Diablo III picks up the story twenty years after the events of Diablo II. Mephisto, Diablo, and Baal have been defeated, but the Worldstone, which once shielded the inhabitants of Sanctuary, has been destroyed, and evil once again stirs in Tristram.

Overview

Playing as a hero from one of five distinct character classes, players will acquire powerful items, spells, and abilities as they explore new and familiar areas of Sanctuary and battle hordes of demons to safeguard the world from the horrors that have arisen.

Classes

Barbarian: Barbarians are savage wanderers who never flinch from close-quarters combat. Mighty ground stomps, leaping attacks and dual-wielded slashes leave a barbarian’s enemies dead in their boots and send any survivors fleeing for cover.

Demon Hunter Demon hunters are relentless vigilantes who execute their infernal targets with an arsenal of ranged weapons. They crouch and take aim far from danger, relying on bows, deadly traps, and projectiles to swiftly bring an end to the creatures that haunt their world.

MonkMonks are sacred warriors who channel divine power through sheer force of will. Healing waves, mantras of protection and attacks empowered with holy might are all within their purview.

Witch DoctorWitch doctors are spiritual warriors who summon dead souls and crawling creatures to do their bidding. By surrounding themselves with conjured zombies and vermin, witch doctors are free to assault their enemies with exploding skulls, acrid poison clouds, and wasting curses.

WizardWizards are renegade spellcasters who use their bodies as vessels for arcane energy, forsaking the more careful path favored by other magic users. They manipulate all manner of forces to disintegrate, burn, and freeze their foes, and they can control time and light to teleport, create powerful illusions, and deflect oncoming attacks.
