Vampiric Curse

Unlife: Your aging slows to a halt and you are unable to continue aging, by any means, until the curse of Vampirism is removed. You also no longer need to eat, breathe, or sleep, though you may if so inclined. You receive the full benefit resting as long as your eight-hour rest only involves light activity.

Forbiddance: You find that you may not enter a residence without the explicit invitation of somebody current inside. A public building with open hours listed, or sign on the outside of a building saying something like "open for business", will also allow you to enter a building. Any attempt to enter a building without permission will result in 1d10 damage per minute inside. If you are explicitly forbidden entrance, you will find an invisible, unbreakable wall that prohibits your entry, though not attacks.

Running Water: Running water deals 1d10 acid damage per minute, or per round at the beginning of your turn if in combat. This damage ignores all resistances and immunities that may be granted otherwise.

Stake to the Heart: If a piercing weapon made of wood is driven into your heart while you are incapacitated or in a place of rest, you become incapacitated until the stake is removed.

Sunlight Hypersensitivity: Your eyes have been altered for night hunting. You have darkvision up to 120 feet and when in direct sunlight (and not wearing any items to lessen the intensity of the light) you can only see up to 60 feet away. While in bright sunlight, you have disadvantage on attack rolls.

Passing the Curse: As a Vampire, you are to turn another person by drinking their blood, having them drink your blood, and then killing them. When buried, they will arise at midnight as a new Vampire.

Vampiric Bite: Your fangs extend and you are able to use a Vampiric Bite as a natural weapon, dealing 1d6 necrotic damage. On a failed constitution save, the vampire may steal that vitality for themselves. This is increased to 1d8 at level eight and 1d10 at level twelve. At level sixteen, you may use your Vampiric Bite as a Bonus Action.
