This Bulgarian vampiric revenant is created when a person dies a sudden and violent death and the spirit refuses or does not realize it needs to leave its body.
After 40 days the vampire will dig itself free from its grave and begins a reign of terror though this mainly consists of smearing manure on the sides of a person’s home and breaking the dishes in his house.
Active only between noon and midnight this vampire will exhaust all other food sources and options before seeking out a human to attack for his blood. If the person can make an offer to the vampire to spare their life the vampir must accept.
The only one with enough skill and knowledge to destroy this type of vampire is a Vampirdzhija (a type of vampire hunter).
