You can still eat bodies (heals you rather than gives a permanent buff), you can shoot necrotic bolts that kill with high efficiency and give a ton of pain to the target, you can fly to rapidly cross a huge area, and we just got you to learn a scroll that allows you to drain mana from enemies (mages lose mana, if they don't have magic then you suck down life force instead). Without scrolls, you can learn to create a fog that functions as an AoE death bolt, explode corpses, and mark enemies for death (while also ******* with their willpower to continue fighting- make them worse while increasing your damage with death bolt against them).
