Re: Harry Potter HERO
That's coherent enough to work!
However, really basic spells, (like lumos) seem to almost always work. I would probably allow my players to buy off the magic skill roll (for free) for a set number of spells everytime they moved up a year. I.E. at the beginning of first year, all magic requires a skill roll. Once they graduate from 1st year, they get to start using one or two spells for free, and so on. The "Magic" skill should also let them do some tricks "for free" such as send non-harmful sparks out of thier wands. Harry does this when he first holds his wand and in the Triwizard tournament and the exploration of the Forbidden Forest in first year, students use sparks without any sort of incantation or even effort really. Also, if a young (and especially magical) student gets really mad, they should get a few tricks done without wands, and without set powers. Example, when Harry blows up Aunt Marge in the third book, and also when the (locked) cubboard flies open as he walks past. Harry at that point is slinging magic around in a rage, not even needing the benefit of a wand.
