--Change the item useable amount to infinity if you want it to be used that way

--This only affects out-of-battle appearences. If you want to change the hero completely (in battle animations, moves, etc.) I'll make pictures of that as well.
-- I just realized I could've made those last two images smaller. Heck with it, I'm too lazy to fix that.
