A Beholder is an aberration comprising a floating spheroid body with a large fanged mouth and single eye on the front and many flexible eye stalks on the top. A beholder’s eyes each possess a different magical ability; the main eye projects an anti-magical cone, and the other eyes use different spell-like abilities (disintegrate objects, transmute flesh to stone, cause sleep, slow the motion of objects or beings, charm animals, charm humans, cause death, induce fear, levitate objects, and inflict serious wounds).
Many variant beholder species exist, such as “observers,” “spectators,” “eyes of the deep,” “elder orbs,” “hive mothers,” and “death tyrants.” In addition, some rare beholders can use their eyes for non-standard spell-like abilities. These mutant beholders are often killed or exiled by their peers. Beholders wishing to cast spells like ordinary wizards relinquish the traditional use of their eyestalks, and put out their central anti-magic eye, making these beholder mages immediate outcasts.
Different breeds of Beholders have different magic abilities. Beholder Eyes of Flame only have Fear, Fire, and Telekinesis Rays. Eyes of Frost are the same, with fire replaced by frost. The Beholder Eye Tyrant is mostly unchanged from traditional beholders, but the Death Ray causes ongoing necrotic damage rather than an instant kill, and the Disintegration Ray does not automatically kill its target. Other Beholder types each have their own set of abilities.
