I don't know this canon, but I read this and laughed because I have River Song, who thrives on chaos, and I've just added Sarah Bishop, who does not care what anyone thinks ever.

If she cares to be dragged out of her comfort zone in the future, I'm sure River could happily do that.

But more relevant to your actual requests, Sarah is a witch of a more traditional variety, so spells and potions and charms. And plants! She's particularly talented at healing, but she also has a good understanding of magic from her world and its architecture and function.
