XP had the option to set how much of an opponent's physical or magical defense factored into an ability's effectiveness, essentially letting you create attacks that could ignore armor or magic defense. As far as I can tell, this doesn't appear to be directly possible in VX Ace, at least not with weapons. I can use the damage formula for skills to have them ignore DEF or MDF more, but this can't be done for weapons. Is there any way to get this working for weapons, or should I just make a new basic attack skill for alternative types of weapons?
