[@TheUnknowable], so I'm trying to think about how to best employ something like witchcraft in situations where Sam may need something instantly. Considering she has no combat/fighting experience, her skills will really revolve around deception/misdirection. 

I'm thinking like an "illusionist" type thing for her, which goes along with her shifting ability. Her power would essentially be planting suggestive thoughts, or conjuring something that might be perceived as real, or something like causing temporary blindness. So, do you think that might be more along the lines of Sorcery?
