These weapons emit beams of intensely focused light waves that resolve as touch attacks and deal fire damage. A laser can pass through force fields and force effects like a wall of force without damaging that field to strike a foe beyond. Objects like glass or other transparent barriers do not provide cover from lasers (but unlike force barriers, glass still takes damage from a laser strike passing through it). Invisible creatures are immune to damage caused by a laser weapon. Fog, smoke, and other clouds provide cover in addition to concealment from laser attacks.
