Chimaerus Raid Guide
Mechanic Breakdown (Normal/Heroic)
Before you pull the boss, split the raid into two evenly split groups with 1 Tank, half of your healers, and enough DPS in each.
One group will soak
Alndust Upheaval and go downstairs. The other group will
stay upstairs and deal with Chimaerus.
Phase 1 (Alndust Group/Downstairs Group):
- After you have soaked
Alndust Upheaval, you will be knocked into the air
and should look for where the adds have spawned. - You have a limited amount of time in this phase. Ensure you are prepared to deal damage to adds by pooling resources or saving cooldowns.
- Every time an add is sent upstairs they will leave a large pool on the ground.
- Adds:
- Every add will have an absorb shield on them. Once it has been destroyed, they will leave this Phase and the upstairs group has to kill them before they reach the boss.
- Colossal Horror (Tank Add): This is the priority to kill in this phase. If it stays alive for too long, your tank may die.
- Haunting Essences (Casters): Interrupt
Fearsome Cry as a priority.
Spare interrupts should stop
Essence Bolt casts. Cleave these down. - Swarming Shades (Small Adds): Cleave these down.
- When the adds go upstairs they will walk slowly towards the boss. If they reach the boss it will gain a stacking +100% damage dealt buff. At 100 Energy the boss will consume any add that is still alive.
- Tank Mechanics:
- Your role in this part of the boss fight is to tank the Colossal Horror. Tank it where it stands, and let adds slowly funnel towards you, rather than trying to pick them up.
- Ensure all adds are tanked on the opposite side of the room, away from the boss.
- The Colossal Horror will deal more damage the longer it is alive. Utilise defensive cooldowns as needed once it starts to get low on health.
Phase 1 (Upstairs Group):
- Keep the boss on one side of the room. Do not tank it in the middle.
- When adds spawn from the downstairs group, swap to them ASAP. If any of them reach the boss, you will wipe immediately.
Consuming Miasma:
- This debuff puts a circle around the player, indicating which pools they will clear once dispelled.
- If you have this debuff, run to the areas of the room that have pools on the ground, which were spawned by the adds that were sent upstairs.
- Once you are dispelled, all pools in the area will be cleared. You do not need to stand inside of the pools. If any area of your circle covers a pool segment, it will get cleared.
- Tank Mechanics:
- Keep the boss away from adds that have been sent upstairs.
- Keep the boss faced away from other players.
Rending Tear will apply a bleed to every player hit and knock them back.
Intermission:
- The boss will fly up into the air and cast
Corrupted Devastation in lines
across the room. - Manifestations will spawn from these areas. Your job is to kill them while avoiding the flight paths.
- Similar to Phase 1, if you have
Consuming Miasma, run towards a pool on the
ground and get dispelled. - Ensure all adds are dead before the boss lands with
Ravenous Dive, as they
will be consumed and you will wipe.
Heroic Changes:
- Phase 1:
Consuming Miasma will now do AoE damage and a knockback if anyone is inside
of it once dispelled.
- Intermission:
Ravenous Dive will no longer clear pools on the ground.
Quick TLDR Guide
Phase 1:
- The raid is split into two groups, an Upstairs Group, and a Downstairs Group (Soaking
Alndust Upheaval). - If you are downstairs: Destroy absorb shields on adds before your timer expires. Make sure they are away from the boss. Interrupt the Haunting Essence adds.
- If you are upstairs: Kill adds as soon as they appear. They are your number one priority.
- If you have
Consuming Miasma, run towards a pool on the ground and get
dispelled. - Tanks: Upstairs tank: Keep the boss towards the edge of the room and avoid
being knocked off the platform with
Rending Tear. - Tanks: Downstairs tank: Keep the adds on the opposite side of the room from the boss.
Intermission:
- Avoid the
Corrupted Devastation flight lines on the ground. - Kill all adds.
- If you have
Consuming Miasma, run towards a pool on the ground and get dispelled.
