Mechanism: "Diligence" Class Drone
Rogue maintenance unit.
Roving mechanoid with energy-based attacks. Vulnerable to dark energy. The Diligence drones were the first cleaning units designed by the Luminoth. They were modified for combat duty once the war began, but were outshined by the newer Harmony-class units. A Diligence uses focused energy beams to perform its duty. Their energy construct nature makes them invulnerable to most attacks, though dark energy can disrupt them.
