Is it possible to reverse a blood magic spell? And what would one of these spells look like? Say for instance a person has a certain thought in their head and they scratch themselves and start bleeding, did they somehow cast in an irreversible blood spell?. I know it's a dumb question but I just would like to know. I realized your blood is your life Essence and this is nothing to play with. Some people say it can't be undone. But I beg to differ. have found different information on the internet. Thank you for your time
