Unburied Archer Ghost

In one haunted river basin, and in lands like it, people who die without due burial often linger as ghosts bound to the spot where they fell. Each looks much as it did in life, only see-through, and every one of them carries a bow and quiver.

Normally the ghost rests on the Ethereal Plane. When intruders disturb its haunt, it turns semi-material, and therefore visible, and shoots spectral arrows at them. These hit automatically, with no attack roll. The target catches a disease unless it saves vs. spells, generally the deadly kind (see cure disease). Succeeding on that save makes the character immune to that particular ghost. One who fails will keep failing every save against it until gaining a level, which restores normal chances.

In its half-solid state only silver (for half damage) or enchanted weapons (for full damage) can hurt it. On the Ethereal Plane it has AC 10, and spells affect it only when the caster is ethereal too. Having struck its targets, it simply fades back into the ether.

These ghosts ignore one another. Each is cursed to haunt its patch of ground until someone buries its body correctly, performs the proper rites, or otherwise lays it to rest. Sites of mass death may hold dozens.

Hard to wound and harder to destroy, the unburied archers are a very real menace. Local folklore warns travelers again and again to stay out of haunted places, one infamous site above all.
