You're welcome!
uuh...sorry if i am a bit slow, but just to be sure of what you're suggesting here:
this is a visualization of both ends of possibile guess results, only that now if you guessed above the result you gain + and if below you gain -? and then you spend + and - in the EM table instead of rolling if you guessed 7+ figures away or use them to cancel each other?
if i got it right...not gonna lie, maybe it's more articulated then what i wanted to do here uhuh. at the same time i like the idea of exhaust magic being just excess magic, not necessarily negative as i put it, and you can spend either negative or positive excess magic for different effects on a different table.
again, this is definetely something that threatens to spiral into a way more complicated system, but....i like the idea of it!
....if i got it right, uhuh. if not, please have patience. if you have other ideas we can also change platform of discussion if you want.
