Vampire

Benefits:

• Undead Nature: You no longer age, don’t need to breathe, and are immune to disease.
• Blood Drain: You gain a bite attack (1d8 + Strength or Dexterity modifier, necrotic damage, this counts as a natural weapon with the finesse trait). If you hit a creature that is grappled, incapacitated, or willing, you regain hit points equal to the damage dealt.
• Vampiric Regeneration: At the start of your turn, if are not in sunlight or running water, you regain hit points equal to your Constitution modifier (minimum 1).

Drawback: You now have Sunlight Hypersensitivity: You take 20 radiant damage per round in direct sunlight and have disadvantage on all rolls while exposed.
