If you’re on mobile, sabers are good for harvesting chitin. Go into the south cave (the easiest one) and you’ll come out with thousands of chitin.

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

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

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

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

Kill bugs to get the most chitin

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

There should be a TEK variant that allows fabricator/TEK level items to be built
