Kokia is an add-and-ground-denial fight: every 100 energy she casts Ritual of Blazebinding to summon a Blazebound Firestorm that must be swapped to, kicked, and killed away from the group, while Molten Boulders and Scorched Earth steadily eat the usable floor. Keys die to a Blaze Volley that gets through, to Burnout explosions on top of melee, and to tanks flattened by Searing Blows once the Searing Wounds stacks ramp.
Kick list: Blaze Volley
At 100 energy Kokia summons a Blazebound Firestorm at a targeted player's location, searing everyone within 12 yards of the spawn for heavy Fire damage.
The targeted player places the add close to the boss but out of the melee camp, and the whole group swaps to it immediately.
The Blazebound Firestorm blasts the entire party with flames for heavy Fire damage. It is interruptible and is one of the two most important kicks in the dungeon.
Assign a kicker to the add the moment it spawns; this cast must never complete on a high key.
The Blazebound Firestorm hits every player with unavoidable Fire damage plus a stacking damage-over-time effect that runs for 8 seconds.
Healers cover the burst with a cooldown if needed, and the group kills the add before repeat casts stack the dot.
When the Blazebound Firestorm dies it explodes, dealing very heavy Fire damage to players within 20 yards, and in Mythic+ it leaves Scorched Earth that ticks Fire damage on anyone standing in the flames.
Step out of the add's 20 yard radius just before it dies and never stand in the Scorched Earth it leaves behind.
Kokia slams a boulder down in front of her, hitting players within 6 yards, then it rolls forward up to 40 yards, knocking back and burning anyone it touches before exploding. In Mythic+ its path also scorches the ground.
Sidestep the frontal immediately and keep the boss faced away from the group; the tank kites her slowly around the room so clear lanes always exist.
Kokia strikes her target 4 times over 3 seconds at 150 percent weapon damage per hit, and every strike applies a stacking Searing Wounds burn that ticks every half second for 8 seconds.
The tank uses active mitigation or a defensive for every cast and the healer respects the stacked burn that follows.
Kite Kokia slowly around the edge of the room to preserve clean ground, bring her next to each Firestorm for cleave, and hold a defensive for every Searing Blows.
Budget for the unavoidable Inferno hits and the stacking Searing Wounds ramp on the tank, and keep a cooldown ready in case a Blaze Volley slips through.
Swap to the Blazebound Firestorm instantly, own the Blaze Volley kick, and step out of the Burnout radius before the add dies.
Sidestep every Molten Boulder and stay off Scorched Earth; the usable floor shrinks fast on higher keys.
Tyrannical: An uninterrupted Blaze Volley or a Burnout taken in melee moves into one-shot territory and the Searing Wounds ramp gets brutal, so rotate tank externals through Searing Blows and treat every add kick as mandatory.
