By means of this spell the illusionist creates a pastel, glowing, rainbow-hued band of interplaying patterns. The effect is the same as a hypnotic pattern spell. However, once the rainbow pat- tern is cast, the illusionist need only gesture in the direction he or she desires, and the pattern of colors will move slowly off in that direction, at the rate of 3” per round. It will persist without further attention from the spell caster for 1-3 rounds, and all creatures (up to 24 levels or hit dice) subject to the dweomer will follow the moving rainbow of light. If the pattern leads its targets into a dangerous area (through flame, off a cliff), allow a second saving throw. If the view of the lights is completely blocked (by an obscurement spell, for instance), the spell is negated. The material components for the spell are a crystal prism and a piece of phosphor.
