Coiled Altar Massively Nerfed — Intermission Health Bonuses Slashed

Datamined and live hotfixes cut Malacrass and Zul’jan intermission max-health buffs by nearly half on every difficulty after Normal Coiled Altar outpaced Normal Ula’tek.

Coiled Altar — the penultimate Venomous Abyss boss — launched wildly out of line. On Normal it was widely called harder than Normal Ula’tek, and Race to World First splits slammed into it early.

Blizzard’s answer: gut the hidden Increase Max Health buffs that slam onto Malacrass and Zul’jan during the Phase 2 → intermission transition.

Health bonus cuts (approx.)

Malacrass

Difficulty Was Now
Normal 133% 38%
Heroic 180% 87%
Mythic 135% 35%

Zul’jan

Difficulty Was Now
Normal 220% 120%
Heroic 246% 155%
Mythic 260% 160%

Because Ghastly Regeneration heals as a percent of max HP, lower ceilings also mean the final phase ends faster.

Official notes also fixed Coiled Altar soft-locks (encounter ending early / failing to enter Phase 3) in the August 19–20 hotfix waves.
