I love this poaching for consumable abilities idea. It opens up so many possibilities. Like you could recreate Relm's FF6 Sketch ability with this. And like Skip Sandwich said, this creates a new angle for a summoner, as well. "Monster essences," indeed. Really any sort of class that might use enemies' remains in battle: some kind of soul collector, necromancer, voodoo witch doctor, animist, medium, whatever.
I approve so hard.
