The Elder Scrolls: BotSE - Fur and Fang Expansion

Lycanthropy affects those bitten with a transformational affliction. Werewolves succumb to a primal urge, and the ensuing frenzy is always a violent one. What they lose in sanity and control, they more than make up in sheer aggression and formidable strength… Using an Afflicted skill line, werewolves produce a heavy damage output in multiple battle forms, but they must transform in order to do so. When they transform, they’re unable to use other skill lines. Naturally, they will also induce lots of fatigue with such exertions. Created by Molag Bal and in direct conflict with your mortal soul, vampirism is commonly seen as a blight, as victims struggle against an insatiable thirst for blood. But the afflicted may find that such damnation results in a surge of power well worth the cost of their soul… Vampires, also an Afflicted skill line, do not rely as much on straightforward damage but have numerous vampiric abilities. Mist Form, Hypnosis, and other skills take advantage of playing a supporting role and establish vampires as creatures of the night! Something reaches for you from the dark. Will you grasp it?
