Move Creation Workshop

[Mark]

Guu has a move where she does exactly what you're describing, and with just a basic move. And in this instance, Jade's mention of Malleability is how she does it, though I don't see it being a huge difference to regrow the limb and keep the damage vs move the injury to somewhere else and keep the damage. Based on that I don't see a reason you couldn't accomplish the same thing with just a Move (with a large stamina drain, probably) and Regeneration. For something like this though I'd definitely bang on Greg's door when the approval is needed, but that's my two cents.
