Ula'tek
The Venomous Abyss · boss 8 of 8
The great shame of the Amani empire. The vast complex of Altal'Utek was created to imprison the weapon that proved to be as much of a threat as the enemy she was intended to destroy. Ula'tek has risen from her ancient slumber and threatens all of Azeroth if she should escape.
The mother snake floods the floor with venom. Her eggs hatch when venom touches them, and every hatch poisons the raid. Keep eggs away from waves.
An egg-management fight. Damage on the boss is almost incidental — you win by controlling where the eggs are when the waves arrive.
What actually kills you
Everything else is noise until these three are handled.
- Eggs touching Caustic Waves. Every Blightscale Viper that hatches puts Putrid Membrane on the whole raid.
- Spectral Coils landing on too few people. The damage is split by how many stand in it — go together.
- Letting a Blightscale Clutch grow. It gets stronger until destroyed.
Your job
If you tank
- Ula'tek uses Unchecked Rage when nobody is in melee. Stay in range.
- Mother's Wrath knocks you back and marks you, and her Gore Rattle behaves the same way if she has no melee target.
- Stone Venom and Hobbled stack on you. Swap before you are rooted in a bad spot.
If you heal
- Every viper that hatches is another Putrid Membrane on everybody. Fewer hatches is less healing, permanently.
- Necrotic Vapors stack all fight and never fall off. Like Vashnik, the back half is far harder than the front.
- Spectral Coils is soakable — if people spread out for it you cannot heal through it.
If you DPS
- Move eggs away from the wave paths. That is your real job.
- Kill Blightscale Clutches early — they grow.
- Doomscale Wardens buff nearby eggs with Writhing Gestation. Kill the warden, not the eggs it is buffing.
How the fight goes
| Part | What to do |
|---|---|
| Stage One: Fury of the Serpent Mother | Waves and eggs. Keep them apart. Intercept Toxic Incubation if your raid calls for it. |
| Stage Two: Children of the Doomscale | Wardens empower the eggs and Doomscale Eggs start hatching. Kill wardens. |
| Intermission: The Shattering | She breaks the arena. Space gets smaller. |
| Stage Three: Ula'tek's Ascension | Call of the Serpent keeps summoning while Circling Prey destroys what safe ground is left. This is a race. |
Heroic vs Mythic
What changes on Heroic
- Blightscale Rawlings cast Poisonous Bite on players — the half-hatched adds are no longer harmless.
What changes on Mythic
- Blightscale Spawn become Hardened: their shell absorbs the next hit and they cannot be moved while it holds. Break the shell before you try to reposition an egg.
- Rawlings gain Boiling Venom, which lets them use Acidic Expulsion.

Worth a bonus roll?
That depends on how many items on this table you still want. A boss owing two or more is worth returning to; one owing a single piece is a vault pick, not a roll — the bonus roll guide explains why, and the planner works it out per spec.
