No one can stop death. The Prime Evil rages within the Black Soulstone, its essence crying out for vengeance and liberation. Before the artifact can be sealed away forever, Malthael - the Angel of Death - appears in the world of mortals with a new deadly goal: he intends to steal the Black Soulstone and bend its hellish power to his will. Thus begins the end of all things.

In Reaper of Souls, the five original heroes from Diablo III - Barbarian, Demon Hunter, Monk, Witch Doctor, and Wizard - are joined by a new champion: the Crusader. Clad from head to toe in scarred armor, the Crusader is an unstoppable force of righteous destruction, channeling the power of divine wrath to avenge his demonic prey.

Players embark on a dark and perilous journey through a challenging new act, traversing terrifying landscapes, visiting the legendary city of Westmarch, and slaying countless minions all intent on bringing a cruel end to their quest. The adventure culminates in a confrontation with Malthael, the fallen Archangel of Wisdom, an otherworldly being of unfathomable power whose twisted plans spell doom for the innocent people of Sanctuary.
