monsters on the south cave won't attack you if you're mounted on a Pulmonoscorpius. they won't even move, even if you attack them. that means that you can tame a low-level Pulmonoscorpius (they're easy tames since they're so slow) and farm Titanoboas and Arthroplueras for loot and experience (i suggest pumping all points into attack, for obvious reasons). unfortunately it won't fit through the passage of the last area (where the artifact is located), but you can simply kite the other Pulmonoscorpius and easily dispatch of the Araneos, in order to retrieve the artifact. a game-breaking early tame.
