Your physical form rests suspended between life and undeath, granting the following physical traits:

• Breathless: You do not need to breathe.
• Ageless: You are biologically immortal, do not suffer the frailty of old age, and cannot be aged magically.
• Resilience: You have Advantage on saving throws against the Poisoned condition and against taking Poison damage.
• Sustenance: You do not strictly require mundane food or water; your nutritional and biological need can be sustained entirely by consuming blood or utilizing your Vampiric Bite, if you so choose.
• Sleepless: You cannot sleep, and magic cannot put you to sleep. To gain the benefits of a Long Rest, you must spend at least 6 hours in an inactive, trance-like state, during which you remain conscious and aware of your surroundings.

Your lineage grants vision in lightless realms.

• You have Darkvision out to a range of 60 feet. Within that range, you can see in dim light as if it were bright light, and in darkness as if it were dim light. You cannot discern color in darkness, only shades of gray.

Your fangs are a Natural Weapon, which counts as a Simple Melee Weapon with which you are proficient.As a Bonus Action, it deals 1d4 Piercing damage on a hit, and you use your Constitution modifier instead of Strength for attack and damage rolls with it.

• Predatory Mending: When you hit a creature that isn't a Construct or an Undead with this bite, you can regain Hit Points equal to the Piercing damage dealt. You can use this benefit a number of times equal to your Proficiency Bonus, and you regain all expended uses when you finish a Long Rest.
• Desperate Siphon: While you have Bloodied status (half or fewer of your maximum Hit Points remaining), you have Advantage on attack rolls made with this bite.

Your vampire lineage allows you to effortlessly defy gravity:

• You gain a climbing speed equal to your walking speed (35 feet).
• You can move up, down, and across vertical surfaces and upside down along ceilings while keeping your hands completely free.

When your hands are free, you can lengthen your nails into sharp, twilight-tinged talons. Your Unarmed Strikes can deal slashing damage instead of bludgeoning damage, using your Strength modifier as normal.

As a short ritual of deep focus (which you cannot perform while in combat or incapacitated), you attune your senses to the scent and pulse of vitality around you. For up to 10 minutes (as if concentrating on a spell), you sense the presence, general direction, and rough quantity of living, blood-bearing creatures within 60 feet of you.

• This sense does not reveal their exact location through total cover.
• Creatures lacking blood (such as many Undead, Constructs, or Elementals) cannot be detected by this sense.
• If you enter combat, roll initiative, or make an attack or cast a spell, this focus immediately ends.

You can use this trait a number of times equal to your Proficiency Bonus, and you regain all expended uses when you finish a Long Rest.

Your body lingers on the threshold between life and undeath. The stillness in your veins leaves you partially numb to the decay of the grave, granting you resistance to necrotic damage.
