Don't know why you removed your thread, but if you wanna some ideas for the story you write and with the small description you write about "Biomancy", you can try to give a read to "I grow stronger by eating!" The mc have the capacity to shapeshift part of his body into thing he have eat, for exemple, he shapeshift his lungs into one of a dragon, his muscles into gorilla muscle, heart into a demon one, etc...
