The Unbinding of Ki’thix – New One-Boss Raid
A new one-boss raid is coming in Patch 12.1.5, serving as a direct continuation of the Venomous Abyss storyline – The Unbinding of Ki’thix! Like the other one-boss raids, the fight against the C’thraxxi general can be done on all difficulties, up to Mythic, with Flex numbers.
New Delve Labyrinth System – Labyrinth of Kindo’jan
Delve enjoyers are receiving a whole new system in Patch 12.1.5 – Delve Labyrinths, or mega delves with multiple chambers, puzzles, bosses, and treasure! The first delve labyrinth arriving with the Patch is the Labyrinth of Kindo’jan, an ancient Amani funeral complex, which includes Kindo’jan himself as a Delve nemesis!
Aqir Invasions World Event
The arrival of Ki’thix as a boss is not the only consequence of our actions in the Venomous Abyss. The Aqir are invading Quel’Thalas in a series of world events in Eversong Woods and Zul’Aman! Drive back the Aqir and work alongside the Aqir Research Enclave for many bug-related rewards.
