Getting into my own HC about Fresh, he's a bit of a detritivore when he can't access hosts. Magic is his main diet, but he can't really process it unless its a lot more chopped up and, well, processed by someone else. Usually he'll get that by eating Souls, but when he can't I think he makes due with things like dust and other magic waste.

I don't think its preferred, takes a lot more to digest than just a Soul, and has way less magic as well. Its not too bad though, a lot of the magic he gets from a soul he uses to control and maintain the body he's in, so even if he's not getting nearly as much magic on dust alone, its not like, fatal.
