Bom'bay

For those who have completed the quest Zalazane before it was removed in patch 4.0.1, he can provide any of number of random hexes, which most often get you turned into a critter (you can dispel this by right mouse clicking the buff). Sometimes his hexes produce cool effects such as being drunk, ghostly, getting thrown into the air (make sure you have a full health bar for this as the "feather" effect, when you fall back down, can trigger too late on rare occasions and you will fall to your death), or becoming enlarged for 5 minutes (very funny when you add other effects such as Spell nature bloodlust and a "bug" from the gnomish engineering trinket Inv misc enggizmos 06 [Gnomish Poultryizer]).
