When determining your character’s ability scores, increase one score by 2 and increase a different score by 1, or increase three different scores by 1. You can't raise any of your scores above 20.

Despite both undead and celestial heritage, the end result of the failed experimentation has rendered you mortal. Your creature type is Humanoid.

You are Medium or Small. You choose the size when you select this race.

Your walking speed is 30 feet.

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 only as shades of gray.

Due to your Aasimar lineage, you can manifest your wings a number of times equal to your proficiency bonus per long rest. When your wings are manifested, you have a flying speed equal to 30 feet so long as you are wearing no more than light armor.

Your wings take on the appearance of that of an angel's, but the ends of the feathers are always tipped red with blood.

You can manifest the wings as a bonus action, and dismissing the wings is a free action. They can remain manifested as long as you wish but you cannot remain airborne for longer than a minute and must land before performing any actions or bonus actions other than the dash, dodge or disengage actions.

Due to your vampiric parent, you gain no benefits from eating normal food. In order to sate your hunger, you must drink blood. This blood can be sourced from animals, but not only does it taste disgusting, you must drink it more frequently.

Animal blood provides the same benefits as a normal meal would, but humanoid blood will sate your hunger and provide you the benefits of having eaten for double that amount of time.

Additionally, you must still sleep and breathe as other humanoids do and gain no resistances against magical sleep nor benefits from an elven parent with Trance.

Unnaturally long claws or fangs are how you take the blood from your prey. You can use these as weapons against your foes as well.

Despite being rendered mortal, the spark of divinity that rests within you plays another cruel trick. You cannot become undead by any means. This means spells to raise your body into an undead automatically fail. You are immune to diseases that would make you become undead such as vampirism. You also cannot become undead through your own will such as becoming a lich.

You learned to speak the languages of your parents. In addition to Common and Celestial, select 1 language you would would have learned from your parents.
