In the table top game I run {Saga: the Game, available through lulu.com} we are developing new content and play testing some ideas.
One of the ideas we came up with is an anthropomorphic armadillo shaman with some magic enhancements. We call him the "Sharmadillo". His natural armor is enchanted to outright ignore damage that does not exceed a certain level of damage and the damage he does take is reduced by the amount his power ignores. As he can not don the armor of men and elves he is somewhat hamstringed so we wanted to make him tough enough to hang with the big dogs. {We are playing end game content and the heroes must of course be very powerful.}
So what are some of the oddball characters you have allowed in play over the years?
