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

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

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?

Tame a saber and cave or look for bugs they get around 40 chitin per kill

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

You can use it as a smithy I got an Argy earlier today
