It's a missed opportunity. It would be a lot less luck and add some skill into your staking prowess. I think it would be fun as hell but all these years I've never gotten anyone to do it.

All you have to do is go into death match screen to do an inventory check to make sure each boxer only has runes for Fire-Wave in their inventory and not anything funky like super-weakens or anything to screw with you. And just fuggin go for it, and have fun!
