I'd like some input on my Blood Hunter Homebrew

For the past few months I've been working on a remake or reimagining of the Blood Hunter class, basically I took the idea of a class that uses it hit points as it's class resource and made this.

At this point I'm just finishing off the Subclasses and the Blood Arts (you'll have to read the doc to find out what those are) but I hope to get them finished in next few months.
