns or you’ve used up all your Timeloop charges.

The trick to surviving this is to start rotating raid cooldowns and healing cooldowns from 5 minutes onwards, anyone with a spare personal cooldown should use it, and ideally you get a kill before 5:30 or 5:40. Remember that your tanks will be getting their 4-piece bonuses, which give them an extra raid cooldown to play with. (See Grav’s comment for a great tip for using a Warrior tank’s 4-piece for both Hour and general damage soaking).
Start with passive abilities like Divine Guardian and Power Word: Barrier, and end with Divine Hymn and Tranquility because these synergise better with Bloodlust.

Speaking of which, there’s a little trick with Bloodlust…

The double-lust trick

You have a dilemma: you really want to give the healers the Bloodlust or Heroism or Time Warp for the end of the fight, but the best time to use it is the very start, where you can line up BL with trinkets, pre-pots and DPS cooldowns.

But you can have your cake and eat it too! Heroic Will takes you into a different realm, so you can’t be affected by buffs or debuffs, including BL and Heroism.

So here’s how to use this to your advantage:

1. Have a countdown timer for pulls. (You already have this though for timing pre-pots, right?)
2. 2 seconds before the pull, have your healers hit Heroic Will
3. Just as the pull is made, pop BL/Heroism/Time Warp. Your healers won’t get the buff but they don’t need it, and crucially they also won’t get the associated debuff
4. At the 5-minute mark, pop a second BL/Heroism/Time Warp so the healers can benefit from it

Spec and Glyphs

The glyphs of Prayer of Healing and Power Word: Barrier are essential. I tend to take the Penance glyph as well, but this is as much for DPS as anything else.

I take an Atonement build for this fight because in the early stages the damage is pretty low so I spend quite a bit of time DPSing. I can put out about 1.8million damage per attempt, which is only 2% of the raid’s damage but makes a huge difference when you’re looking at taking 5-10 valuable seconds off the length of the fight.

Consider taking an extra point in Veiled Shadows so you can get an extra Shadowfiend in, because the default cooldown of 5 minutes makes it tricky to use it twice when you really need it, before you get the Blue buff. See how you go, you may not need it.

Cooldown Usage

PW:B is best used at the start, right at the 5 minute mark, because it doesn’t depend on the Bloodlust being cast immediately. Once the Barrier runs out you should have Bloodlust and can throw Divine Hymn into the mix whenever it fits in your team’s rotation.

Pain Suppression can be used to keep a tank stable if you’re busy regenning mana, but I tend to hold it in case we need a backup for an Hour-soaking team.

Life Grip is fairly useless on this fight, sadly, unless you have an annoying person standing way out at the back and not benefiting from AoE healing.

You’ll only get to use one Hymn of Hope in the fight. The few seconds after an Hour of Twilight are fairly quiet, just warn your fellow healer so they can cover. The same applies to Concentration Potions.

Other Tips

Atonement healing is buffed by the Red buff, and will proc the Green buff as well, so don’t be afraid to use Smite and Holy Fire it if you get either of these buffs. Do look and make sure your raid is getting Atonement heals though, and move them forward or back if not.

The fight doesn’t require much special from you, so as a Discipline Priest your biggest contribution to damage reduction and to the raid comes from using your DPS.
Keep an eye on the raid’s health bars, but go nuts with Smite and Holy Fire in the early days. Just before the first buff is available the damage tends to ramp up and you’ll need to heal for a bit, then you can go back to DPSing because the buff will settle things down for a while.
Shortly before the second buff you’ll probably want to switch to healing full-time, but judge it for yourself.

If you’re not stacking Mastery PoH spam is probably the most effective approach to healing the fight as opposed to heavy PW:S usage. Given this, Discipline Priests benefit roughly equally from Red and Blue (Red doubles PoH and the resulting DA, while Blue doubles the number of PoH casts per unit time), although the Green is less effective because it doesn’t affect Divine Aegis procs. Resto Druids and Holy Priests really shine with the Red buff while Holy Paladins love the Blue buff, so take and then one which is left over and make it work for you. If you’re on Blue, get the Green first of course.

Good luck, and have fun!

NB: This guide will assume you’ve already read my normal Warlord Zon’ozz strategy, or otherwise know the details of the fight on normal mode.

Fight Summary

Moving from normal to heroic mode there are three big changes. The first is that Zon’ozz has an increased health pool but a very tight 6 minute berserk timer, so you need to bounce the ball more times to stack Void Diffusion higher on the boss so you can beat it. The second big difference is that during the Black Blood of Go’rath phase 8 tentacle adds will spawn around the room, and the damage dealt by the Black Blood of Go’rath is multiplied by the number of tentacles still alive. The third is that the Disrupting Shadows debuff he casts on 3 random players in your raid will deal AoE damage and and AoE knockback when dispelled, so you have to take great care with dispelling it.

Let’s go through the more straightforward two first, then we’ll come to the tentacles.

Void Diffusion

As a reminder, every time you bounce the Void of the Unmaking it gains a stack of Void Diffusion, causing it to do 20% more damage on the next bounce. It also gives Zon’ozz a stack of Focused Anger, increasing his physical damage by 20% and his attack speed by 5%. When the Void is allowed to hit Zon’ozz, he gains Void Diffusion instead, increasing all damage he takes by 5%, and his Focused Anger stacks reset. This also triggers the Black Blood phase, which we’ll deal with later.

The Void Diffusion debuff is the key to beating his berserk timer. The debuff lasts 2 minutes, so you are able to stack it up progressively over the course of the fight every time you let the Void hit him. However, in order to beat the berserk you’ll need quite a few stacks. A typical bounce strategy is to go with 7 each time, and 5 on the fourth round. After the fourth set of bounces, you ignore the Black Blood phase adds entirely, pop Bloodlust and hope to burn him down before he reaches Berserk or your healers run out of cooldowns/mana/will to live.

If your DPS is low, you might want to push an extra pair of bounces, either on the first or last sets. 7 bounces shouldn’t require cooldowns to survive (and you’ll need them later, so try and save them) but the damage will be pretty high by the end. 9 may require special treatment, perhaps a PW:B if you have one spare, or you can use tricks like having a Mage with Cauterise or a Shadow Priest with Dispersion solo one bounce.

Disrupting Shadows

On 10-man heroic Zon’ozz will cast this on 3 random players at a time. Before resistances it deals 35,000 Shadow damage per 2s, but the real danger it poses is that when it gets dispelled it deals 60,000 Shadow damage to, and knocks back, everyone within 10 yards.

Because of the significant AoE damage the dispel causes, usually no one should be dispelled before they’ve run out of their cluster. On the other hand, you don’t want too many people running out before the Void reaches your group either or the damage won’t be split widely enough and people are liable to die. So when the Void is on its way to your group, you need to heal the debuffed people through the damage, and only when you’ve split the Void damage should they run out and be dispelled. This will stretch healing, but is manageable; Disc priests can help a lot here with absorbs acting as an extra buffer.

Getting this right is one of the biggest challenges in the encounter. You need to watch the game space as well as your healthbars so you can see where people are and when they’re 10 yards away. It’s also worth coordinating who will do the dispelling so you don’t get two dispels at the same time or waste mana. We assign one healer to the ranged and one to the melee and they dispel their own clusters only.

Black Blood of Go’rath

On normal difficulty, Black Blood of Go’rath is just a raid-wide AoE, you group up and heal through it and get back to bouncing the Void again. On Heroic the Black Blood of Go’rath deals 3,795 Shadow damage per 2 sec for every one of the freshly-spawned 8 tentacle adds (one Claw, two Flails and five Eyes) still alive. What this means is that the AoE damage at the start of the fight is pretty intense, but becomes manageable once 2-3 of the tentacles have died.

The way to deal with this is to have everyone group up at the start of the phase, throw out heavy AoE healing along with a raid cooldown, and have your DPS quickly take out the nearest three tentacles. (I’ll describe our assignments in a moment). The timing is such that you will be able to use 3-minute cooldowns every other Black Blood phase, so plan accordingly; remember that if you’re going to go for a burn after the fourth round of bounces, you’ll need to save your best cooldowns for that phase, which might affect which you choose to start with.

The tentacles spawn in predictable places, which makes planning for them easier:

We split the raid into three teams at this point:

• Left: 2 ranged + 1 healer
• Right: 2 ranged + 1 healer
• Middle: 3 melee

Here’s how we handle this phase:

1. Everyone groups up on the blue marker, right underneath the Claw. The claw needs to be tanked or it’ll do substantial raid-wide AoE Shadow damage and people have a bad habit of getting owned by this.
2. Left group takes out the nearby Flail (spawns on the green triangle marker) while the Right group takes the right-hand nearby Eye (number 4) and the Middle group kills another nearby Eye (number 3). Except for the melee everyone should be stacked up at this point to help with the healing
3. Once these first three tentacles are dead, the Left group heads out to deal with their two assigned Eyes (numbers 1 and 2), the Right group kills their Eye (number 5) and Flail (spawns on the purple diamond marker), and the Middle group switches to the boss, cleaving the Claw down at the same time.

After this phase ends the boss continues to be tanked on the Blue marker while the ranged position shifts to the centre of the room. This positioning then remains until the end of the fight.

Spec and Glyphs

The damage is quite high, so you don’t get the natural lulls you get elsewhere, but Smiting can be very useful for helping your team kill their tentacles in time, and you can build up Evangelism stacks during the early bounces in preparation for either the later few bounces or the beginning of the Black Blood phase.

In terms of Glyphs, it’s again all about the output. Prayer of Healing and Power Word Barrier are must-haves here, and I’d be inclined to take Penance for spot-healing; towards the end of each light phase Zon’ozz will be meleeing the tank pretty hard, and people may also be low from having Disrupting Shadoew dispelled.

Prayer of Mending is a very strong Major glyph here, because of the long periods of sustained raid damage.

Cooldown Usage

PW:B should be alternated with another raid cooldown at the start of each Black Blood phase to keep the raid alive until a couple of tentacles are down. Once everyone’s grouped up you can throw it down and it makes a big difference. I’d recommend saving Divine Hymn for the final burn phase, since you’ll only get one chance to use it and that’s when you’ll need a second cooldown up your sleeve.

Pain Suppression has two uses. First, you can use it to keep the tank alive when Zon’ozz is at >5 stacks of Focused Anger (or whenever else they need it). Especially if your assigned tank healer has to run out because they were unlucky enough to get Disrupting Shadows. The other use for it is if the ranged DPS are slow to return to the middle after killing their tentacles, you can save someone who will find themselves taking a larger share of the damage.

Life Grip can be used to get people to cluster points quickly, but shouldn’t be relied upon.

The Berserk timer on the fight is 7 minutes, so if you want a second Hymn of Hope you’ll have to use it very early in the fight, pretty much just after the pull. You could spam bubbles like crazy before the first bounce and then regen all that mana, but this might not pay off. The best time to pop this, if you’re only going once, is just after everyone’s got back in position after the Black Blood phase, but not when there’s a round of debuffs coming out. The damage is relatively low at this time.

You should be able to get a second Shadowfiend cast in though, so use it early and have it ready for near the end of the fight to allow you to spam like crazy.

Other Tips

Not too much besides what I’ve already touched on. The damage profile is more ramped than spiky, so if you can build up Evangelism before the high-damage portions you’ll be in a strong position. Clever, sparing use of PW:S as a buffer can be really helpful here too, because raid members will be taking some pretty large hits from time to time. In particular, bubbling the people with the debuff is a great way of buying time to allow them to run out and be dispelled safely.

The other thing of note is that Smite and Holy Fire are affected by Zon’ozz’s Void Diffusion buff. Especially in the nuke phase at the end you can get a lot of mileage out of Smite healing. At 45k per Smite your HPS will approximate that of PoH-spamming, plus Atonement stacks DA when it crits and is smart-targeting; not to mention you could also be pushing out 50k+ DPS at a time when, especially on early kills, you’ll be right up against the berserk timer.

NB: This guide will assume you’ve already read my normal Yorsahj strategy, or otherwise know the details of the fight on normal mode.

Fight Summary

The key difference between normal and heroic mode is that Yorsahj spawns four slimes instead of three, dramatically increasing the damage and meaning that you have some more difficult choices to make about which add to kill.

What this means in practice is that you’ll have to deal with the Purple debuff a lot more often, about half of the combinations will include a Purple, and your DPS will need to be much more on the ball to kill the double spawn of adds that comes from a Black/Yellow combination.

There’s also a trick to using the Blue Mana Void to your advantage, which I’ll talk about later.

First though, those combinations. There are in fact only 6 combinations that come up. I’ll list them all, along with a recommended kill target (underlined), and then talk about them all in detail.

These are listed in the order that the current version of DBM reads them out so you can use this as a quick reference if need be. I’ve left Black as white, for obvious reasons.

Purple – Red – Yellow – Black

Purple – Green – Black – Blue

Green – Red – Blue – Black

Green – Yellow – Black – Red

Blue – Black – Purple – Yellow

Blue – Purple – Green – Yellow

Combinations in detail

Purple – Red – Yellow – Black

This is just nasty. Kill the Yellow to keep the damage in check, and then go easy on the heals. You may blow one or two people up, but keep your head and plan ahead and this one is manageable.

If you have a surfeit of cooldowns, you could consider killing Purple, but you’ll need your cooldowns for a later combination so I’d recommend going with Yellow initially and learning to handle it.

The rest of the damage is pretty rough though, so blow those cooldowns and crank out the AoE heals.

Purple – Green – Black – Blue

By contrast, this is one of the easiest combinations to deal with. We kill the Black here to allow ourselves some solid distraction-free DPS time on the boss, but you could go with Green instead for a real healing chillout.

Green – Red – Blue – Black

You have to pick between Red and Green and since you want to stack to kill Black adds, pick Green to kill. There’s a fair amount of raid damage out there, but there’s no Purple to worry about so go to town with the heals and you should be fine.

Green – Yellow – Black – Red

This is another really rough one. Whichever way you slice it you’ll end up with 3 AoE damage abilities to deal with, so you’re going to need to pop some raid cooldowns and AoE heal your heart out to get through it. If there are no cooldowns available pop a Bloodlust instead, which will also help with the Black adds.

You’re pretty much forced to kill the Green so you can stand in to reduce the damage from the Red.

Blue – Black – Purple – Yellow

An easy one. You need to kill the Yellow, because if you don’t the AoE it does will overwhelm you and you can’t heal enough because of the Purple, leaving you with just the damage from the adds to handle, which is manageable.

Blue – Purple – Green – Yellow

Here you’re picking between Yellow and Green to kill, and as with the previous combination you should kill the Yellow for the same reason.

That leaves Green and Purple, which is healable.

Handling the Mana Void

The trouble with the Mana Void is that when you get your mana stolen you really need it back immediately to deal with the silly damage, and because four combinations include a Cobalt Blood you won’t have mana cooldowns available every time. You don’t have time to wait while the Mana Void is taken down from full HP, people will be dead by then.

So, when the first Mana Void spawns you should pop your raid mana cooldowns (Mana Tide, Hymn of Hope) and get by without killing the Mana Void at that time. Then either throw spare DPS on it or assign one person to it specifically while the next slimes are coming in; either way, get it down to around 10% then leave it alone.

Now, when the next Mana Void spawns and you have no mana and no cooldowns left, quickly kill off the old Mana Void for a free full mana bar. DPS the new Mana Void down to 10% again, rinse and repeat.

The advantage of this, despite being a bit more complicated, is that you’re always only a few seconds away from a replenished mana bar whenever you need it.

Deep Corruption

Here’s a full list of abilities that stack Deep Corruption.

Highlights for Discipline Priests:

• Atonement – 1 stack
• Binding Heal – 1 stack to the person you heal. NO STACKS for yourself.
• Divine Hymn – 1 stack per tick (i.e. will wipe your raid)
• Holy Fire (with Atonement) – 1 stack per tick. Do not use if you have atonement.
• Penance – 1 stack for the whole channeled cast (i.e. not 1 per tick)
• Power Word: Shield – 1 stack (even when glyphed)
• Prayer of Healing – 1 stack
• Prayer of Mending – NO STACKS
• Renew – 1 stack on initial application

Binding Heal is a useful spell, because it doesn’t add stacks to you. The downside is that it doesn’t heal for as much as Greater Heal, so if the target is taking big damage and you’re not in danger GH is still favoured.

Do not try and use Atonement here, especially not with Holy Fire. Atonement in general is bad because you can’t plan where it’ll go and it’s fairly weak healing anyway, and especially not Holy Fire because every tick adds another stack.

Penance, Greater Heal and Power Word: Shield are your staples depending on what’s needed most, and because it doesn’t generate stacks, keep PoM bouncing at all times for stack-free healing.

PW:B doesn’t do anything here, so use it if you need it, although it’s better to save it for the evil combinations with 3 AoE damage abilities.

Spec and Glyphs

This fight requires really high output, and is a great example of a time when Archangel shines. You can DPS the boss or the incoming slime to stack Evangelism, then pop it for a healing boost when things get rough later on. It’s also a fantastic boost just after the Mana Void has spawned.

In terms of Glyphs, it’s again all about the output. Prayer of Healing and Power Word Barrier are must-haves here. Pick between PW:S or Penance depending on your usage. I went with PW:S, but there’s a case for both.

Because of no dispels and high raid damage, Prayer of Mending is the Major top pick here.

Cooldown Usage

PW:B and Divine Hymn should be kept for the Yellow – Black – Red combinations. You’ll need them to survive the damage.

Pain Suppression should likewise be use on the nasty AoE healing combinations to keep the tank relatively out of trouble while you focus on the raid. Anything with Yellow up will do that.

Life Grip is useful either to get people in on the Red or out to the incoming slime to get it killed in time.

I’ve touched on Hymn of Hope before, it can be used just after the Mana Void spawns to get your raid some mana back up. Remember that the buff grants a chunk of free mana while it lasts, so even if you have to break off to heal after only a couple of seconds chanelling it’s still worth it. If you’ve got your raid pre-shielded, this ought to buy you enough time to get a few ticks off.
Ideally though, you’d like a non-healing Priest to pop HoH if you have one, so you don’t need to take time out from healing.

I’d suggest saving Shadowfiend for another Mana Void phase. Although you’ll get mana back soon from the Mana Void, there may be times when you need it sooner. Because of the effect of the Mana Void, there’s no point holding more mana than you need throughout the fight, it’s better to have it in reserve.

Other Tips

As I’ve mentioned previously, Archangel from DPSing the adds or boss is very useful for AoE damage phases. Just don’t Holy Fire the boss for a Purple phase, because each tick of Atonement adds a stack of Deep Corruption. he fight on normal mode.

You can prepare for either a Blue or Purple (or both) phase by throwing as many heals and particularly PW:S around the raid as possible before the Deep Corruption buff comes up, to get some stack-free healing and protection out there. You’re going to lose your mana or be limited in your healing ability anyway, so you might as well get a head-start even at high cost.

• 4.3 Dragon Soul Guide for Discipline Priests
• Heroic Ultraxion

NB: This guide will assume you’ve already read my normal Morchok strategy, or otherwise know the details of the fight on normal mode.

Fight Summary

The key difference between normal and heroic mode is that at 90% HP Morchok splits into two clones, one named Morchok and one named Kohcrom, with a shared health pool. Both have the same abilities as on normal mode; Kohcrom does his approximately 6 seconds after Morchok does his, with the exception of the Earthen Vortex/Black Blood of the Earth, which happen simultaneously.
Morchok and Kohcrom both get Furious at 20% HP.

In addition, the Stomp applies a debuff making you take 100% increased physical damage for 10 sec, so you have to split the raid into two teams spread at least 50-60 yards apart (so that one boss’s crystal can’t spawn in the other boss’s Stomp range either) or risk players, especially tanks, being gibbed. There is no Crush Armor, at least!

This splitting of the team requires some thought: in each 5-man team you need a tank plus someone pretty tough to soak the double-hit from the Stomp, which was hitting our Ret Paladin for ~140,000 Physical damage after armour. Rogues can Feint every Stomp, making them excellent candidates, otherwise you’ll need to keep your soaker well topped-off and where possible give them a PW:S too.

On top of that, you need three players to split the damage from the Resonating Crystal. It is unclear whether this targets only ranged players or just ignores the two closest players to the boss, it was merrily targeting someone on the other side of the map rather than picking on the melee DPS soaker if we lost a ranged DPS or healer. You may need to check, and maybe switch an extra melee DPS for a ranged.

A note on composition: we ended up using 4 healers for this encounter, 2 per side. You might be able to lower this eventually but I’d strongly recommend starting with 4 and seeing how you go, even if you get an offspec healer in they’ll be valuable.

Once you have the two teams sorted out, the execution is pretty straightforward, although it is fairly challenging for healers to prioritise healing where it’ll keep people alive – the long-lost art of triage.

There’s a rhythm to the fight, but the most important thing to remember is that every crystal explosion is preceded by a Stomp, so it’s important that when a crystal spawns you wait and soak the Stomp before then running for the crystal. You have roughly 5 seconds to get there, which is easy as long as the tank isn’t miles away from the crystal.
The number one cause of early deaths was people immediately running for the crystal and not splitting the Stomp.

Click to see this in tabular form, if you prefer it that way:

Note that Morchok’s side takes one additional crystal each time, so bear that in mind when planning teams. For example, if your raid has limited mana restoring cooldowns it might be worth putting more on Morchok’s team.

Remember: when a crystal spawns, wait for the next Stomp, then run out to the crystal. You have ~5 seconds to get there, which is plenty of time.

Spec and Glyphs

This fight, on heroic, really rewards damage mitigation. I’d recommend a Soul Warding spec so you can cover your entire group, or at least the three people taking the crystal. Archangel/Atonement is less useful here because Prayer of Healing, with the associated guaranteed Divine Aegis absorption, is a much more valuable tool for recovering from and preventing Stomp and Crystal damage. Given the heavy weight placed on PW:S and PoH it’s probably worth glyphing those.

Cooldown Usage

Morchok takes a little over 6 minutes. To get a second PW:B in, you need to use it between the first and second Black Blood phases, and it will be available again during the Furious stage.

Pain Suppression should be used to support your tank and your Stomp soaker during the enrage, when they’ll be taking extra damage from the stomp and may not be able to rotate cooldowns for every one. Earlier in the fight, it can be handy if one person on your team is too low before a damage spike.

Life Grip can save someone’s bacon if they’re slow to run out to get away from the Black Blood or especially if they’re too slow getting in for a crystal.

Finally, the Black Blood phase is a good time to use Hymn of Hope, since there’s no damage caused while you’re safely behind the pillars. Shadowfiend is also safe from the Black Blood because it’s AoE damage, yet Morchok himself can still take damage.

Other Tips

Discipline shines on this fight, because there’s spaced-out damage spikes.

Make sure you PW:S the Stomp soaker and use a few casts of PoH to stack Divine Aegis before the Stomp, then while running to the crystal you can get PW:S on the three people that will take the damage. Once you’re back by the boss and in the ~8 sec lull before the next Stomp, bring everyone back up with Binding Heal and PoH in preparation for the next round.

Binding Heal is a real gift on this fight too, it really helps keep you alive while healing other people and it’s a nice quick cast for triage purposes.

So, what’s in store for us Discipline Priests in 4.3?

The New Outfit

The Vestments of Dying Light are available in tasteful gold, blue or red, depending on your raiding tier of choice.

After my initial “WTF!” reaction, I sat and looked at the set for a while and it really grew on me. There’s definitely something Priestly about it, but not the gentle, friendly image of a Priest but instead has us putting our serious face on (literally), filling ourselves with smouldering, barely-restrained power of the Light and getting prepared for the grave business of taking on Deathwing.

How badass it’ll manage to look on a gnome though is anyone’s guess…

Set Bonuses

First, the bonuses themselves:

Healer, 2P — After using Power Infusion or Divine Hymn, the mana cost of your healing spells is reduced by 25% for 23 sec.)

Healer, 4P — Your Power Word: Shield has a 10% chance to absorb 100% additional damage and increase the mana granted by Rapture by 100%, and the duration of your Holy Word abilities is increased by 33%.

So, let’s take a look in detail.

The 2-piece bonus is handy, but also a bit of a head-scratcher. It’s been pointed out on EJ and elsewhere that this presents Disc Priests with something of a question: should we be casting Power Infusion on cooldown just for the mana reduction, or should we be saving it for when we actually need the throughput.

PI has a split personality already though, with the throughput and mana saving components. I find myself mostly using it as a throughput cooldown, popping it when I shift to the healing-intensive part of a fight, and since that’s where the expensive spells (PW:S, FH, PoH) hang out, I figure I’m probably getting a good benefit from it.

The thing to remember is to make sure you’re using it vaguely sensibly, i.e. when you’re going to be healing hard, and make sure you get as many uses as practical and don’t leave it languishing on cooldown unless you know there’ll be a point where it’s vital.

It’s also attached to Divine Hymn, which works for the same reasons – we’ll be casting DH when things are getting tight, and this mana cost reduction will help offset the costs of healing people up afterwards.

The 4-piece bonus for Discipline is a bit of a conundrum. The way it works seems to be that one in every 10 times you cast PW:S (on average), it’ll absorb twice as much and give a double-sized Rapture proc when it breaks.

This in itself is a decent bonus: Disc Priests bubble someone at least every 12-15s for Rapture, more often if you’re tank-healing, and in the Dragon Soul you might well find yourself with moments where throwing out bubbles more frequently pays off, so as long as you’re using PW:S regularly you should get the benefit. You will have to be careful when using PW:S as a pure raid-healing spell though, because a larger bubble is less likely to be totally consumed and possibly end up preventing what might otherwise have turned into a Rapture proc. It’s fine for tanks, but on the raid you may want to think about where you PW:S to make sure it will be fully absorbed. Depending on your Mastery you may need a hit well over the 60k mark to burst it.

The Patch

As usual, very little for Priests in the patch notes, although what there is is definitely worth a look:

Divine Hymn now affects 5 targets, up from 3.

Discipline
Atonement will now account for the target enemy’s combat reach when calculating proper range, enabling it to be used on large creatures such as Ragnaros and Ala’kir.
Divine Aegis has a new spell effect.

Holy
Spirit of Redemption has been rebuilt to address a few functionality issues and make it more responsive. Spirit of Redemption otherwise remains unchanged.
State of Mind has been redesigned and is now called Heavenly Voice. Heavenly Voice increases the healing done by Divine Hymn by 50/100%, and reduces the cooldown of Divine Hymn by 2.5/5 minutes.
Guardian Spirit’s healing bonus has been increased to 60%, up from 40%.
Holy Word: Serenity now has a cooldown of 10 seconds, down from 15 seconds.

Glyphs
Glyph of Circle of Healing now also increases the mana cost of Circle of Healing by 20%.

For Disc, the big change of course is the new Divine Aegis bubble! Have some videos:

On the left is the “old DA” applying and then persisting, and my “new DA” video from the PTR is on the right. Unfortunately the old DA procced from a Glyph of PW:S crit, so there’s the PW:S graphic in there to confuse things, but the effect is clear enough.

And here’s the proc effects in close-up, old on the left, new on the right:

That new still is so damn tasty I’m using it as my avatar just about everywhere I can. It looks so sweet!

The old Divine Aegis used to wrap beams of light around the player as the bubble appeared, while the new one sort of expands a rainbow-coloured soap-bubble effect instead. I can see how the old effect could end up looking very flashy and noisy on screen, whereas the new one, while still really cool and colourful, has less point movement and is less bright overall.

I was really thrilled to be getting something all-new, until I noticed that this same soap-bubble effect procs when a Mage uses Arcane Blast (it’s Arcane something anyway) on a mob. Still, it looks damn good, even if it is borrowed. It’ll look better on us anyway!

OK, more seriously, the Atonement change. Finally, two tiers later, Atonement works off the boss’s hitbox rather than the boss’s centre. I presume there must have been something big and scary and technical preventing this change from making it in earlier, or perhaps Ragnaros brought it to a head in a way that Al’Akir didn’t manage to. Anyway, good news.

Finally for us, a small buff to Divine Hymn for all Priests, with it healing 5 targets rather than 3. That should help its throughput for both specs, although Holy gets a much improved version as their new raid cooldown: double the healing and a 3-minute cooldown means Holy has its own Tranquility to play with.

My initial reaction was (of course) to get all angsty and bitter that Holy gets buffed and Disc doesn’t, but actually there have been several fights I’ve ended up staying Disc because of the combination of PW:Barrier and an AoE pulse. Now that Holy gets a powerful raid cooldown of its own the dual-spec option opens right back up again, and that can only be a good thing for the class. It’s no nerf to Disc, just a rebalancing of the specs in the sorts of bursty fights where Disc currently dominates because of a single spell. GC agrees.

Just think of it as another powerful raid cooldown for the rotation and enjoy it.

Other Healers

We need to know how our other healing friends will be changing this patch too, so we know how to work well with them and play to our respective strengths.

Shaman are staying more-or-less the same in terms of playstyle, although they will be getting a buff to their Ancestral Healing talent:

Ancestral Healing now also causes the shaman’s heals to increase the target’s maximum health by 5/10% of the amount healed, up to a maximum of 10% of the target’s maximum health, for 15 seconds. This effect does not stack if multiple Restoration shaman are present, and does not apply to heals from procs.

The wording suggests that this doesn’t need a crit and is a bonus attached to the Ancestral Healing talent, not the buff, so it shouldn’t matter whether the tank has Ancestral Fortitude (the damage reduction buff) or Inspiration on them.

Your Shaman should try to keep up the Ancestral Vigor buff (the 10% HP buff this creates) on tanks. On the PTR, when it fell off it dropped the player’s maximum HP back down again, but also reduced their current HP by the same amount, which was certainly not ideal because it meant that extra healing done while the buff was up was lost again when it expired; hopefully this has been fixed before going live.

Druids don’t have much new this time, although they are getting small nerfs to Wild Growth, they shouldn’t change how they heal much.

Wild Growth healing has been reduced by 20%.
Glyph of Wild Growth now also increases the cooldown on Wild Growth by 2 seconds.

Paladins are getting a revamped version of Holy Radiance:

Holy Radiance now has a 3.0-second cast time, no cooldown, and requires a player target. That target is imbued with Holy Radiance, which heals them and all group members within 10 yards instantly, and continues to heal them by a smaller amount every 1 second for 3 seconds.

This, combined with Light of Dawn, means they will be capable of some pretty loopy (albeit costly) burst AoE numbers when the raid is all stacked up, so bear this in mind when considering healing assignments. It might be that we Discipline Priests shift more onto tank-healing when the fight mechanics favour the new HR, and swap with our Paladin brethren when the raid is more spread out.
Paladins are also getting a small mana nerf because Judgement will no longer return 15% of base mana. This shouldn’t be too much of a problem, and it’ll free up a lot more GCDs for them.
