This mod adds two spells to the world. the first is Blood Gorge which is a more powerful life drain spell that allows 50 points of health per second, as well as magicka and stamina (it was designed for a vampire play-through hence the name). The second spell is called wall of pain and is very OP or a god spell that combines all three elemental wall spells into one doing 300 damage per wall spell (around 900 damage). Both of these tomes can be found by the guard tower in Whiterun right next to the Barracks.
