* Harry has been using sponsored magic in the form of hellfire and soulfire for several books now. One of the benefits of sponsorship is that the sponsor can pay the costs for you. That gives him the ability to do extra stuff without taxing himself, at the cost of sponsor debt. After the line I quoted above, note that he brings Hellfire to the party pretty much *every* time he does anything magical for the rest of the fight. This is one reason why it's difficult to be a "pure" wizard and play in higher leagues of supernatural power.
Question on this. The book says the sponsor can 'pay the costs' for a spell, then goes on to list one thing: once per roll, the sponsor can give you a free tag on an aspect without paying a fate point, this gives you debt. Are you saying that one could also have the sponsor instead of doing this, eat a point or two of stress for the spell for debt as well?
If so, this makes sense. I just don't see it in the book other than the vague 'pay the costs'.
I wanna be sure I got this right, I'm going to be doing a game with wizards and one of my players wants to eventually be Mab's bitch. Er. Swear a pact with Mab.
