Cool. We're up to the last of the beholderkin. This one is a bit wierd. It lacks eye rays, yet fires "arrows". I'm thinking we can simulate this by having it fire projectiles out of its eyestalks.

A 3-foot wide azure orb floats before you. Its chitonous body has a large central eye and smaller eyes dot its surface. Its mouth is wide and filled with needle-like teeth. Four hollow stalks move about, seeiming to track your movement.
Eagle eyes are mutant beholderkin created by Lycanth the Enlightented, a powerful wizard in the service of the dragon Abazigal. Because eagle eyes are created via experimentation on standard beholderkin, true beholders and their kin will attack them on sight.
An eagle eye is a 3-foot wide orb dominated by a central eye. Four eyestalks sprout from the top of its body. Unlike many beholderkin, its central eye serves no special function.
Eagle eyes speak the language of Beholders and Common.
Combat
Eagle eyes open combat with their bone arrows, and use their flight to stay out of opponents' reach while they continue to fire a volley of these natural projectiles.
All-Around Vision (Ex): Eagle eyes are exceptionally alert and circumspect. Their many eyes give them a +4 racial bonus on Spot and Search checks, and they can't be flanked.
Bone Arrows (Ex): An eagle eye continually produces small bone fragments which it can fire from its hollow stalks. It may fire up to four bone arrows per round.
Flight (Ex): An eagle eye's body is naturally buoyant. This buoyancy allows it to fly at a speed of 20 feet. This buoyancy also grants it a permanent feather fall effect (as the spell) with personal range.
The eagle eye first appeared in the Black Isle computer game Baldurs Gate II: Throne of Bhaal, (2001).
