Alleria Normal and Heroic raid guide! Crown of the Cosmos, where you fight Alleria Windrunner, is a final boss fight in the Voidspire raid in Midnight. This Crown of the Cosmos guide will walk you through the important healer, tank and DPS raid mechanics you need to clear Alleria in the Voidspire. Special thank you to my guildies in Carbon for raiding with me! This footage is from live servers with my guild. You fight Alleria across three phases, with two intermissions. In each phase, there are large healing absorbs to heal off and projectiles to avoid. In Phase 1, you kill three Sentinel adds. In order for the add become killable, you must hit it with a Silver Arrow. Later, in Phase 2, you must hit the Voidspawn adds (not the Simulacrum) with arrows to make them killable. In Phase 3, you must fight her on a third of the floor until she fills it with void, at which point you pick up a feather by running over it, then jump across the gap to the next section. In the Alleria intermissions, fight the pull that is dragging you to the middle and avoid the silver arrows. If you are being pulled too much, you can stand in one arrow to reset your drag amount. In Phase 2, tank Alleria’s Rift Simulacrum at least 25y away from Alleria, and split cleave onto both targets. Voidlink copies damage done between them, although for some reason this buff is not in the Dungeon Journal it was active on live servers.
