Player receives Developer item in the mail, one-shots Ulduar on the WoW Insider offers a little detective work suggesting that the surprising success one World of Warcraft guild was having knocking off Ulduar's toughest achievements is the result of one of the guild's members coming into possession of a developer item called "Martin Fury" that's not intended for player ownership, which allowed one hit kills on the game's roughest monsters. They speculate how this may have come about, but the incident seems to be over: "The whole thing is essentially wrapped up now, the accounts are banned, the item is gone, but it's certainly a memorable event." Thanks John.
