Vampire Spawn were the victims and subsequent creations of Vampires. Ravenous creatures with a vampire's hunger for blood, they were under the control of the vampire that created them. If a true vampire allowed a spawn to draw blood from its own body, the spawn transformed into a true vampire no longer under its master's control; however, few vampires were willing to relinquish their control in this manner. Vampire spawn became free-willed when their creator died.
Vampire spawn were dangerous foes in combat, even when fighting seasoned adventurers. They possessed unnatural speed and strength, sharp teeth and claws, and could climb as if they were a Spider. They naturally resisted nonmagical harm that came their way, and actively regenerated when not exposed to sunlight or running water.
There were many rumors on how to fight off or kill vampire spawn, but only some were true. Vampire sawn abhorred sunlight, as its touch burned them, as did copious amounts of running water. A wooden stake to a vampire spawn's heart would destroy it, if it was incapacitated in its resting place. Additionally, they never cast shadows or reflections, so any vampire wishing to move unnoticed among the living kept to the darkness and far from reflective surfaces.
