This week however I can't remember if I killed oondasta on my dk. There is a macro that lets you know if you have killed certain world bosses that week but it's bugged for oondasta, so it isn't reliable for that boss. Basically if you killed nalak before oondasta on that toon it will say you have killed oondasta also even if you haven't yet, with the macro.
Anyone know any other way I can figure out if I have killed oondasta yet? The toon in question is a dk named blueygooey.
I hope Blizzard fixes this someday.
