Raszageth the Storm-Eater

Official Overview (Blizzard)

Raszageth and her Primalist forces seek to shatter the prisons that hold her siblings. As the battle begins, Raszageth uses Hurricane Wing to sweep her assailants from the central platform. Upon reaching 65% health, Raszageth begins an aerial assault against Fyrakk's and Vyranoth's prisons with Lightning Devastation while summoning ground forces to attack the prisons directly. Surging Ruiners Surge with lightning, draining the vault of its power. When the integrity of the vault falls to 50%, Raszageth lands on Iridikron's prison and begins to drain the vault's power using Stormsurge. When the integrity of the vault falls to 0%, Raszageth takes off and summons Colossal Stormfiends to drain the vault of its remaining power. As the vault fails, Raszageth returns to the central platform and becomes the heart of a Raging Storm. The Storm-Eater brings the full force of her abilities against her assailants as she ushers in the dark clouds of a new age.
