Robotic Iron Spiders are an extremely rare species of mechanical contraptions consisting of junk metal walking on metallic limbs. They're equipped with maiming devices and tend to attack living things indiscriminately. Their kind can be mostly found in the Floodlands and Fog Islands but not much else is known about them. They can be found guarding intact laboratories.
- Being mechanical in nature, they require functioning electronic components to operate. If you bring one down and render it "unconscious," removing the electrical components from its inventory will kill it. If you manage to sneak up on one, you can stun it with a sharp blow, then finish it off in this manner.
