Vampire abilities have been changed, too. You are given these at any stage, but they increase in effectiveness when you are at a higher stage.

Vampiric Sight:
- Improved night vision.
Given maximum duration to act as a toggled ability.

Vampiric Drain:
- Absorb 10 points of health per second from the target.
- Costs 20 magicka per second to cast.
Cost reduces at higher stages.

Vampiric Seduction:
- People up to level 6 won't fight for 15 seconds. Allows you to feed on the target for the duration of the spell.
- Costs 50 magicka to cast.
Turned into a spell instead of a power, so it can be dual cast. Effective level increases with stage.

Vampiric Invisibility:
- Caster is invisible for 10 seconds. Activating an object or attacking will break the spell.
- Costs 100 magicka to cast.
Turned into a spell instead of a power, so it can be dual cast. Duration increases with stage.

Vampire's Servant:
- Removed.
Nothing stops a vampire from simply reading a Raise Zombie spell tome.

Some miscellaneous changes:

- Sunlight debuff is now applied between 6:00 AM and 7:00 PM to better reflect when the sun is out.
- Feeding reduces your vampirism stage by 1, meaning it requires 3 feedings to get your stage from 4 to 1.
- Feeding on someone will give you 50% increased health regeneration for 4 hours.
- People you feed on have their health reduced by 25 points for 8 hours. You cannot feed on them again while they have this effect.
- People will attack you on sight if you reach stage 4.
