Allright, first off i'm a newbie, but throughout the years i've got to know alot of bugs/exploits mostly by luck or curiousity. So i found this site which i had visited a long time ago and had made a login on, and became active on it now after 4.0.3a.
Anyway, i was online yesterday on my shaman, just fooling around on my old realm with some irl m8's, when i logged off, my friend i was boosting died. he was like "wtf just happened" on skype.. he after checked combat log and it said that my Fire Nova totem had killed him. Needless to say we tried it again and again, didn't work all the time, need to time it a bit apparently, altho not given too much theoretical attention to it yet. Anyway, it kills unflagged / random lowlvls in org too, killed some bank chars yesterday :> Anyway, hope you can confim this and have fun with it.
This was done on EU servers, just FYI.
