Be ready to destroy your mental health while trying to get this stuff. It will not be so easy if you're alone.

Never stop crafting this. Just when u think u have enough, and want to craft something, turns out u need 500 more

Why does the obsidian have to be so heavy!!!!

On Fjordur there is a cave called The Shimmering Halls located at 12.5 62.6. In this cave you can harvest polymer from boxes that spawn by a anvil found in the cave. There is a bridge that goes straight and right. It is on the right. These boxes respawn and give you polymer, metal, and obsidian.

DO NOT TURN OFF YOUR FABRICATOR WHILE YOU ARE CRAFTING SOMETHING IN IT! WORST MISTAKE OF MY LIFE!

ARK MOBILE: This method is preferable for single player as youll receive 100% of your materials back if you destroy a structure. What you want to do is grab yourself some clubs and go kill as many penguins as you can for organic polymer. You then want to place that organic polymer in a fabricator and make vaults - I typically do around 4- Destroy them and instead of recieving organic polymer, it’ll be converted to regular polymer. Repeat the process :D

Organic poly will work instead of regular poly if you’re in a pinch. Otherwise just craft it with obsidian and and cementing paste in a fabricator.

Downvtoe all tips that say to craft vaults using these then destroy it to get "100% of the materials back". No. That is not how the game works, you are playing on Casual mode, which is not vanilla, while every other ark player is playing normal mode which is the way the game is intended to be played so if they destroy structures they will only get 50% of the materials needed to craft back.

For the cementing paste Just Tame a frog and do the redwood cave(ive done it and i filled a whole vault with cementing paste)

On ark mobile, if you are on casual difficulty you can use an achatina to get organic polymer by logging out then back in, then craft something with a fabricator with the organic polymer.(make sure you have enough of the other resources and make sure to make 2)Then place 1 then the other (i used elevator track), then get 1 of them back (there is a short time where you can pick up the structure without destroying it) then destroy the other one. You will get polymer instead of organic polymer. Rinse and repeat and you have virtually infinite polymer.

Repeat the process :D if you are playing on casual mode instead of normal mode (the mode the game is intended to be played on)
