Ula'tek

FIGHT OVERVIEW

OVERVIEW

Three phase encounter with a brief intermission.

Prepare two groups. You'll have to split to different sides in phase 2.

Ula'tek's eggs are a core mechanic. Eggs hatch into good adds or bad adds. Bad adds happen when eggs are hit by venom mechanics, or hatch naturally after not being killed. Good adds happen when eggs are smashed and broken early.

Pick up eggs to keep them safe from venom mechanics, such as Caustic Waves.

Tanks should stay in melee range of Ula'tek and her Tail otherwise the raid takes damage.

Soak the smashes from the Tail.

Take advantage of the damage amp and attack Ula'tek's Heart during Rage of the Shackled.

In the phase 2, destroy the Warden, then destroy the eggs on the ledges.

During phase 3, help soak three debuffs by loosely assigning players to three groups: melee, ranged, and healers.

FIGHT CHANGES

The fight is not much different on Heroic.

Egg adds gain a few small new abilities.

Breaking Grasping Fangs in phase 2 applies a raid-wide DoT instead of just to the tethered player.

Phase 1

Stage One: Fury of the Serpent Mother

Ahead of time, prepare two groups.

The encounter has a two-part soak, and the raid will split into two and cross to different sides in phase 2.

The same two groups can be used for both mechanics.

Phase 2

Stage Two: Children of the Doomscale

Ula'tek dives away and players should go with their groups to opposite sides of the room.

Travel across the Venom and climb the stairs. The next part of the encounter takes place on these ledges.

Intermission

Intermission: The Shattering

Phase 3

Stage Three: Ula'tek's Ascension

Phase 3 has mechanics from phase 1 as well as a new one: Serpent's Bite.

It's a new soak mechanic and requires three different soak groups.

Plan the groups ahead of time: melee, ranged, and healers.

Pick an ability to see its details.

Malignant Shell

Eggs

Eggs appear throughout the fight. Players can pick them up by walking over them. Eggs hatch into two types:

1. Blightscale Viper, which is dangerous and fully grown. Hatches when an egg's cast finishes or is hit by a venom mechanic.

2. Blightscale Rawling, which is weak and hatches early. Damage the eggs and kill them or smash them with Ula'tek's Tail smash mechanic.

Always avoid hatching vipers. They deal a lot of damage and will probably wipe the raid. Pick up the eggs and keep them safe from any venom. Kill adds when they appear.

Both add types gain abilities on heroic.

Rawlings apply a stacking DoT to their target, and vipers create ground AoE, shield themselves, and deal raid-wide damage.
