World of Warcraft played host to a bizarre monk bug, resulting in some insane damage numbers.
Reddit user MidOrFeed put the above video of this bug up on reddit, and various tweets and forum posts appeared as more and more players discovered the bug, most likely by accident. This could have been seen as an exploit by Blizzard if players were to deliberately take advantage, but less likely if players just happened upon it by accident and proceeded as normal, rather like we see in the video above. An example of exploiting might have been for players to assemble a raid principally comprised of windwalker monks, for example.
The monk bug was based on the interaction of two abilities, Rushing Jade Wind and Spinning Crane Kick. Rushing Jade Wind is an ability affecting Spinning Crane Kick, giving it a damage multiplier. It seems like there was the accidental addition of some additional numbers to the Spinning Crane Kick multiplier, making the kick far more powerful than was ever intended. A cursory glance at some World of Logs pages reveals that, with these high numbers for monk output, Spinning Crane Kick was dealing about 98% of the damage the monks were putting out. And that was huge damage. World of Logs has one monk at 4.48 million DPS.
Now, clearly, this is not working as intended. While monks needed a DPS buff or two, they definitely should not have been putting out these sorts of numbers. People who have played for a couple of patches, specifically the Dragon Soul 4.3 Cataclysm patch’s early days, will remember a similar issue with retribution paladins, where their Censure ability that was dealing far too much damage.
Rather like the Censure bug, this was hotfixed at high speed, with rolling restarts to repair the bug completed at around 5.30pm PDT, as Blizzard confirmed on Twitter.
