During the show, Blizzard Entertainment also unveiled the game’s third playable class: the wizard. A wielder of the elements and a master manipulator of time, the wizard can hurl environment-shattering lightning bolts, channel explosive arcane energies, and create pockets of space outside the normal temporal flow. BlizzCon attendees were able to adventure as either the wizard or the previously unveiled barbarian or witch doctor, battling alone or with up to three other players through the catacombs beneath Tristram Cathedral to a final showdown with the Skeleton King
