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‘
This is by far the best gatherer of organic polymer. Carry the moschops to a frozen island with penguins. Put it on follow. Create a whisle group and whisle with the (Xbox) Lb down d-pad while looking at a corpse. It will collect the penguin corpse. Do not do this whisle in your base.
Easy Organic Poly method. Build a small pen with an auto turret in, set to short range and wild dinos. Put your Moschops in and then pick up Mantis and drop them in. The turret will kill them and the Moschops will harvest. I got 6000 poly in 30mins.
These things are freakin cowards. They will run at the first sign of danger. Make sure to carry with argy while using for maximum efficiency. If you trained it for gathering prime, put it in a tame order group of your choice, and whistle attack target on the dead creature while carrying it with argy/quetz, preferably a quetz because you can carry and attack at the same time, and fly close. Then once it harvests, fly home and enjoy the prime!
If you set them to wander they will harvest from any bushes or trees they come across, allowing you to passively collect huge quantities of fiber and thatch for crafting, aswell as berries for brews, beer, and keeping your animals fed. Also good for clearing out an area for building.
DO NOT PUT POINTS INTO MELEE DAMAGE
POINTS put into melee damage do not increase this creatures gathering efficiency. Speaking as someone who has messed up this way (23 times (have a nice little army going)) a much more useful investment is weight, maybe accompanied by some health.
Don't know why dodex took it off gathering charts but funnel in skills for a single resource and it is still number 1 gather, melee doesn't effect it put on neutral and wonder with victom harvest enabled to gather from corpses on normal days I get 40+ prime from a single stego. Carry with argie for safe harvesting
