My latest Fun Idea is a kung-fu wizard. It's the wizard part that's important here...
What I want to do is give this guy some dice in Words of Power (functionally, Cosmic Power with If/Then (must vocalise and gesture) and Obvious) for his magic, and have a staff whose sole purpose is to make his magic more powerful.
So is it acceptable to have a Flaw that only applies to some of the dice in a power? The only other way to do it is to take Augments and then limit it to being used only for Augment... but that still comes out more expensive than just buying more dice in the original power.
To illustrate the sort of thing I mean: I want to do something like give him 4d in Words of Power, then add another 4d that rely on the Focus (which would have Accessible, as a staff's big enough to steal...).
