Dhamphiri's [Also known as Dampires] are half-human, half-vampire. In some sources, Homo Sapiens Dhamphiris Nocturna is the technical name of these creatures.
In Serbian mythology, they are the child of a Vampire and his Widow. It has been said that Dhampiri's often have powers similar to a Vampire, but none of their weaknesses [Although the reverse can occur, as well]. Dhampiri's are also believed to be unusually adept at killing and detecting other Vampires.
