"Well," Bolin explains with a little bit of patience, "the whole point is so that we don't kill each other in the ring. It would... kind of get a little messy since this is just a sport. I mean, I've put my life on the line... waaaaaay too many times by now to really be comfortable with making a living out of it."

But he walks into the ring and earthbends one of the clay discs up. "I mean, these things pack a punch even if I were to hit you with it, but it's nowhere near the level of damage I could do if I could just earthbend or even lavabend at my opponents! I could kill them! The whole point is to, given limitations, see how good and creative you are given limitations. It's now about finesse, execution, and strength."
