Patch 12.1 Hotfixes — September 3, 2026

Oversurge — Corrected an issue where Oversurge did not properly increase the healing done by Surging Totem or Overflowing Shores.

Spark in the Night — Fixed an issue where the achievement was not granting credit for the Sparks of War quest if completed in the Coiled Isle, Val, or Naigtal.

Radiant Drake entrance-return NPC — Fixed an issue where the NPC did not appear in Mythic+ Ruby Life Pools after defeating the final boss.

Caustic Waves — Adjusted Caustic Waves so they cannot be avoided by swimming under them during Ula’tek in The Venomous Abyss.

Blight Vein — Corrected an error in the Blight Vein spell description that pointed to the wrong damage value during Ula’tek in The Venomous Abyss.

Perfected Guillotine — The Zul’jin’s Guillotine Technique trinket effect will no longer target enemies who are not engaged in combat for its second target.

The Darkwell — The Darkwell should now remain for characters who have not finished the War of Light and Shadow Campaign but have completed the Arator quests for the Curse of Ula’tek Campaign.
