With this mod activated:
You'll learn vampire powers from spell tomes instead of the spell, Allowing you to choose what power you want to learn without Vampirism.
Also files are separated, you can choose which file to activated.
Fear = Vampire drain
Frostbite = Vampire cloak
Healing = Vampire charm
Muffle = Vampire muffle
Sparks = Vampire hunter sight
Soul trap = Poison resist
Lesser ward = Raise thrall
Clairvoyance = Vampire strength
Bound Sword = Sun damage(if wanted!)
Flames = Embrace of shadows
-----
You can disable the mod permanently after learning the powers, no problem will occur.
