[@Scio] As the characters develop more abilities or sub-abilities (Like, I could probably split Rhian's into two-- one for bug control and one for bug size scaling), I think a ranking system could possibly be good. A-F. Kinda fits the school theme, too, I guess. If we really ever came to a hair splitting moment, however, I would rather do the whole "Pick a number between 1 and 10" deal.

I'm a little less enthusiastic about the abilities being cut up into spells. Makes it seem a little less like X men and more like Harry Potter. (As much as I love HP, I just like the X Men feel for roleplaying better. Gives you a bit more flexibility.)
