City of the Spider Queen
These undead abominations are creatures of pure hatred and malice, filled with loathing for everything that lives. Though a drider vampire drinks blood and has other abilities that resemble those of a common humanoid vampire, the two are actually quite different creatures.
A drider vampire looks much as it did in life, with the head and torso of a drow and the lower body of a drider. Its hands are wickedly clawed, and from its mouth protrude huge fangs like those of a venomous spider.
