Diablo III players have discovered an exploit which makes the Wizard class invulnerable to damage and movement impairing effects. Blizzard needs to act fast with a fix to this, in order to prevent any lasting damage being done to the game’s economy.
The exploit disables most effects that prevent movement and also removes the ability to be damaged; at the moment, the glitch only works for the Wizard class. In a game featuring a Real-Money Auction House, exploits like this can cause some serious damage. Players are currently able to blast through Hardcore mode without any fear of death, collecting as many rare items as they like in the process.
You can check out a video of the exploit in action below.
