I'm kind of trying to move around the different aspects of my character, and especially work out how his magic would work. Basically, he would be a golem created by this 500 year old wizard, who has recently died because of insanity. He would be a gadgeteer, and would eventually be able to modify himself, though one of the caveats would be that he would need a master in order to allow interpretation of his user manuals.
So I guess his magic would be equal mixes alchemy and... sigilism? Whatever making magical objects would be.
