Taming data for the Steinbjörn is not yet available.
Magmasaurs, gigas, rock golems, and velonasaurs all do pretty good or so ive heard while pretty much anything else cant get past his armor
the bear is like a golem so use a velonasaur.
First tip! It’s a boss a help ful-
My tip on killing this boss is by getting 3 high level reapers and a yuty it is a powerful combo because of the damage and resistance
This boss has 300k health and has armor as tough as rock elementals so your best choice for taking him out are Gigas once killed it'll drop high quality loot
To summon it go to a cave around 77 30 in jotunheim and there will be a terminal where you can pay the required 30 runestones to summon
The hardest one of the worldbosses (imo) had crazy damage resistance when I fought it and had 300k health
About 8 lvl 140-150 wild tamed gigas should do the trick
Not sure if this is for everyone else but the dermis seems to be broken for me, it just shows up as a regular direbear and not the boss's form
Use runestones from alpha creatures to summon it in, in Jotunheim.
Steinbjörn is a boss in ARK: Fjordur.
