"The pistol is engraved with watervine hemp and encircled in saltstone. On the grip is an image of a nomad and knight in saltstone. The knight is striking down the nomad."
Like all laser weapons, it deals Light Damage and heat damage making it useless against enemies with 100 heat resistance.
The description of the item may be a reference to Dwarf Fortress, as the item descriptions of Dwarf Fortress follow an identical structure to that of the Laser Pistol.
