At higher levels with at least 2.5k health and melee it is the most unexpectedly useful small cave mount. It has a huge attack radius, including directly behind it, and if you pump up it’s melee it can 1 shot a flock of bats or piranha in a single bite. High torpidity pool and drop, regains health rather quickly as well. Oh, did I mention it can gather around 300 chitin per spider harvested? About double that much from Arthropleura. Dump points into prime meat harvesting and you’re gonna be FULL of prime to tame carnivores. Just make sure to NEVER dismount mid-fight and bring a strong shoulder mount as insurance in case you get pounced off by something. You’re welcome.
Feeding it what you want it to gather has NO EFFECT on its father rates. These are determined by the additional level granted every level to increase your moschops' gathering efficiency of your chosen resource.
Best for if you need fast polymer for crafting. I have used this countless times to make all the industrial equipment. But only level up health and weight and put the gathering levels into polymer. Mines at 530% and I get 50 polymer per penguin. ðŸ‘
