(clone only)

The sigils that orbit an illumian's head glow softly, providing illumination equal to that of a candle. Illumians can make their sigils disappear by concentrating for a moment (a standard action), but they don't receive the sigils' benefits and can't use any special abilities granted by illumian words (see below) while they're doused. Restoring the sigils to visibility is a free action. Luminous sigils (including power sigils; see below) are insubstantial and disappear into any matter they touch. An illumian's sigils remain present and in effect even when the illumian takes another form, unless she would lose her supernatural abilities as a result of the form change. An illumian wizard who casts a polymorph spell on herself retains her sigils, but an illumian who becomes a zombie loses them.
