Bloodlust

You can drink blood from a willing creature, or one that is grappled by you, incapacitated, or restrained. As an action, you can make a melee bite attack against the target. If the attack hits, you deal 1d6 necrotic damage. After supplying your body with the blood of another, you are able to walk in direct sunlight without imposing disadvantage on attack rolls or Wisdom (Perception) checks that rely on sight for a number of hours equal to half your Constitution modifier (minimum of 1). You may not benefit from this effect again until you finish a long rest.
