A copper-red ray bursts from your outstretched hand. The sound of grinding gears and breaking metal accompanies the ray's flight.

This ray interferes with magical animation, degenerating the magic bound within constructs and effectively causing damage. You must succeed on a ranged touch attack with the ray to strike a target. The ray deals 1d6 points of damage per caster level to the subject (maximum 15d6).
