BTW, a note on ritual. Hope can do a ritual to gain an AP off one of her other spell arrays. It would be DC16, so she makes it on a 1, and it takes one round to do if she spends a hero point. Compared to using that hero point to power stunt the spell, it has the advantage of lasting the entire encounter instead of until she stops using it, and the disadvantage of requiring a round to do the ritual (rather than instantly), and the need to make a check, which is in this case moot since she always makes it.
So by Ap, that would be Alternate power right? What sort of Alternate Power would be good for this? I'm just learning and I haven't yet gotten my Ultimate Powers book yet.
