What repeats?

  1. 1. Phase 1: Fury of the Serpent Mother · PullCarry eggs, dodge Caustic Waves, soak Spectral Coils, then burn the first damage amp.
  2. 2. Phase 2: Children of the Doomscale · After the first Rage of the Shackled, when she submergesTwo groups cross to side platforms, kill Wardens and feed eggs to the Doomscale Cauldron.
  3. 3. Intermission: The Shattering · After Phase 2Groups run between spectral tails soaking Spectral Coils; the platform breaks into 4.
  4. 4. Phase 3: Ula’tek’s Ascension · After the platform shatters into 4The floor shrinks as platforms break; Serpent’s Bite soaks and Shrieker adds.

The loop: Phase 1 runs Spectral Coils, Caustic Waves, submerge and resurface, an egg wave, the same combo again, then Rage of the Shackled.

Next three

  • Caustic Waves — Run to the side opposite the wing she draws back and dodge the wave lines.
  • Mother’s Wrath — The tank stays in melee for it; swap on high Stone Venom stacks, during a cast.
  • Gore Rattle — Tanks keep someone in tail range so it always has a target.

What happens when? · Phase 1: Fury of the Serpent Mother

Blightscale Spawn: Anyone can carry eggs; keep eggs and carriers away from anything green.

When do tanks swap?

Swap during a wave or another cast, never on open GCDs, and on high Stone Venom stacks.

  • Cover both her melee and her tail at all times.
  • Swap during a wave or another cast, never on open GCDs; swap on high Stone Venom stacks.
  • Be at the bubble-marked resurface spot right away so she never sits idle.
  • Phase 3: taunt each Blightscale Shrieker so it dies quickly.

Where do I stand?

  1. Split into two equal groups before the pull: Coils soaks and Phase 2 sides.
  2. Phase 2: cross with grips and rescues, don’t swim, and keep the Warlock gate for the return.
  3. Intermission: stand to the side, away from the middle, as the platform shatters.
  4. Phase 3: melee and tanks on the boss platform; ranged and healers to its left, counter-clockwise.
  5. If close at the end, jumping into the water just before the last break buys a few seconds.

Setup on Heroic: 2 tanks · 5 healers · 13 DPS. From Method’s guide, 2026-08-30.

Where the guide disagrees

  • Is the guide current?It was last updated on 30 August. Blizzard eased Ula’tek on 6 October (Spectral Coils −20%, stage 3 adds −20% health), after it.

What does each role do?

Tanks
  • Cover both her melee and her tail at all times.
  • Swap during a wave or another cast, never on open GCDs; swap on high Stone Venom stacks.
  • Be at the bubble-marked resurface spot right away so she never sits idle.
  • Phase 3: taunt each Blightscale Shrieker so it dies quickly.
Healers
  • Necrotic Vapors stacks raid Nature damage that keeps growing all fight.
  • Phase 3 Serpent’s Bite: healers soak together, often with close-range specs.
  • Save survival cooldowns for the second platform break, the hardest moment.
Damage dealers
  • Hero and all cooldowns on the Venomous Heart during the first Rage of the Shackled.
  • Phase 2: kill the Warden, then the Weakened Doomscale; interrupt its Anguished Cry.
  • Drag hatched Rawlings onto the boss for cleave; otherwise ignore them.
  • On the last platform, race the enrage before she breaks the final piece.
