Dhampirism

Dhampirs often arise from encounters with vampires, but all manner of macabre bargains, necromantic influences, and encounters with mysterious immortals might have transformed you, granting you the following benefits:

Death's Kiss. You are an Undead in addition to your other creature types.

Eyes in the Dark. You gain darkvision out to a range of 60 feet. If you already have darkvision from your race, its range increases by 30 feet.

Supernatural Resilience. You have advantage on death saving throws.

Vampiric Bite. Your vampiric bite is a natural weapon, which counts as a simple melee weapon with which you are proficient. You add your Strength, Dexterity, or Constitution modifier to the attack and damage rolls when you attack with this bite. It deals 2d4 piercing damage on a hit. If the target is willing or unconscious, you can choose to forgo this damage.

When you attack with this bite and hit a Humanoid, you can empower yourself to regain hit points equal to the piercing damage dealt by the bite and gain a +1 bonus to Attack Rolls, Saving Throws, and Ability Checks until you finish a long rest. The creature you bit has a -1 penalty to Attack Rolls, Saving Throws, and Ability Checks until it finishes a long rest or has lesser restoration cast on it. Once you use this feature, you can't use it again until you finish a long rest.

Sanguine Diet. In order to receive the benefits of a long rest, you must have consumed 1 pint of blood within the last 24 hours.
