Ok, having been asked for this i am going to put it here. This is a little complicated. you are mixing here. Becoming any two entities you chose ie: Demon/angel, Werewolf/Vampire ect.... it is up to you but know that this is dangerous. extremely so. This can mess with your psyche as well. it is not something you should take lightly but if this is what you want it is inserted into your DNA and all future lives.
