Use a moschops and put organic poly in harvesting level then kill a mantis or anything that drops poly and it should give a lot. Roughly 60 levels in the harvesting level gives about 800 to 1.2k poly per mantis on small tribes rates
Taming an Achatina (the snail) is a good way to farm organic polymer since after taming it it will produce 100 cementing paste and 100 organic polymer after a certain amount of time(only after being set to wander). And for me it seems that they will be content to just eat out of a feeding trough instead of eating exclusively cakes so it is a good way to farm both items with relative ease. And you can store it into a kairuku or some other tame to store it before you start to craft something.
To the guy that said that using a hatchet in the bee cave on crystal isles, no, using a hatchet gets far less organic polymer than the chainsaw, using the chainsaw will get you a lot more organic polymer than anything else that I have tested.
To that guy from oct 2020, Hey o it’s me that guy who wrote the conv. Method, (blackout is my name btw) um the method is still functional and I jus tried on my single player casual save and the method is still working. I don’t think that the method is broken but here are a few things to note.
1: ONLY works on casual
2: Most servers aren’t casual
3: you may have forgot to take out the normal polymer
Can be created by achatinas (snails) like the dung beetle creates oil but you dont feed it anything it will create polymer overtime dont eat it it will instantly kill you no it wont give super powers its a lie
Tame achtinas, Low level will be good then bigger, so tame low level, they also can preserver organic poly and also produce it in their inventory! I opened a acha Tina farm lol. So much CP and Organic poly!!
Don't know if this works on all versions, but if you're looking for a way to store it, the large snails will apparently double or triple the shelf life when it's in their inventory. Just don't forget to feed the snail a veggie cake every now and then.
Make sure to do the pursuit that gives you an ascendant sword, I believe it's the pursuit where you have to kill raptors or the one where you have to kill terror birds. With the ascendant sword and higher damage the sword produces, you'll get more polymer.
