Ruby Life Pools

Thunderhead and Flamegullet

• Fixed an issue where the progress bar could reach 100% when the Avatar reached 99% health.

The Venomous Abyss

• Resolved an issue where players could fall through the world in The Serpent Warren.

Vashnik the Malignant

• Fixed an issue causing Stygian Burst to inflict damage in a larger area than intended.
• Shrouded Venom health redistributed and now have 40% health and 60% shields.
• Fixed an issue causing players to get hit multiple times from the same wave in a short period of time.
• Fixed a rare issue where players using Harpoon on a Venom while inside the Malignant Cavity would cause them to fall through the playspace.

The Coiled Altar

• Fixed an issue where the encounter would rarely fail to properly transition to Phase 3 at the end of the intermission.

Ula’tek

• Blight Vein damage reduced on Heroic difficulty.
• Grasping Fangs now targets three players per side on Heroic difficulty, no matter the instance group size.

• Resolved an issue causing the damage of Spectral Coils to unintentionally scale on non-Mythic difficulties.
• Spectral Coils now requires 40% of the raid to reduce its damage to a minimum value.
• Spectral Coils adjusted on Heroic difficulty so it has more consistent timing.
• Corrected an issue where the Blight Vein debuff did not properly inflict its damage based on the number of stacks applied, on Heroic and Mythic difficulties.
• Corrected an issue where Hunters’ Stampede pets from the Pack Leader hero talents would not properly damage the Heart of Ula'tek during the encounter.
