A spectator is an extraplanar beholderkin with four eyestalks. Somewhat mild and even-tempered, spectators have even been known to form friendships with other creatures, a trait that no other beholderkin or true beholder ever displays.
Like other beholders the spectator worships the Great Mother.
The four eyestalks of a spectator could cause effects like the spells fatigue, inflict moderate wounds, hold monster, and suggestion. Even more dangerous, the gaze of its central eye acted as the spell spell turning.
