What repeats?

  1. 1. Council · Pull, and again after each intermissionTwo golems tanked 40+ yards apart, half the raid on each, health kept even.
  2. 2. Intermission: Vitriolic Stasis · 100 energyBoth golems meet in the middle for 30 seconds while every player solves Helical Toxins.

The loop: Split council until 100 energy → Vitriolic Stasis intermission → groups and tanks switch golems → repeat until both die.

Next three

  • Mark of Acid / Mark of Blood — Groups swap golems at each intermission so stacks drop; keep middle multi-dotting short.
  • Toxic Droplets — Step on them to defuse — one or two per player, or a mobile immunity — and spread the work.
  • Venom Coagulation — The green group switches to it the moment it appears.

Where the guide disagrees

  • Helical Toxins — groups or partners?The guide’s ability list says groups of 4; its strategy says touch one partner. The page follows the strategy.
  • Empowering Slam — when do tanks trade?One section calls it a hard tank swap; the strategy trades golems at the intermission. The page follows the strategy.

What happens when? · Council

Ula’tek’s Dominance: Not your job — the tanks handle it.

When do tanks swap?

Each tank holds one golem; the tanks trade golems at every intermission.

  • Hold your golem on your side of the room, 40+ yards from the other.
  • On red, move the boss as needed to keep the soak area free of puddles.
  • Trade golems with the other tank at every intermission.
  • Leaving red, walk out before Bloodvenom Injection ends to place its puddle.

Where do I stand?

  1. Two equal groups, one per golem, on the left and right sides of the room.
  2. Red group starts in a corner so Blood Venom pools go along the wall.
  3. Intermission: pair up calmly; mistakes go to one agreed corner.
  4. After every intermission, groups and tanks switch to the other golem.

Setup on Heroic: 2 tanks · 4 healers · 14 DPS. From Method’s guide, 2026-08-12.

What does each role do?

Tanks
  • Hold your golem on your side of the room, 40+ yards from the other.
  • On red, move the boss as needed to keep the soak area free of puddles.
  • Trade golems with the other tank at every intermission.
  • Leaving red, walk out before Bloodvenom Injection ends to place its puddle.
Healers
  • Dispel Blighted Blood only once the player is at the edge.
  • Heal through Contaminate pulses while Venom Coagulation is alive.
  • Mark stacks grow the longer a group stays on one golem and fall off after side swaps.
Damage dealers
  • Split damage so both golems stay at similar health.
  • Green group: kill Venom Coagulation the moment it spawns.
  • Keep multi-dotting from the middle short; it collects both Marks.
  • Use Hero/Lust on pull, since the fight has no burn phase.

On Mythic

  • Mistakes that Heroic forgives now kill: over-soaked green orbs, Toxic Droplet hits, a red soak with too few.
  • Shifting Protovenom marks 8 players — clear it by touching another marked player, never an unmarked one.
  • Intermission orb counts show only briefly: players sort by count — 3s wait, 1s seek them, 2s meet midway.
  • Use movement immunities to take green orbs on the hard sets; kill the green add first every second set.
  • Short on damage? Even out the two health bars by moving players between bosses rather than pausing DPS.

If it goes wrong?

Toxic Droplets
Each droplet left alone hits the whole raid hard when it explodes.
Unstable Miasma
Without a group to share it, the hit is lethal.
Vitriolic Stasis
Any damage lead on one golem is healed back.
Helical Toxins
Both players get Cultivated Burst: lethal damage on expiry plus a large puddle.

Ula’tek’s Dominance — what does the raid do?

Start from:

Every mechanic, in order

for healer
  1. Ula’tek’s DominanceCouncilTankWithin 40 yards of each other, the golems give each other 99% damage reduction.

    Your job: Not your job — the tanks handle it.

  2. Mark of Acid / Mark of BloodCouncilMoveEvery 5 seconds each golem stacks a 40-second DoT on everyone within 40 yards of it.

    Your job: Groups swap golems at each intermission so stacks drop; keep middle multi-dotting short.

  3. Toxic DropletsCouncilSoakThe green golem sprays droplets that each explode as Noxious Blast after 16 seconds.

    Your job: Step on them to defuse — one or two per player, or a mobile immunity — and spread the work.

  4. Venom CoagulationCouncilAddsA large slime that pulses Contaminate raid damage every 3 seconds until it dies.

    Your job: Not your job — melee and ranged handle it.

  5. Living VenomCouncilDodgeHeroic: green lines shoot out from the golem and fly back to it after 4 seconds.

    Your job: Dodge them going out and coming back; never stand between a slime and the boss.

  6. Empowering SlamCouncilTankHeavy Physical slam; each one on the same target adds 15% Physical damage until it hits someone else.

    Your job: Not your job — the tanks handle it.

  7. Blood VenomCouncilDispelHeroic: Blighted Blood’s dispellable DoT leaves a pool when it ends — bigger with more applications.

    Your job: Infected players walk to the edge and get dispelled there, keeping pools off the play area.

  8. Unstable MiasmaCouncilSoakAfter 8 seconds it splits huge Shadow damage among all within 8 yards and stacks Clinging Murk.

    Your job: Red group stacks on the target, then walks to a set spot to drop the puddles that follow.

  9. Bloodvenom InjectionCouncilTankBig Physical hit plus a stacking 40-second Shadow DoT that drops a big puddle when it ends.

    Your job: Not your job — the tanks handle it.

  10. Vitriolic StasisIntermission: Vitriolic StasisAddsAt 100 energy both golems take 99% less damage and the weaker one heals to match the other.

    Your job: Not your job — melee and ranged handle it.

  11. Helical ToxinsIntermission: Vitriolic StasisStackEach player gets a 28-second DoT shown as 4 red and green orbs overhead.

    Your job: Pair with one player whose green orbs bring your total to exactly 4; no rush, golems are immune.

  12. Cultivated BurstIntermission: Vitriolic StasisMoveLands on wrongly paired players: lethal damage when it expires and a big puddle.

    Your job: Send mistakes to a set corner for the puddle; a full immunity or strong defensive survives it.
