I was thinking about the elements. Ignoring aesthetics for now. The main real difference is the piercing/knockback effect. For example, an ice spike would dig in, and an air blast or swirling blob of fire would knock the target back somewhat more and dig in less. And a chunk of rock would be in the middle. Would adding an additional 300 OM to the cost of the original move be sufficient to cover a variable element, if I give a list of the elements and any potential variations between them? Assuming all variation was able to sit on the low knockback + high piercing to higher knockback + low piercing scale. Or would the potential utility purposes of being able to wield multi elements be considered too diverse?

Either way, I'd like to try and negotiate a way to actually be able to use a bunch of elements and not just fake it if possible.
