Move Creation Workshop

[Thor]

Not sure if this is more a post for quick questions or not but, I was thinking of a character with debuff and Physical strength whose attacks debuff opponents buy causing crippling wounds (broken bones, profuse bleeding, cut tendons and the like). Is that doable? And maybe more importantly is that a good idea, or would I just be wasting a thousand OM on something our damage system is supposed to already account for?
