Blood magic can be touchy, and any demon nearby is going to know I'm using it. They can't possess me without consent, so they can't come through if I don't let them, but they're going to start badgering me if they're here. Gives me nasty nightmares.
And I can't cast this sort of magic terribly often. I'll need time to recover between spells or I'll use up more blood than I have. Like I said, though, the upside is that I don't have to contact a demon directly, or we wouldn't even be talking about this. A friend of mine made extensive use of blood magic purifying and restoring a magical mirror and taught me a few things. If I'm guessing correctly, I'll be able to purify your organs and clean up the toxins. Regular healing magic just doesn't do that, it's better with wounds than illnesses. Chronic disease and sickness are things I can clear up, theoretically, but I need bigger magic than I use day to day, and the last time I called on a benevolent spirit, it got stuck in the physical world and was corrupted. It's too much of a risk to try that again.
