Shanger was a goblin inventor who developed a tech-mod, called "Shanger's Scalder" entirely on accident. The mod added a series of superheated coils wrapped around an internal compartment filled with water. When the heating mechanism is activated, the water quickly boils over, producing gouts of steam that hiss from small jets all along the weapon's surface. It was usually filled with water, but virtually any liquid could be used, except flammable stuff. Rumor has it that he was trying to employ lamp oil in a modified warhammer when he met his unfortunate end. A dwarf engineer happened to find the "broken" weapon in a trash heap and refined the idea for his own use.
