The Spiderbot Discharge Defense is a medium-sized, mechanical appendage designed for the Spiderbot, featuring a sleek, angular design with a central discharge node. The node is surrounded by a series of concentric rings that glow faintly when charged, set against a matte black metal body with visible circuit-like engravings. The defense mechanism has a slightly weathered appearance, with minor scratches and dents indicating field use, and emits a soft, electric blue glow when activated.
