Radium Weapons are deadly and highly dangerous weapons that are used exclusively by the forces of the Skitarii Legions of the Adeptus Mechanicus. Radium Weapons are so volatile that they eventually kill their wielders. Their baroque beauty belies a singularly vile function -- not only to strike, but to render the battlefield as deadly as the rad-wastes of Mars. Each weapon's bullet cylinder is so thoroughly bathed in radium that a volley can cause a localised rad-storm. Those inside such a storm soon find their flesh blackening and sloughing away.
