Hotfixes August 20: Heroic Ula'tek Nerfed, Affliction Bugs Fixed

Blizzard tunes Heroic Ula’tek, hardens Vashnik’s Shrouded Venoms, fixes Affliction set interactions, and softens Nightmare Prey’s Toxic Snare.

Another Season 2 day, another hotfix dump. August 20 focuses on Venomous Abyss pain points, a pile of class bugs, and a Prey affix trim.

Heroic Ula’tek

  • Blight Vein damage reduced on Heroic
  • Grasping Fangs now hits three players per side on Heroic regardless of raid size
  • Volatile Purge AoE scales with raid size on Normal/Heroic (largest in 10s, smallest in 30s)
  • Spectral Coils no longer unintentionally scale on non-Mythic; needs 40% of the raid to minimize damage; Heroic timing cleaned up
  • Blight Vein stacks now deal damage correctly on Heroic and Mythic
  • Pack Leader Hunter Stampede pets correctly hit the Heart of Ula’tek

Elsewhere in the raid

  • Serpent Warren fall-through-world fix
  • Vashnik — Stygian Burst radius fixed; Shrouded Venom now has significant health and shields; multi-hit wave bug fixed; Harpoon-in-cavity fallthrough fixed
  • Coiled Altar — rare failure to enter Phase 3 after intermission fixed

Classes and systems

  • Havoc Aldrachi Reaver — Evasive Action grants the extra Vengeful Retreat again
  • Resto Druid — Tranquility tooltip and Overgrowth + Soul of the Forest targeting fixed
  • Marksmanship — Precise Shots double-dip with Unload closed; Explosive Shot AoE respects damage reductions
  • Holy Priest — Benediction + queued Holy Word no longer eats the proc
  • Elemental — Master of the Elements buffs Earthquake again
  • Affliction / Hellcaller — multiple Wither / Malefic Grasp / Darkglare / 4pc Unstable Affliction → Wither stack fixes

Also: Azta’rec delve kill no longer spoofs a Zek’vir flee with no loot; Ruby Life Pools and Sethraliss Avatar progress-bar bugs fixed; Toxic Snare (Prey) damage and slow reduced; Companion Command Crystal is BoP; campaign quest completes if you were dead on the last boss.
