 '''Rays''' are directional attacks produced by certain [[wand]]s, [[spellbook|spells]], [[horn]]s, and [[monster]] attacks.
-The ray attack is animated on screen, and a horn or wand will auto-identify if you are not blind. A standard ray will bounce if it hits a wall or a creature with [[reflection]]. Rays are halted by [[door]]s, although many will destroy the door in the process. The ray characteristics allow you to attack enemies without reply in the right situation. In the wrong situation you may be unable to use your powerful ray attacks for fear of shooting yourself.
