Changing things like their names and stats, creating new materias and equipments from existing ones? I want to do something like creating an Ice materia that never gives Ice 2 or altering the -/+X% bonuses they give.
Also, is there a way to lock certain materia into an equipment?
I was thinking, it'd do for a great class mod if you could lock materia to equipment. So characters would have their class skills on weapons and a subclass on the accessory.
