You are Humanoid. When you are under the effects of Blood Starved your type changes to Undead.

Increase one ability score by 2 and increase a different one by 1, or increase three different ability scores by 1. If you are replacing your race with this lineage, replace any Ability Score Increase you previously had with this.

You can read, write and speak common and one rare language you would know.

You are Medium or Small. You choose the size when you gain this lineage.

Your Vampiric blood and evolved hunger has shifted your being from that of your original race, though some traces still remain. You can choose a racial trait from your original race prior to choosing this lineage. If no prior lineage exists or you chose this race at character creation, you may select an appropriate feat instead.

You have a base walking speed of 35 feet.

• Starting at 3rd level you gain a climbing speed equal to your walking speed.

While in sunlight, the Blood Starved has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.

At night time, you are a nocturnal hunter that excels at ambush tactics. Your steps are silent and any wisdom (perception) checks made to hear you is made at disadvantage.

Additionally you learn the Misty Step spell and can cast it once per day without expending a spell slot regardless of the time of day. You can only cast the spell in this way once per long rest, regaining the ability to do so after a long rest. You may also cast the spell using any available spell slots.

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 discern colors in that darkness as shades of gray.

You have escaped death, a fact represented by the following benefits:

• You do not age naturally, though you are still affected by magical aging.
• You have advantage on saving throws against disease and being poisoned, and you have resistance to poison damage.
• You don’t need to sleep, and magic can’t put you to sleep. You can finish a long rest in 4 hours if you spend those hours in an inactive, motionless state, during which you retain consciousness.

Your fanged bite is a natural weapon, which counts as a unarmed attack with which you are proficient. You add your Constitution or Dexterity modifier, instead of your Strength modifier, to the attack and damage rolls when you attack with this bite. It deals 1d6 necrotic damage on a hit. While you are missing half or more of your hit points, you have advantage on attack rolls you make with this bite. Succeeding on a hit with this attack is considered feeding for the sake of the Blood Starved effect and heals you for double your proficiency bonus.

Blood Starved Effect

You do not need to breath, drink or eat to stay alive, however you must feed on your chosen nutrients at least once a week or suffer 1 level of the Blood Starved effect. If you already have a level then your level instead increases by the amount specified to a maximum of 5.

For every level of Blood Starved you lose 1d4 character levels and one of your limbs wither and take on a mummified form. If all of your limbs are withered, you take on the physical form of a mummified husk and your creature type changes to Undead. Additionally, when completely withered, all creatures with the Lawful Good alignment will become hostile towards you.
If your level is reduced to below level 1, your level instead remains at 1 and you become completely withered, regardless of how many limbs you still have remaining.

Feeding resets your level and physical form as well as reduces the level of Blood Starved to 0.
