When this spell is cast the illusionist creates a weaving, turning pattern of subtle colors in the air. This hypnotic pattern will cause any creature looking at it to become fascinated and stand gazing at it as long as the spell caster continues to maintain the shifting interplay of glowing lines. Note that the spell can captivate a maximum of 24 levels, or hit dice, of creatures, i.e. 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. The illusionist need not utter a sound, but he or she must gesture appropriately while holding a glowing stick of incense or a crystal rod filled with phosphorescent material.
