The Diablo 3 God Mode bug allows players to turn invincible, making Inferno - the hardest difficulty - or farming for rare items considerably easier. In a lengthy thread on the Diablo 3 official forums, Blizzard representatives have posted saying a hotfix is now being released.

Blizzard employee Xordiah posted in the thread, revealing that a hotfix is being released for the "recent bug." While YouTube videos surfaced July 22 demonstrating the bug, it had been active for around a month. The question is why Blizzard didn't issue the hotfix before it went mainstream.

The bug is simple to activate: hover the mouse cursor over the character (it has to be a Wizard), use the Teleport Skill, and then hit Archon simultaneously. Players will be floating mid-air and will become invincible while being able to deal damage. Even when the animation expires, players are still invincible.

It's a major bug in Diablo 3, and for Blizzard, because it makes the aforementioned difficulty level void. It also means that the Real Money Auction House could be exploited: high-end, rare, items could be farmed for easily. In theory, rare items should be harder to get and, therefore, the value on the Real Money Auction House is high. Obviously, being able to farm for items while invincible removes the risk.

Also, a player who posted on a thread discussing the issue said he defeated Diablo - the final boss - three times using the bug.

It's not the first issue for Blizzard and Diablo 3: players have been charged unexpected amounts of money, despite the item being listed as free, through the Real Money Auction House. The International Trade Commission forced the company to offer refunds, even though Blizzard implemented a level cap for eligible players.

The company has also come under criticism for not creating meaningful end-game content. The issue with the end-game content is that even after completing the stags, the game doesn't unlock additional content; however, the option to work through the three subsequent difficulties, assuming players start at the lowest, or farm for items exists.

When players vs. player (PvP) combat goes live, then it'll be an option for players. However, it may not be the long-term fix Blizzard needs.
