Your Charisma score increases by 2, and your Intelligence score increases by 1.

Though related to Vampires, Dhampir are mortal. They mature a little faster than humans do though but can live up to 1000 years. Dhampir only withers with age in their last 100-200 years. Only the most secluded Dhampir achieve the feat of dying due to old age. 

Dhampir often tend to the lawful approach of their undead ancestors, preferring code and order rather than chaos. They do range from anywhere from good to bad though

Though taller and more slender then humans, the difference isn't at all extreme. Your size is medium.

Because of the dark conditions that your ancestors lived in, you have superior vision in dark and dim conditions. 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 colour in darkness, only shades of grey.

With the vampiric magic in your blood, you can shapeshift into a tiny bat for a number of minutes equal to your Charisma modified (minimum of 1).

You can use this feature again after a long rest. 

If you grapple a creature, you can attack them with an unarmed strike for 1d4 + your Charisma modifier necrotic damage as a bonus action. You regain back a number of hit points equal to the damage done (minimum of 1).

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

You also have vulnerability to radiant damage.

Thanks to your undead ancestry, you have resistance to necrotic damage.

You can speak, read and write Common and an additional language of your choice.
