Beholders are beings of unbridled hatred and malice, despising all other forms of life. Each beholder regards itself as the pinnacle of being, regarding all creatures unlike itself as vermin worthy only of destruction. Beholders even hate each other, warring with one another even over minor physical differences.
Beholders naturally defy gravity, floating constantly in the air even when asleep. Each of their eye stalks possesses a different magical power and fires beams of magic that have different effects, including petrification, hypnosis, disintegration, etc.
