I have Dragonborn and Dawnguard mods. Im playing high elf. Im a normal vampire, and sometime I have Vampire Drain spell what is missile spell and drains 66 heal points and gives it to me. Sometime I have it, sometime not. I don't know what depens on that. When I feed I lose this power. When I don't feed for few days I lose it too. I want to have it forever. Maybe there is some cheat? Or I can have it without cheat?
