The Spectral Stalker exists partially in the spirit world, making it nearly invulnerable to physical attacks. Only glow-in-the-dark discs charged with moonlight can harm it. It moves silently through shadows and can phase through solid objects. The creature emits an unnatural chill and causes electronic devices to malfunction when nearby.

The Spectral Stalker serves as a supernatural guardian of the rift's boundaries, preventing the Monster Hunters from accessing key areas of the course. It particularly harasses players attempting to retrieve lost discs in wooded areas after dark.
