The best caver. Change my mind. You can have them small to fit through tight gaps, you can put a little miner helmet on them for a light, allowing you to wear a gas mask or fur hat to survive better, they can climb walls and swim, they are super fast, they are super strong, and more. Their only limitation is the addiction and element required, but they’re great for short trips.
Ferox are amazing for travelling, they take no fall damage, can climb and scale walls, has a jumping boost if you time the jumps right upon landing, do good damage and if you take to extinction they can harvest the lampposts for element dust and are good for farming corrupt nodules, up so people can see!
