is it only for physical transformations (eg like beast becoming human again in beauty and the beast) or like evil character turns good transformation?

becuase I lean more towards a non physical transformation type, but I’m not sure if that’s what this jam is about. So I thought I’d ask.

Mental transformation is absolutely necessary and welcome! 

Ideally transformations will have both mental and physical aspects, encouraged in the To Change system, but there is definitely room for transformations that lean more heavily in one direction, if that's your thing.
