The Dreamrift

Raid guide · Patch 12.0 · Normal / Heroic / Mythic

All raids

The Dreamrift is a single-boss raid where the Emerald Dream bleeds into reality. Chimaerus splits the raid into an upstairs group (boss + adds from below) and a downstairs group (soak Alndust Upheaval, kill shielded adds). Adds reaching Chimaerus grant +100% damage per stack — upstairs DPS treats every add as a wipe timer.

  • No trash — rebuff at the arena entrance and confirm upstairs/downstairs assignments.
  • Split raid evenly: 1 tank, half healers, half DPS per group before pull.
  • Place markers: upstairs boss corner, downstairs add tank corner, Alndust soak spot.
  • Heroism on third Lucidity window (~30%), not on pull.
  • Mythic: warlock gateways at soak marker save 2 seconds knockback time.
  • Assign a 'Dream Warden' caller who announces upstairs vs downstairs phase.
12.0

Chimaerus the Undreamt God

Split-raid encounter: downstairs soaks Alndust Upheaval, breaks absorb shields on adds, sends them upstairs where they must die before reaching Chimaerus. At 100 energy he consumes living adds. Intermission: kill Manifestations during Corrupted Devastation lines. Heroic adds Consuming Miasma to clear add pools.

The fight, in order

  1. 1

    Split pull

    Downstairs soaks Alndust. Upstairs tanks boss at edge.

    Know your group before pull — upstairs or downstairs, you stay with your group. Downstairs stacks on the soak marker and soaks Alndust Upheaval together to enter the lower phase. Upstairs edge-tanks Chimaerus facing away from the raid and platform edge.

    Everyone
  2. 2

    Add pipeline

    Down breaks shields → upstairs kills before boss.

    Downstairs: break absorb shields on adds, kill Colossal Horror first, keep adds far from boss. Upstairs: swap to EVERY add the moment it appears — adds are priority #1. If any add reaches Chimaerus, he gains +100% damage; two adds is usually a wipe.

    Damage
  3. 3

    100 energy

    Consume stuns living adds — finish low adds during cast.

    Kill all adds before 100 energy or Chimaerus consumes them for +100% damage each. Optimization: let adds get to ~30% before Consume starts — cast stuns them for free cleave during channel. Interrupt Fearsome Cry on rotation with zero gaps.

    Damage
  4. 4

    Intermission

    Dodge Corrupted Devastation. Kill Manifestations.

    Move left facing the boss during Corrupted Devastation flight lines. Kill every Manifestation before Ravenous Dive — living Manifestations at landing get consumed for a massive boss buff. Reset to middle after spawns; all dead before dive finishes.

    Everyone
  5. 5

    Burn windows

    After intermission. Lust on third cycle ~30%.

    Heroism on third Lucidity window around 30%, not on pull. Upstairs DPS burns boss during recovery after intermission; never pad boss while adds are alive. Heroic: Consuming Miasma carriers run to pool clusters and get dispelled to clear ground.

    Damage

Do this

  1. Know your group before pull — upstairs or downstairs. You stay with your group.
  2. Downstairs: soak Alndust Upheaval, break add absorb shields, kill Colossal Horror first.
  3. Upstairs: boss is edge-tanked; swap to EVERY add the moment it appears — adds are priority #1.
  4. If any add reaches Chimaerus, he gains +100% damage — two adds is usually a wipe.
  5. Interrupt Haunting Essence Fearsome Cry — spare kicks on Essence Bolt.
  6. Intermission: move left facing boss, kill all Manifestations before Ravenous Dive.
  7. Heroic: Consuming Miasma carriers run to pool clusters and get dispelled to clear ground.

Not this

  • Upstairs DPS padding boss while adds are alive — Consume at 100 energy eats them.
  • Downstairs adds spawning near boss — tank holds opposite side of room.
  • Missing Fearsome Cry interrupt — fear into pool or off platform.
  • Intermission Manifestations alive at landing — consumed for massive boss buff.
  • Heroic: standing in add pools without Consuming Miasma clear — room fills.
  • On Mythic: Dissonance — upstairs player near downstairs player (or vice versa) kills both.
On Heroic:
  • Consuming Miasma required to clear pools — assign carriers.
  • Ravenous Dive no longer clears pools.
  • Fearsome Cry faster — tighter interrupt rotation.

Mechanics

  • Add
  • Tank
  • Healer
  • Damage
  • Get out
  • Stand here
Soak together
  1. The downstairs group stacks on the soak marker.
  2. Soak it together.
  3. The knockback throws the group to the adds.

Alndust Upheaval

Downstairs group stacks on soak marker. Soak together — you get knocked to adds. Mythic: gateway immediately after soak to save DPS time.

Downstairs group soaks to enter the lower phase. Knockback into add arena.

Everyone
Break, then kill
  1. Downstairs breaks the absorb shield on the add.
  2. The broken add teleports upstairs.
  3. Upstairs kills it the moment it appears.

Absorb Shield Adds

Downstairs: break shield then kill. Colossal Horror is first priority — it hurts your tank. Keep adds far from boss. Upstairs: kill the moment they appear.

Every downstairs add has an absorb shield. Broken adds teleport upstairs.

Damage
Burn it first
  1. The downstairs tank holds the Horror where it spawns.
  2. Damage dealers kill it before the other adds.
  3. The tank uses a defensive as it gets low.

Colossal Horror

Downstairs tank holds Horror where it spawns. DPS burn it first. Tank uses defensives as it gets low.

Downstairs tank add; damage ramps the longer it lives.

TankDamage
Kick every Cry
  1. Haunting Essences cast Fearsome Cry, a fear.
  2. A different player interrupts each cast. Never miss one.
  3. Spare kicks go on Essence Bolt.

Haunting Essence

Interrupt Fearsome Cry on rotation — never miss. Extra kicks on Essence Bolt. Cleave essences down.

Caster adds with Fearsome Cry (fear) and Essence Bolt.

Damage
Adds dead first
  1. Chimaerus fills toward 100 energy.
  2. The Consume cast stuns any add still alive.
  3. Kill every add before he eats it.

Consume

Kill all adds before 100 energy. Optimization: let adds get to ~30% before Consume starts — cast stuns them for free cleave during channel.

At 100 energy Chimaerus consumes living adds for +100% damage each.

Call it: Mythic: at ~25% boss HP send downstairs tank alone to die — 19 players can burn boss before Consume.

Damage
Face it away
  1. The tank points the boss away from the raid and the edge.
  2. The frontal bleeds and knocks back anyone it hits.
  3. Melee stack at the side of the boss.

Rending Tear

Upstairs tank faces boss away from raid and platform edge. Melee stack on safe hip.

Upstairs frontal bleed + knockback on anyone hit.

Tank
Left, then kill
  1. Flight lines cross the room and spawn Manifestations.
  2. Move left, facing the boss, out of the line.
  3. Kill every Manifestation before Ravenous Dive.

Corrupted Devastation

Move left facing boss. Kill every Manifestation. Reset to middle after spawns. All dead before Ravenous Dive.

Intermission: flight lines across room spawn Manifestations.

Everyone
Clear the pools
  1. Your circle shows which pool pieces a dispel will clear.
  2. Run it beside a cluster of add pools.
  3. Get dispelled: every piece under the circle clears.

Consuming Miasma

Run to add pool clusters upstairs. Get dispelled — any pool segment under your circle clears. Not standing in pools required.

Heroic+: circle on player shows which pool zones clear on dispel.

Your job

Tank

  • Upstairs: edge-tank Chimaerus, face away, never near landing adds.
  • Downstairs: hold Colossal Horror opposite boss; funnel adds to you.
  • Don't pick up adds mid-room — let them come to you.
  • Mythic intermission: downstairs team soaks again — coordinate cross marker.

Healer

  • Split evenly between groups — both need dedicated healer coverage.
  • Downstairs: ramp when Colossal Horror is low HP.
  • Heroic: dispel Consuming Miasma on pool clusters on call.
  • Mythic: one healer per side for Rift Madness rotation.

Damage

  • Upstairs: adds over boss — always. Call 'add up' the instant one spawns.
  • Downstairs: Colossal Horror → Haunting Essence → Swarming Shades.
  • Interrupt Fearsome Cry with zero gaps.
  • Intermission: kill Manifestations, ignore boss.
From the Encounter JournalBlizzard's own notes and ability list for Chimaerus the Undreamt God

Chimaerus wrenches its enemies into the Rift during Alndust Upheaval where they must contend with aberrant Manifestations shielded by Alnshroud.
