Hm. Okay. I figured I’d ask. But I’ll see if Asetenarra or James have anything like that. I’ve used blood magic with my own blood for a protection amulet of sorts. It doesn’t work on everything, however. There were creatures prior that didn’t seem stopped by magical barriers. We have tattoos triggered by blood if we’re in danger - the coven - but I think something with less bloodletting and maybe simpler would work better.
