Abilities & Strategy

Overview

Alleria Windrunner begins the fight held back by Undying Sentinels from the Void. She periodically strikes out at friend and foe alike with both Void effects and Silverstrike Arrow. When each of the Undying Sentinels have been destroyed, Alleria crashes into the platform and creates a Rift Simulacrum to assault her enemies with Call of the Void and Ranger Captain's Mark. When the Rift Simulacrum is shattered, Alleria releases her full Void abilities upon all players.
