Call me paranoid, although I would love to create new life willy nilly via animancy, I just don't know if I can afford the upkeep be it in energy or in social interaction. It is a characteristic in me that has grown over the years. Initially I was more into conjuration and summons etc. but the thought of so many different and possibly self interested high powered beings turning on me gives me definite pause.
The same could be true of necromancy of course but at least in that instance maybe I could just return them to the state of death etc. It may not be that simple. This is my own issue, meanwhile I love the idea of symbiotes so go figure.
