Disclaimer: This is the heroic version of the fight, and I will only be going into changes and the strategy specific to heroic mode. For a full list of abilities and general strategies, please check out the normal mode guide.
Introduction: The Uldum of Dragon Soul. All the cinemas in the world cannot save this fight from being the hardest boring fight this tier.
Difficulty: 5/5: While the current iteration of this fight is nowhere near as hard as when it was released in December, this fight still requires a lot of patience, moments of very high burst DPS, timed CDs, large amounts of healing, dispelling, raid coordination, and a pretty high desire to get it dead. Grind on!
Comp and Stats:
Tanks: 2
Healers: 3
DPS: 5 (burst specs are nice)
Burning Tendon: 10.2M
Hideous Amalgamation: 9.36M
Corruption: 761k
Corrupted Blood: 275k
Enrage: Not really, but you have to kill the Tendons within 2 lifts.
Heroic Changes:
- Lots more health and damage!
- Grasping Tendrils do about twice as much damage.
- Grasping Tendrils now slow movement 50% instead of 35%
- Searing Plasma deals 12,000 damage every 10 seconds and will absorb 280,000 healing.
- Fiery Grip now deals 90,000 damage every 3 seconds.
- Superheated Nucleus now does 30,000 every 3 seconds, double that of normal.
- Burst will now do about 22,500 damage per blood killed.
- Health info is above.
- Degradation – A stacking debuff that applies to the entire raid each time a Hideous Amalgamation is killed. Each stack reduces the target’s maximum health by 5%. This cannot be dispelled and lasts throughout the encounter. This will not apply if they are flung off during a barrel roll, just if they are killed.
- Blood Corruption
- Blood Corruption: Death – Dispellable debuff that will be placed by a Hideous Amalgamation on random raiders. This needs to be dispelled within 15 seconds or it will immediately wipe the raid.
- Blood Corruption: Earth – Eventually dispelling BC: D enough will lead to it becoming this. You want to leave this on the player that gets it as they will receive the buff Blood of Neltharion when the duration is up. Blood of Neltharion will reduce damage by 20% and can stack two times.
- Quick Note: Even though the Dungeon Journal says it can corrupt itself back to Blood Corruption: Death, it will not. (Thanks for the tip suggestion Gene!)
Setup:
Intro: Just like on normal you will begin by parachuting down onto Deathwing’s back. Make sure you cancel your parachute so you can begin that much quicker.
Specs: DPS should spec into what will give them the greatest amount of burst DPS if the tendons are giving the raid the most issue. However, most good DPS should be able to get the tendons down to at least 40%, so sometimes spec’ing into something to deal with the Amalg. Spec’s such as Arcane and Subtlety still reign supreme on the tendons however.
DPS Trinket: All DPS should get their on-use valor trinket for this fight and use it every plate lift.
Directions: All directions below will be assuming you are facing Deathwing’s head.
Bloods:
Bloods will begin spawning every 8 seconds. This will decrease for every Amalgamation killed. At the end, that means a new blood will be spawning every 3 seconds. This does not count blood residue reaching the Corruption pit.
Plate One:
Parachuting In: Have your melee kill the Corruptions on the right first, ranged kill the left two corruptions with melee joining them on the left. The tanks should pick up the 4 Hideous Amalgamations and be on the right side of spine, with the rest of the raid on the left.
Stacking the Buff: The reason for getting four amalgs and having the raid away from the tanks is for Blood Corruption. On dispelling Blood Corruption: Death it will favor bouncing to someone on the other side of the spine. This allows you to game the targets making it possible to quickly stack the tanks with Blood Corruption: Earth. You want at least your Blood tank to get two stacks of this, and if possible both tanks at two stacks. This reduces their damage by 40%, making surviving the late stage of this fight much more manageable. During this time, no one should be attacking any Bloods or Amalgs, you can DPS the 5th corruption, but do not kill it.
Barrel Roll: Once tanks are stacked with the buff, have your raid collapse on one of the left corruption holes and roll Deathwing. A raid-wide CD like SLT should be used here. Proceed then to continue the fight as normal at this point, killing the corruption and picking up the amalgamation.
Positioning: Have your blood tank pull all bloods up to the plate. A survival hunter, or warlock should be killing bloods full time, but also damaging the Amalg as well. The Amalg tank should position the Amalg close to the plate as well, but behind the blood tank. ALL OTHER RAIDERS SHOULD STACK UP ON THE AMALG TANK! This is paramount in the later plates.
Fiery Grip Timing and the Amalgamation: As you burn down the Amalg you will continue to get Fiery Grip, Bloods, the healing debuff, etc. After the first Fiery Grip goes off, the Amalg should be getting well below half-health. You want to start stacking his Absorb Blood when the second Fiery Grip countdown is at about 10-12 seconds left. The Amalg should be at 10% or lower HP when reaching 9 stacks, and the grip timer should be under 10 seconds at this point.
This allows for the rhythm to be: Stack Amalg to 9->Superheated->Kill Amalg->Nuclear Blast->Fiery Grip->Plate lifts. The grip should be interrupted before the tendon comes out. If Fiery Grip is cast during a tendon burn phase, you are doing it wrong.
Nine Stacks: Coordinate raid CDs like AM, SLT, etc. during Superheated. This should be for every single lift.
Tendon Burning: Everyone needs to be right up on the tendon when it comes up, stacking for easier healing. Tanks should also be helping out here with the tendon as there should not be much going on (at least until the last plate). The first plate lift should be done with no Heroism or combat potions. Use your CDs like VP trinket and those that are up every time. If they are not up, use the larger CDs on lifts where you will not have heroism or a combat potion.
Make a macro! DPS and Tanks should all have a keybound macro for the tendon. Here is one I use if I am Combat:
#showtooltip Kiroptyric Sigil
/tar boss2
/startattack
/cast [@focus] Tricks of the Trade
/use Kiroptyric Sigil
/cast Adrenaline Rush
/cast Sinister Strike
The key takeaways here are /tar boss2 (This will target the tendon as soon as it is tagetable, but will target something else until it becomes available. /startattack begins my melee swings, and the rest is to spam cast all my buffs. Everyone should have a similar suitable macro to begin DPS immediately.
Second Lift: Provided you burned through the tendon well enough, you just have to repeat the same process again.
Plate Two:
Transition from Plate One: Kill the Corruptions on the side that has two of them. At this point you will likely have a chunk of residue where the first place was. Once the corruptions are dead the leader should take note of where the most blood residue is, and call for the raid to get ready to stack on that side to roll deathwing. Make sure your Amalgamation tank has enough time to pick up the two amalgs before stacking the raid.
When the call is made, everyone should stack in the corruption hole to get secured except the Amalg tank. He should wait until there is just a couple seconds left before barrel roll and at that point run the amalgs through residue and get secure himself.
This is important because the amalgs will likely get 9 stacks here and if you time it right, they will absorb all that blood and get tossed off before doing any ticks of their Superheated ticks.
Rinse and Repeat: Begin the grind again, but this time with more bloods spawning and being killed by your hunter/lock/designated DPS. On the first lift of the second plate Combat Potions should be used.
Plate Three:
Transition: This can easily be one of the hardest parts of the fight because you will have a much larger amount of blood and the degradation debuff. The same absorb strategy should be used as before, but extra care should be used to only absorb right before the roll. Pop additional bloods before the roll if you can handle it, but watch raid HP.
First Lift: Same as before, kill the amalg, stack amalg on bloods, and DPS the tendon.
Second Lift: At this point there will be too many bloods to kill. The blood tank will need to start kiting the bloods around. This will be a very stressful point for all players, but towards the end of the amalg burn, Heroism should be used to push through it as fast as possible.
Some key things to remember: Make sure you have enough residue to stack the amalg to nine, make sure people do not tunnel vision and kill the amalg before nine, make sure all raiders except the blood tank are stacked on the amalg tank, and make sure Heroism is used around the time the amalg tank is going to stack the amalg to nine.
Once the amalg is at nine stacks, blow your collective defensive and offensive CD load and blow the fuck out of the tendon. It is unlikely the blood tank will be able to help this time around, so focus and push hard.
