they could be the most powerful at magic but physically weak to keep things balanced. i'm not sure about physical changes, possibly a more aged and haglike appearance, with some kind of "devil's mark" somewhere on their body
possible unique powers could include the ability to brew potions and create amulets, invoking magic with their blood, flight (with a broom), and using familiars as their remote eyes and ears
possible weaknesses could include salt (because it weakens magic), water (because people were drowned in witch trials and also a wizard of oz reference), and sharing the pain of any harm done to their familiars
