Shellycoat

These river wraiths are the hostile spirits of those who have drowned in a river. While technically solid they are still ghosts.

The ectoplasm that makes them up is very sticky to everything except living flesh. This ends up with the Shellycoat being covered in shells, stones, and debris that act as a sort of protective shell.

The only exception is their feet, which allows them to walk without becoming stuck in place. It is possible to incapacitate a Shellycoat with a sparse coat by pushing them over, and sticking them to the ground.

It is unwise to use valuable weapons against the Shellycoat, as they are likely to become stuck. When the Shellycoat is destroyed, the ectoplasm fades.
