Wait if the shaman was just after the prize money, why didn't he just wait for the tournament to end, take over the body of the winner and just like ditch the money somewhere secret so that he could pick the money up from in his real body later?
For some reason, every time a new chapter of this comes out I can't for the life of me remember anything about the story. I remember having to reread the series when the last chapter came out and I'm gonna have to do that again.
