FP Cost Change for spells

[Blind Mapmaker]

Makes sense to me. I know a system where powerful spells also cost regular FP in addition to magic energy. It does make for a little more book-keeping, but it does add a nice distinction between complete bookworms and mages leaning more mens sana in corpore sano. The latter might be doing things like martial arts or dancing just to keep up their stamina.

I don't get "the purpose is to allow mages to use magic in longer fights or other more extended crisis situations." Do you mean mages don't incur the FP "tax" if they take a long time to build their spell maybe with ceremonial magic? I think that would be a bit counter-productive, because ceremonial magic seems more physically taxing, but it could work either way. Just taking extra time with no other benefit would also work. I'd suggest going the other way though and make low-cost spells use only magic FP. That way you could lob 1d Fireballs all day, but if you need more oomph, you'll have to shell out physical FP.
