Unholy Body. Dark magic sustains you, making you resistant to necrotic damage. Healing potions do half of their healing effect on you.You can also heal by either drink blood, spend hit dice, or finish a long rest.

Blood Drinker. Even though you are undead, you still require sustenance in the form of blood to sustain your unholy existence. You are immune to diseases. You do not need to eat or breathe, but you can ingest food and drink if you wish. If you go for longer then fourteen days without drinking at least one ration of blood, you suffer one level of exhaustion on the midnight of that day, which can only be removed by drinking a ration of blood. After consuming one ration of blood, you recover all levels of exhaustion. If you reach six levels of exhaustion due to this trait, you are destroyed.

Darkvision. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of gray.

Bite. All dampyrs have sharpened teeth capable of tearing flesh from bone and draining blood from the body. If a willing, paralyzed, charmed, incapacitated, restrained, or grappled, creature within 5 feet of you has blood, you may use your bonus action to Bite them dealing 1d6 piercing damage and draining their blood dealing additional necrotic damage equal to your Constitution modifier. Drinking blood this way is equal to consuming a ration as per your Blood Drinker trait. When you use your Bite, you can choose to not deal damage.

Blood Connoisseur. As per your Blood Drinker trait, if you reach six levels of exhaustion due to this trait, instead of suffering death, no longer gain any more levels of exhaustion and become indefinitely paralyzed. The only way to remove this paralyze is to be exposed to a rations worth of blood.

Superior Darkvision. Your darkvision increases to 120 feet.
