Your Charisma increases by 2. You may choose to increase either Strength or Dexterity by 1.

Dhampir reach maturity in their late teens like humans do and only then do their dhampir racial abilities manifest, which is called the 'change'. Once this occurs they no longer age normally and can live eternally.

Dhampir by nature will not be inclined toward a particular alignment but due to their need to feed and the reactions of people who find out about dhamphirs they often need to think of themselves first making them bend more to Neutral alignments.

Dhampir vary widely in height and build, from barely 5ft to well over 6ft tall. Regardless of your position in that range, your size is Medium.

Your base walking speed is 35ft, climbing speed is 10ft, "flying" is 5ft, and swimming is 0ft. You cannot fly as a humanoid, but you can jump. You cannot swim.

You can speak, read, and write Common and one extra language of your choice.

Thanks to your vampiric heritage, you have superior vision in dark and dim conditions. You can see in dim Iight 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.

You have advantage on Wisdom (Perception) checks to smell the presence of blood. This only applies to blood that is exposed to the open air, e.g. you can’t use this to detect a completely uninjured, hidden creature.

You have advantage on saves against the undead.

You are resistant to necrotic damage and cold damage.

You have disadvantage on attack and sight-based perception rolls that rely on sight when: you, the target of your attack, or whatever you are trying to perceive is in direct sunlight or bright light.

You are vulnerable to fire damage.

You can drink blood from a grappled, incapacitated, unconscious or restrained victim. If you do so, you gain temporary hit points equal to your Charisma modifier multiplied by 1/2 your level (rounded down).

You gain two actions from this trait:

• A scaling unarmed Fangs attack based on your level (1,5,10,15,20) that deals necrotic damage.
• A more "passive & simple" natural Bite, as a bonus action, that does 1+STR modifier piercing damage.

Rules:

• You do not need to eat or drink normal food or water. You must feed on the blood of a living humanoid creature once every two days. You can abate this somewhat by eating food and drinking as normal for a human everyday but only for up to six days before you must feed. You will be unable to abate your need of blood through normal food until you feed.
• When using Fangs: Drinking blood from an unconscious or incapacitated person has a 50% chance of killing them. Have the player roll 1d10, 1-5 the creature dies, 6-10 they live but can't be fed upon again or they will die.
• When using Bite: Whenever you succeed at grappling a target you can use your bonus action to immediately attempt to bite them. You automatically succeed on this attack if the target is willing.

Hunger

STAGE 1: If you skip one feed you become 'hungry'. There are no penalties for being hungry.

STAGE 2: If you skip a feed while already hungry you become 'famished' and gain 2 levels of Exhaustion. (Feed twice to remove.)

STAGE 3: If you skip a feed while 'famished' you become 'starving' and you receive an additional level of Exhaustion. You are unable to receive the benefit of a short or long rest . (Feed three times to remove.)

STAGE 4: If you skip a feed while 'starving' you become 'crazed' and receive another level of Exhaustion and you lose control - you cannot cast spells and you must attack the nearest humanoid creature you see regardless if friend or foe and attempt to grapple and bite them to feed which you continue to do while able until you feed. Attempts to grapple and bite will be made with advantage in this state. (Feed four times on separate living humanoids or kill one humanoid to remove.)

DEATH: If you skip another feed you die.

If you are not hungry and feed you lose one level of Exhaustion if you have any regardless of how you obtained it.
