I put this name, but I could put Mofo's Event xDD, it's not related the name with the event in this case, well, a little bit, but not with the traditional association.
how it works: 10 players, 2 randomly choosen, which won is again protected with barrier and stuff, which lose is romoved from the event, after that, the same again, 2 players randomly choosen...blabla... when the last 2 players are fighting, who won, is the event winner.
