Sunsword is a rather useful artifact long sword. It is lawful and does +1d5 to hit and double damage to undead monsters; L, M, W, Z, ghosts and shades. It also acts as a light source with a radius of 2 squares, and prevents blinding from lights. It becomes lit when wielded, and unlit when unwielded. If you kill a monster (except by stoning) which is wielding it, then it will stay lit, allowing you to use a different weapon while still having a light source. It has a 50% chance to be generated in the initial inventory of an Archon, and a 5% chance to be given to an Angel or Aleax.
