Once per day, a cytillipede can cause the cytillesh patches that grow along its body to release a bright flash of blue light that provides bright light in a 20-foot radius and raises the light level by one step for the next 20 feet (treat this ability as a 4th-level light spell). Creatures within the 40-foot area of effect must succeed at a DC 22 Will save. Those within the 20-foot area of bright light that fail are stunned for 1d4 rounds. Creatures within the next 20 feet that fail are instead confused for 1d2 rounds. The save DC is Constitution-based and includes a +2 racial bonus.
