I have an idea for a witch and an elf's child, but I had a question stuck on my mind. Would it be possible to have a character who, along with your typical hoodoo (the stuff that's common among the witches), has Energy magic? I was thinking about using it as a mechanic for character development in the case of a character who needs to learn self-discipline and self-control. If such a rare case were feasible, what sort of implications would the character run into, and what sort of things could the character become capable of?
