So I saw the new Spirit in the new Doom Eternal expansion, and thought I'd try it out. Just a rough concept, to see if I can get possession itself working. Currently, it'll possess any monster that has more than 200 health (so it doesn't waste itself on meaningless trash monsters), a monster can only be possessed by one Spirit, and it doesn't really get any benefit right now (but those are really easy to add).
