Chaos Bolt
KICKLithiel unleashes a devastating Chaos blast at a random player that deals extreme damage if the cast completes.
This is the mandatory kick of the fight; rotate interrupts so no Chaos Bolt ever finishes.
Lithiel carpets each player's position with Wild Imps via Fingers of Gul'dan, then escapes through a Demonic Gateway, shields herself with Felshield, and pushes an expanding Malefic Wave ring across the whole room; taking her gateway grants immunity to the wave's hit and its lingering 50 percent Fire vulnerability. Keys die to unkicked Chaos Bolts, to demons that survive into the wave and gain 100 percent haste from Malefic Empowerment, and to players who try to outrun the ring instead of using the portal.
Kick list: Chaos Bolt
Lithiel unleashes a devastating Chaos blast at a random player that deals extreme damage if the cast completes.
This is the mandatory kick of the fight; rotate interrupts so no Chaos Bolt ever finishes.
Demonic magic strikes every player's position with a 6 yard splash, and Wild Imps burst from each impact site and start casting Felfire Burst.
Stack close before the cast so all imps spawn in one clump, then use AoE stops and cleave to delete them before the wave.
Lithiel summons a Furious Vilefiend that deals heavy melee damage to whoever holds it.
Tank picks it up immediately and the group kills it before Malefic Wave arrives, because an empowered vilefiend is a key ender.
Lithiel summons a massive Infernal that fixates the tank and hits catastrophically hard if it connects.
The fixated tank kites it continuously and never lets it land a hit; the party avoids its path.
Lithiel opens a gateway between two points; anyone who takes it is teleported across and becomes immune to Malefic Wave's initial hit and its Fire vulnerability.
The entire group clicks the gateway to cross the ring safely; this is the intended answer, not a bonus.
A ring of fel fire expands slowly over the whole room; players it touches take heavy ticking Fire damage plus a stacking 50 percent increased Fire damage taken for 1 minute, and any demon it passes over gains Malefic Empowerment with 100 percent haste.
Kill every demon first, then take the gateway through the ring; anyone clipped needs immediate triage healing.
While conjuring the wave Lithiel wraps herself in a fel barrier that reduces her damage taken by 50 percent for 10 seconds.
Do not dump major cooldowns into the shield; use that window to clean up imps and reposition for the gateway.
Kite the fixating Infernal without ever letting it connect, and scoop the Furious Vilefiend the moment it spawns.
Anyone hit by Malefic Wave carries a nasty DoT plus 50 percent Fire vulnerability, so triage them hard, and use the Felshield lull to refill mana and ramp.
Stack for Fingers of Gul'dan so the imps clump, stop and cleave them down instantly, and hold your kick for Chaos Bolt.
Move to the Demonic Gateway as the wave starts and take the portal; it grants immunity to the wave's hit and vulnerability.
Tyrannical: An uninterrupted Chaos Bolt one-shots most players and a Malefic Wave clip is nearly unhealable through the stacking 50 percent Fire vulnerability, so treat the kick rotation and the gateway as hard mechanics and give the tank a speed tool for the Infernal kite.
