It is the Hardest Mini Boss because of his Armor, but I used a High level Velonasaur with melee point and I took him down, an army of magmasaurs or rock golems could probably do it to, maybe a Yutyrannus can improve your chances. Up if you found helpful.

I have killed him four times without issue cryo pod an imprinted giga good stats 500ish damage 30000ish health. Also bring very good cold weather gear a tec canteen with hot water really helps and curry. Your biggest pain will be picking bear guts from your gigas teeth for hours.

20 1k Maylee shadowmanes each doing 50 damage

U was there for 2 hours

Corner ledge, velonasaur, 25 minutes of ur life. Steinborn = dead

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

Alright so Heres a good tip.

Noooo u dont need mutated gigas or rexes, u just need a velonasaur(from the fire wyvern island), crank up to abt 600%+ dmg and use a grapple to get on one of the ledges and then just shoot him from the cliff, he cant get to u, therefor keep some health stuff like blood or brew, a few stones will hit u for small damage.

Use runestones from alpha creatures to summon it in, in Jotunheim.

Third tip! It’s cute. No? Is it just me?

Blood stalkers have a amor piercing attack so use some front blood stalkers

Gigas are the way to go, rock elementals do the second most damage against it.

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

Your best bet is something that deal explosive damage like magmasaurs or shadowmanes not only are the not affected by the bears armor but they deal extra damage. Phoenix does as well but unless you have an army of god tier phoenix I do not recommend it.

The magmasaur is hit strong

A good way to defeat this bear is to use velonosaurs as they do enough damage to bring it down, you can also use gigas and rock elementals. If your on your own without dinos you can use a rocket launcher with homing missiles while being grappled to a wall with a crossbow and grapples as this works quite well too..

You cannot tame-björn the stein-björn

Fly to ledge at the back of the cave in then un cryopod a descent velonosaur. Bring milk.

second tip! Different person!

forcetame to own god

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

Use Velos on the cliff with vines, use climbing picks or grappling hooks and if you position your velo correctly it can’t hit you. Try to bring a friend and you both have 140+ wild tamed velos with like 4k+ Stam and good melee

To kill use the amargasaurus armor break spine to remove the damage reduction and then kill it with gigas
