In Albanian folklore, the Lugat was a vampire that was invulnerable to any form of attack humans could use. Only wolves could inflict harm onto them. This vampire grows stronger with time, until about 30 years, when it reaches its full stage. At this point, in its life, the Lugat no longer has to return to the grave during the day, and can live in a home. The Lugat in its most advanced stage can sometimes be refered to as the Kukudhi.
