While dhampir do not need to consume blood to live, drinking blood does make them stronger. Some may forego drinking blood entirely as they cannot stand the pain they might cause, but some may lose themselves to the thirst. You can make a melee attack roll against a creature that is willing, grappled, incapacitated, or restrained. The target takes 1d6 piercing damage, plus 2d6 necrotic damage, the dhampir gains health equal to the amount of necrotic damage taken. You may use this attack once per short rest. 

As a result of their heritage dhampir are more resistant to necrotic energies and can forego food or water in favor of blood. Some understand that while blood is tempting it likely leads to problems, some know what blood can give them, and are more likely to seek it out. You have resistance to necrotic damage, in addition you may sustain yourself off of blood instead of food or water.
