A Castellax-class Battle-Automata outfitted with Shock Chargers on its manipulators.
The Shock Charger was a weapon employed by the combat robots of the Adeptus Mechanicus' Legio Cybernetica to enhance their abilities in melee combat. These weapons added a powerful electrostatic discharge which detonated like a thunderclap whenever the robot struck a target.
