say Heart has to do with uniqueness: then a Witch of Heart could for say manipulate the traits of objects, like a sword swinging at them then all of a sudden it's dull and just leaves them with a bruise, which they could also technically deal with by manipulating the traits of the bruise such as the pain, swelling and mark

I do like the concept, though, as much as I don’t know if it’d actually work, given Properties of Objects tend to fall under the Space Realm.
