What powers do you think a witch of mind would have? I normally think of being able to shift the consequences of people's actions

Shifting the consequences of people’s actions doesn’t sound too likely, since the consequences seem more like, a chain of causality stemming from a choice. Rather, they’d sway what choice they take, which leads to a change in their actions. Of course they’d also be able to Change other peoples’ Minds, may sway opinions and ideas, alter memories and thoughts, and change how others perceive someone or how someone shows themselves to others. Witch and Mind, too, sounds like an extremely logical and rational person. Kinda robot-like.
