Chimaerus Raid Guide in Dreamrift for Midnight Season 1

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.

• 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:
  1. 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.
  2. Colossal Horror (Tank Add): This is the priority to kill in this phase. If it stays alive for too long, your tank may die.
  3. Haunting Essences (Casters): Interrupt Fearsome Cry as a priority. Spare interrupts should stop Essence Bolt casts. Cleave these down. These adds appear from the first intermission onwards.
  4. Swarming Shades (Small Adds): Cleave these down.
  5. 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:
  1. 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.
  2. Ensure all adds are tanked on the opposite side of the room, away from the boss.
  3. 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.

• 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.

• Tank Mechanics:
  1. Keep the boss away from adds that have been sent upstairs.
  2. Keep the boss faced away from other players.
  3. Rending Tear will apply a bleed to every player hit and knock them back.

• 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.
• Ensure all adds are dead before the boss lands with Ravenous Dive, as they will be consumed and you will wipe.
• A good general movement rule is to move left facing the boss and always reset in the middle after the adds have spawned.

• Phase 1 - Consuming Miasma:
  1. This debuff puts a circle around the player, indicating which pools they will clear once dispelled.
  2. 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.
  3. 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.

• Intermission:
  1. Ravenous Dive will no longer clear pools on the ground.
  2. The only way to clear space in the room is with Consuming Miasma.

• 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.

• 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.

• For this fight on Mythic the raid will play on one side of the room each. This is to easily handle where people are positioned and prevent any deaths from Dissonance.
• The positions and markers on the below image is a good refence to work from.
• You will notice there are two warlock gateways. The intention here is that the tank will soak on top of the marker and the group can instantly gateway to avoid being knocked in the air and falling to the ground. This will gain you around 2 seconds of additional DPS time.

• Dissonance
  1. This mechanic prevents you from standing on or near other players who are downstairs while you are upstairs and vice versa.
  2. For this reason we divide the room in two and have players play with their group.
  3. If you get swapped from Rift Madness then you play with the other group until your team has returned.

• Rift Madness
  1. Two players who are downstairs will be affected with this debuff. If they are not soaked by someone upstairs they will be permanently feared and die.
  2. It always goes on 1 Healer and 1 DPS. Therefore you should have 1 Healer in each team to swap (ideally not the healer that is ramping) and 1 DPS (a highly mobile ranged DPS is preferable).
  3. The two players who are targeted should go to their markers instantly while staying on their side of the room to prevent cleaving other people.
  4. The two upstairs players will then stand in the circle, get knocked in the air and swap phases.
  5. This does not apply a debuff so you can still soak with your team on the next cycle.
  6. You can avoid taking damage from Dissonance by standing on the edge of the circle as the upstairs player.

• Intermission:
  1. Another Mythic change is that Team 1 will go into the downstairs phase again for the Intermission. They will need to soak on their tank.
  2. Once you are downstairs be careful to not run over the other group. To easily handle this a good recommendation is to stand either side of the Cross marker as shown in the raidplan image above to bait the breath in the centre and then go to your sides.
  3. Each team have to deal with adds as they have in Heroic.
  4. The Fearsome Cry casts are very fast and need to be interrupted. Any missed interrupts will result in a wipe.
  5. Warlocks should use Curse of the Satyr to make it easier to interrupt and Death Knights should Death Grip the casts into their team ASAP.

• Optimisation:
  1. You can let the adds get quite close to the boss just before the Consume cast starts at 100 Energy. Once the cast has started the adds will be stunned and cannot be auto consumed by the boss. This means that if they are on ~30% HP, you can safely cleave them down and finish them off before the end of the cast. This will result in more boss DPS.
  2. If your Boss HP is ~25% on the second Alndust Upheaval on the second Phase 1 cycle. Just send the tank in by themselves and let them die. The remaining 19 players can kill the boss before the Consume Cast.
  3. Two Death Knights and two Warlocks make this fight significantly easier.
