You have established a greater degree of control over your sigils. When you concentrate, you can emit strong illumination from the glowing symbols that surround your head.
Prerequisite: Illumian.
Benefit: As a standard action, you can increase the illumination from your illumian sigils to provide a bright glow. Your sigils shed illumination equivalent to a daylight spell. The brighter light lasts as long as you concentrate, and for 1 round thereafter.
Normal: An illumian’s sigils ordinarily emit a 5-foot radius of shadowy illumination, equivalent to a candle.
