Built by the prolific gadgeteer Arnesto Callahan. Built and designed in his own lab. One of a kind.
Firing the rifle has the same effect as casting Chain Lightning (lv6) effect as if level 8 caster, Cost 4 as it was built be an NPC. The gun has a flaw that Callahan could never quite fix, after being fired twice in an hour the gun gets very hot and must cool before being used. If a third shot made within the hour a vital part burns out. This will take an hour to repair, sucessful jury rig roll, and 1d4-1(minimum 1)x10 dollars in parts.
