A semi-legendary monster - seasoned stalkers describe him as a tall, stooping humanoid with many tentacles in place of his mouth. According to them, with the help of tentacles, this creature feeds: by digging them into the neck of a living victim, it paralyzes its prey and sucks its blood; after such a procedure, only a dried-up, mummy-like shell remains from a person. The most amazing thing about a bloodsucker is his ability to become invisible. Apparently, these creatures are responsible for the death of a large number of stalkers. Few of the eyewitnesses survived - and, judging by the stories of these lucky ones, bloodsuckers prefer damp places like swamps and dungeons for habitation.
