I think the name of the Natural Healer feature is a bit misleading as the Bloodsworn is not really a good healer himself just very adept at recovering. I would change the name just to clarify, possibly using a word like "vitality" or "recovery". It's a small nitpick, but I think it helps pin down the flavor of the class.

I also noticed that the class chart uses a different title than the features description does for the 5th level feature.
