You can get large amounts of keratin by killing carbs and trikes. Usually you want to get chitin instead since it is easier to get. Remember to use a hatchet to harvest it as a metal hatchet is the best early-mid game harvester of chitin and keratin.

A good way I found to get chitin is farming the scorpions with a axe you get like 120 -140 each

Why does it way 15 more pounds than all the materials to make it?

Works as a smithy but you can’t repair things in it

I tamed one before I got a saddle and I waited so long to ride it

Kill trillobits and you will get a lot of chitin

Do missions if you’re not the exact level or you can get loot drops you have a 1% of getting it or it just random. Hope it helps

Can also be used as a mobile smithy. Pretty handy, right?

just get a direwolf and go cave exploring or getting the artifact for a soothing balm before you tame an argy

got a crap ton of chitin from a single cave run with luna the direwolf
