With a megatherium(450% dmg) i got around 70 k chitin from running the swamp cave once on The Island,and with from(350 dmg) i got 2.5 k paste from one run.Of you willing to farm stone for cementing paste then megas are better, and if you are lazy then go with a frog or just farm bever dams.
Uhh, my last tip on cementing paste was actually wrong :/ RECAP: “HoW tO gEt MiLlIoNs Of CeMeNtInG pAsTe WiThOuT cOmMaNdS: StEp OnE: SuMmOn 99999999 MeGaNeRuA, tItAnOrYmA oR jUg BuG.” There are three problems with this. One, this many entities at once will crash your game, and maybe even some devices. Two, HOW ARE YOU SUPPOSED TO SUMMON THAT MANY IN A REASONABLE TIME?! Three, Summon IS a Command. Here is a fixed Version: How to get Thousands of Cementing Paste in a Reasonable Time without Commands. Step one: hop on your frog and head to the swamp cave (the artifact of the immune) Keep in mind there is toxic gas in there so bring a gas mask or scuba tank. I recommend scuba tank because it is less expensive. Keep an Equus outside the entrance with a high weight stat to carry it all. once you find a raving crowd of meganeura trying to nip at you, KILL THEM ALL FOR THEIR GLORIOUS PASTE! (araneo, arthropleura and pulmonoscorpius don’t give paste because too big) Also, Getting the artifact of the Immune as a bonus with your stacks of paste is optional, but i recommend it if you don’t already have it so you don’t have to get it later on.
I would say to raid beaver dams for cp. You can also get rare mushrooms, rare flowers and lots of wood.
If you have unlocked tranq arrows or darts, go into the swamp and tame a frog ( beelzebufo ) In the swamp, kill something and wait for insects to swarm it. Then kill all the insects with the beelzebufo and get cementing pace. Up if this was helpful
