Re: expendable foci vs. charges
I thought of that, but that's why I gave the example of 2x12. I doubt he'd allow me that many, and even so, I might have 8 spells, so hundreds of foci, and the component might be a valuable item. More likely, I'd have about 6 uses for each. In charges, that would be -3/4, and they would automatically recover, and I wouldn't have to spend END. (Yeesh - the more I think about it, the crazier it seems.)
