the saddle may be a bit pricy early on but this creature is literally game-breaking. tame a scorpion, collect a lot of meat and wait for it to spoil, find a nice-looking high-level danger noodle and tame it while mounted in your scorpion (I recommend doing this whole process on the south cave, it's easier to navigate and to find the arthroplueras. taming the scorpion is a lot easier too, unless you get a bad layout). skidaddle your way to the cave of the strong after obtaining a fur set/resistance buff and literally farm the artifact with your arthropluera. it's not a fast mount so don't expect it to speedrun the cave, but it's the only way to cheese your way through the hardest cave in the game. the payoff is definitely worth it.
Very helpful, for caves and kill whatever you want! Because nothing will attack you. I bite a pteradodon he make he animation (ready to fly) but he stay on place and look at me! Same for giga I throw my poison, he too make his animation, but him also make his animation but nothing happens!!! (but just don't stay too near him, if he attack anything and you are near you too will takes the damages because he have a huge hit box) 🔺for other people see this!
