The creature is nothing more than an orblike, bulbous body with green chitinous scales, and a large maw filled with viperlike fangs. Writhing, hissing snakes sprout from the top of the orblike body, and its central, unblinking eye is yellow and reptillian.
Gorgon eyes are mutant beholderkin created by Lycanth the Enlightented, a powerful wizard in the service of the dragon Abazigal. It is rumored that the essence of medusae were mingled with that of a beholder to create this monstrosity. Because gorgon eyes are created via experimentation on standard beholderkin, true beholders and their kin will attack them on sight.
A gorgon eye is an 8-foot-wide orb dominated by a central eye and a large, toothy maw.
Gorgon eyes speak the language of Beholders and Common.
Combat
The gorgon eye uses its petrification gaze to deadly effect, and attempts to poison those who resist.
Petrifying Gaze (Su): Turn to stone permanently, 60 feet, Fortitude DC 17 negates. The save DC is Charisma-based. Once each round, during its turn, the gorgon eye decides whether its petrifying gaze is active or not (it deactivates the gaze by shutting its central eye).
Poison (Ex): Injury, Fortitude DC 20, initial damage 1d6 Dex, secondary damage turn to stone permanently. The save DC is Constitution-based.
All-Around Vision (Ex): Gorgon eyes are exceptionally alert and circumspect. The many eyes of their snakes give them a +4 racial bonus on Spot and Search checks, and they can't be flanked.
Flight (Ex): A gorgon 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 gorgon eye first appeared in the Black Isle computer game Baldurs Gate II: Throne of Bhaal, (2001).
