I think the roles of Witch and Maid don't have much difference in their powers. I think their difference lies in their role in their session.

It depends- Maids Improve and Make Better, as well as Make. They can also be seen as ‘keepers’ of their Aspect, and to be ‘Made’ of their Aspect. A Witch may manipulate their Aspect, but they’re not ‘made’ of it, whatever that entails. They may Change what is already there, but not Make something new, perhaps. But there is an overlap with both the Make class AND the Destroy Class, since Changing allows them to reach the Improve and Reduce sort of sides of them.
