Blizzard is on the case following an exploit found in Diablo 3 that makes Wizards invincible.

Blizzard is in the process of rolling out a hotfix that will put an end to an exploit which made Diablo 3's Wizard class invulnerable, according to a post on the official battle.net forums.

"We are currently rolling out a hotfix for a recent bug regarding invulnerable Wizards," reads the post.
