I've been giving it some thought and I suddenly realize that all this arena stuff is just too difficult for me. I surrender. See ya round.
I'm happy to give you a day or two to re-consider if you want, otherwise I'll engineer the situation so that my character flees the scene after inflicting a minor wound, I'd rather not murder your character.
Also, don't end the fight with a ceasing universe, it pisses off anyone who happened to be reading the battle ^_^
