Dhampyr's mature quicker than humans, reaching physical maturity roughly age 15 and can live for as long as they are not killed.

Your fanged maw is a natural weapon, which you can use to make unarmed strikes. If you hit with it, you deal piercing damage equal to 1d6 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike. You also gain hit points (minimum of 1) equal to damage done up to your maximum. 

When out of combat you can consume blood of any creature and choose to regain hit points (Minimum of 1) equal to 1d8 + your Constitution modifier once per long rest. 

You still need to eat and drink like other living creatures, blood acts as both a food source and water source. 

Dhampyr's do not need to sleep, but when taking a long rest you enter a conscious state of rest and maintain awareness of your surroundings.

When you are reduced to 0 hit points, you can make a constitution saving throw (DC 5 + the damage taken). On a success you instead drop to 1 hit point. You can't use this feature if your reduced to 0 hit points with radiant damage or a critical hit. After the saving throw succeeds, you can't use this feature again until completing a long rest. 

As a bonus action you can order the shadows to assault a target of your choice within 30ft. The target must succeed a wisdom saving throw (DC 12 + proficiency bonus). On a success nothing happens. On a failure the target has disadvantage on all rolls against you for the next minute. The target can attempt to remove the shadows by making another wisdom saving throw at the end of their turn. 

You can use this feature a number of times equal to your proficiency bonus. All charges are regained after a long rest. 

You can read, speak, and write common, the racial language of your mortal parent, and one extra language of your choice.
