While I really, really like this idea, I think a class like this would be better suited as a Disciple of the Hand class. Why? Two words: player housing.

Let Dancers be the support class. Painters could make their own paints, wallpapers, artwork such as paintings and murals, wall colors, books and other printables, and more.

That's my preference. However, it must be said Relm is amazing, so I wouldn't mind either implementation.
