Twilight Lord Kelris Overview: Abilities, Phases, & Preparation

Twilight Lord Kelris has two phases and four abilities that he will rotate through. Every ten seconds, he will cast Shadowy Chains, with Mind Blasts in between. Shadow Crash and Sleep are cast at regular intervals as well.

In Phase One, which lasts until roughly 35% of his HP remains, two of Kelris' abilities are interruptable: Mind Blast, and Shadowy Chains. These two abilities should be interrupted as often as possible by melee DPS and Tanks – especially Shadowy Chains.

In Phase Two,none of Kelris' abilities are interruptible, and he will seemingly randomly target melee DPS with Mind Blasts. But anyone can be targeted with these uninterruptible Mind Blasts, so it’s essential for all players to bring along Shadow Protection Potions for Phase Two.
