Until very recently, a Diablo 3 exploit was allegedly allowing wizards to become permanently invulnerable. A post on the Blizzard forum explained how, with worryingly few clicks, anybody with the Teleport and Archon skills could magic themselves invincible. The instructions were redacted by Blizzard shortly after their posting yesterday, and reports on the forum seem to indicate that the hole's now been plugged. But still, that's quite the exploit.
The original post detailed how to achieve invulnerability in five simple steps:
"Since I can't write a support ticket about this issue I guess i have to make it public.
- Step 1: Select Teleport - Fracture. Bind it to a key
- Step 2: Select Archon, tested with Improved Archon
- Step 3: Hover your mouse over or near your character
- Step 4: Press Teleport
- Step 5: QUICKLY(!) Press Archon
Result: Character becomes Invulerable. No health loss at all, some effects like frozen don't work anymore. Works in Softcore and in Hardcore. Needs a couple of tries to get it working, but once you have the timing it can easily be reproduced. This is pretty much gamebreaking, I hope to see a hotfix soon."
Complaints of ill-gotten legendaries finding their way to the real money auction house have prompted some players to call for an outright ban for anybody using the exploit. Here's a video of the trick in action, complete with commentary by a very angry man.
