ok, one of the thing about the new Wizard schools, etc it that a wizard never runs out of spells. While I like that to a point, I also like the stories where a wizard runs out of magic and has to use his wits. I don't want to limit school power and cantrip, but tell me what you think about this. If you are out of prepared spells, you can still use your at will powers and cantrips, but there is a cost. You need to make a spellcraft check. If you fail you take some subdual damage due to exhaustion. Just to emulate the "Drained wizard" fluff. What do you all think?
