Hypnotic Pattern

When this spell is cast, the wizard creates a weaving, twisting pattern of subtle colors in the air. This pattern causes any creature looking at it to become fascinated and stand gazing at it as long as the spellcaster maintains the display, plus two rounds thereafter. The spell can captivate a maximum of 24 levels, or Hit Dice, of creatures (for example, 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. A damage-inflicting attack on an affected creature frees it from the spell immediately. The wizard need not utter a sound, but he must gesture appropriately while holding a glowing stick of incense or a crystal rod filled with phosphorescent material.
