The Silt Serpent has a flexible, eel-like body covered in coarse, sediment-caked scales that provide camouflage in the creek bed. It moves with silent, undulating motions through water and silt, leaving minimal surface disturbance, and possesses enhanced senses to detect vibrations, along with a venomous bite that paralyzes prey, increasing danger during low-visibility rounds.

It patrols the creek's silt beds as an ambush predator, targeting players near water features to heighten survival tension and force adaptive strategies during fog events.
