Fog Crawler possesses a semi-solid form that allows it to phase through fog banks while maintaining a tangible presence when attacking. It can manipulate fog density to disorient prey and leaves temporary ectoplasmic trails that dissipate quickly. Its movements are silent and erratic, making it nearly undetectable until it strikes from close range. The creature is vulnerable to direct sunlight but regenerates in thick fog.

Fog Crawler influences events by patrolling fog-heavy areas of the course, forcing players to adapt their strategies to avoid sudden encounters and escalating tension during fog-thickening episodes.
