So i have been having a bit of a dilemma in my RP recently. I have a friend who says his vampire character does not have to breath at all because he is a vampire and is undead yet he fights the notion that a necromancer would not be able to control his undead vampire body. I was wondering what all of your feedback would be on this since i will admit i am not a professional when it comes to lore. So basically my question would be do vampires have to breath? and could a necromancer technically control one?
