I've been looking around a while and I'm not sure if this is built into MV or exists somewhere. But I'd like to dictate custom MP costs for my spells. Specifically I want a spell to become more costly as a characters M.Atk grows. My max level is 1000 and at that level most characters have like 10kmpish .. So a spell they learn at level 20ish that costs like 50mp is now nothing and mp is trivialized. So I want to make it so as the spell gets more powerful it also costs more.
