Witchlight( Ghostwalk, p. 39)
You can create witchlight, a harmless faint light, on yourself or an object.
Ectoplasm (Gh) ,
Greater Witchlight (Gh) ,
As a standard action, you can cause some or all of your body or an unattended object up to Medium-size that you touch to glow with witchlight, a harmless supernatural flame resembling faerie fire. Witchlight sheds light as a candle and may be pale red, orange, green, blue, or violet. Maintaining witchlight requires concentration, and you can maintain its effect on an object as long as it is within 100 feet of you. This is a supernatural ability.
You can use witchlight to outline a creature (such as one under the effects of blur, invisibility, and so on), but doing so requires a touch attack (which draws an attack of opportunity from the defender).
