The Piecemaker is a powerful siege crossbow edited into the most awesome sidearm ever used in law enforcement by none other than Sergeant Detritus the Troll himself (granted, Mister Vimes has explicitly forbidden its use in most cases).
Powers and Stats
Tier: At least 9-A, possibly 8-C
Name: The Piecemaker
Classification: Modified Siege Weapon
Prerequisites: Capability of lifting a car and using enough energy to pull back the draw (estimated 20,000 lb draw if compared to a typical 20 lb crossbow)
Attack Potency: At least Small Building level, possibly Building level (Said to be able to shoot through a building's front door and exit through the back door or, if there is no back door, it'll make one)
Range: 460m if compared to similar weapons (ballistae)
Note: This weapon is similar to a shotgun, as it fires over a wide range via using twenty 6-foot lances as arrows all at once. These lances, however, shatter, and become fiery bits of wood, tearing apart everything in sight.
