The thing about that though, they say, once you've made an incredulously over-powered character making the transition to underdog mortal is next to impossible. I've made so many of both I already know how, when, and where the transition lies.
Though, because I wanted to use a character I've only used one other time, I kind of omitted the choice of the battle being meted in different levels. To be honest I'd actually wanted to use someone else, but again, I had a preference for Avery
