This creature looks like an animated humanoid skeleton, cold red light shining in its eyesockets and mouth. It wields an unnerving composite longbow crackling with black lightning.

An eldritch archer is a magically animated skeleton of an elven arcane archer that has been killed through exacting and foul unholy rituals. Several powerful osyluths are reputed to know the secrets of creating an eldritch archer, and they sometimes give favored mortal minions these secrets to aid in creating loyal guardians for particularly important sites.

Eldritch archers average about five feet tall and weigh about 60 pounds.
