Blizzard have unveiled the third class for Diablo III, the Wizard.
At the Diablo III Class Design panel, game director Jay Wilson went into more detail about the game's third playable class, the wizard. A wielder of the elements and a master manipulator of time, the wizard combats the hordes of the Burning Hells by hurling environment-shattering lightning bolts, channeling explosive arcane energies, and creating pockets of space outside the normal flow of time.
Blizzard have also released a move showing some wizardry gameplay, which you can watch here. More information on the Wizard can be found on the Diablo III Wizard page.
