Perfect doomsday: In WOW, there are many copies, and the Hammer of Doomsday is about 50-60 copies. Perfect doomsday means that in the copy of Doomsday Hammer, you don't kill any guard boss. You sneak directly to the Hammer King of Doomsday (so only druids and stalkers in the squad can complete the perfect doomsday). After killing the king, the king's attendants will surrender and admit that you are a new bad luck. And bring a tribute. The quality of the tribute is a little better than the blue dress of the same level. Then, you can enjoy the treatment of the king. The guards who deliberately avoided killing before will greet you and give you a few BUFF for 2 hours. This is definitely bad luck.
