Rainbow Pattern

This spell functions as hypnotic pattern, except that it affects up to 24 HD of creatures and the caster may move the pattern by up to 30 feet per round. If moved, all creatures under its effects will follow the flowing lights, trying to keep as close to it as possible. If any affected creatures move into a dangerous area, they get a new saving throw. If the view is moved out of sight of an affected creature, they are not longer affected. This spell will continue for 2 rounds after the caster stops concentrating on it.
