This Metaplast Mace has been reformed. A normal Metaplast Mace has a plasteel core, surrounded by layers of metaplast. The inner layers draw heat from the outer layers, causing the surface of the mace to be super-cooled. The surface is hydrophobic, preventing liquids from freezing onto the outer layer of the mace. The cooling process has been amplified on this mace, and it causes considerable damage by flash freezing the flesh of anyone hit with the mace.
