In my typical tradition, after having made the Sorcerer Spirit Keeper origin, I ended up turning the thing into an entire class. I think the flavour and utility works a lot better as a class, but it’s also a very different play style to most of the other classes. A bit of warlock, a bit of beast conclave, the spirit keeper is all about using your spirit instead of doing things yourself. Hope people find it enjoyable, as I think the concept is a bit of a risk.
