If I wanted to enchant something, I would cast a spell on it. Spells are the easiest for me, so I tend to use them in every aspect including healing by calling something out of someone and into the flame (hopefully it goes into the flame and doesn't hit me, it's still a learning process that I don't often use).
If your bound to this witch, maybe you should ask her if the energy comes from her?
If your connected to a "powerful" (I really don't like that descriptive word, it sounds arrogant) witch, why don't you just join her family and coven?
I have noticed many people with disabilities are good with the arts. They struggle in the real world with socialization, but the arts are surprisingly easy.
