laughably easy to tame if you have a Pulmonoscorpius (any level will do). just go to south cave while mounted on a Pulmonoscorpius and tame the highest level Arthropluera you can find. if you have the amount of rotten meat needed (depends on the level of the creature but a few stacks of meat will get you there in no time) it's a free, high-level catch, that any early-game survivor can afford to tame (all you need is a Pulmonoscorpius which can be found in the same cave and is a easy tame)
