World of Warcraft’s Raid Tuning Cuts Ula’tek’s Health and Damage
Blizzard has applied the Ula'tek and Vashnik changes, while adjustments for Entombed Sentinels, Twin Fangs, and The Coiled Altar remain pending.

Ula’tek’s raid tuning is now partly live. The November 6 hotfixes apply a 15% health reduction on Heroic and cuts to several attacks across difficulties. They also revise two announced damage figures: Caustic Waves impact damage is down 32% on Heroic and Mythic, and Falling Debris damage is down 77% on Mythic.
Blizzard’s raid-tuning notice covered five encounters. The November 6 hotfix notes confirm that Ula’tek and Vashnik’s changes are live, while adjustments to Entombed Sentinels, Twin Fangs, and The Coiled Altar remain pending. Blizzard said its hotfixes page would be updated as changes went live.
The Ula’tek changes also adjust health scaling for five enemies on Raid Finder, Normal, and Heroic, accounting for smaller groups while reducing base health so larger groups do not push it back up. An earlier Ula’tek tuning pass targeted stages 2 and 3. The current set reaches other parts of the fight too, including egg counts, the number of targets selected by several abilities, and Caustic Waves during Phase 3.
