Light Spheres (Su): As a swift action, a wyrd may create a pair of glowing spheres of intense light. These spheres may be wielded as melee weapons, and the wyrd may fight with one in each hand at no penalty. A sphere may also be hurled as a ranged touch attack, with a range of 60 feet and a 30-foot range increment.
A lesser wyrd's spheres are glowing red and deal 1d6 points of damage. A greater wyrd's spheres glow a sickly green and deal 1d10 points of damage and expose the target to its paralysis (see below).
Elves and undead creatures take half again as much (+50%) damage from a wyrd's light spheres, while elves or undead creatures particularly vulnerable to bright light (such as drow or vampires) take double damage. A construct or inanimate object takes only half damage.
Wyrds are immune to the effects of light spheres.
