Why does a lawful creature with an Intelligence score of 17 spend its time lurking alone in dungeons? Shouldn't it be out conquering the world? This sourcebook, the seventh in the Complete Guide series, looks at beholders with a critical eye. It expands the ranks of beholder variants, gives their culture depth, and describes the nefarious beholder cults that spring up among humanoid races. Includes new feats, spells, and prestige classes, including details on how your characters can join a beholder cult and get eyestalks of their own.
