the bear is like a golem so use a velonasaur.

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

First tip! It’s a boss a help ful-

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

When spawned with commands and force tamed it is such a beast and one of the best boss tames ever its ice aoe attack is awesome

About 8 lvl 140-150 wild tamed gigas should do the trick

The hardest one of the worldbosses (imo) had crazy damage resistance when I fought it and had 300k health

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.
