Rainbow Pattern

By means of this spell, the wizard creates a glowing, rainbowhued band of interweaving patterns. Any creature caught in it may become fascinated and gaze at it as long as the effect lasts. The spell can captivate a maximum of 24 levels, or Hit Dice, of creatures—24 creatures with 1 Hit Die each, 12 with 2 Hit Dice, etc. All creatures affected must be within the area of effect, and each is entitled to a saving throw vs. spell. An attack on an affected creature that causes damage frees it from the spell immediately. Creatures that are restrained and removed from the area still try to follow the pattern. Once the rainbow pattern is cast, the wizard need only gesture in the direction he desires, and the pattern of colors moves slowly off in that direction, at the rate of 30 feet per round. It persists without further attention from the spellcaster for 1d3 rounds. All affected creatures follow the moving rainbow of light. If the pattern leads its subjects into a dangerous area (through flame, off a cliff, etc.), 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 wizard need not utter a sound, but he must gesture appropriately while holding a crystal prism and the material component, a piece of phosphor.
