This boss is found patrolling the platforms in the first room. You can spot him by the lightning buff on him and the two iron dwarfs that accompany him. The lightning buff increases damage by a significant margin so you'll want to pull him on one of the rear platforms.

He patrols on the back half of the square. To get to him you need to clear the trash packs from at least three of the platforms. The shortest route is to clear the first platform, then the one immediately to your right, and then the back right platform. Wait for him to patrol back to that platform and fight him there. Time your attacks and only attack when his temporary electrical charge is down. This happens when he gets to the circles. It is generally easier, and faster, to kill him while the buff is on. This only increases his damage by a small margin on a well-geared tank, and is required for the achievement  Lightning Struck.

Bjarngrim is set up much like a warrior. About every 20 seconds during the fight he will change stances:

  • In defensive stance he hits the tank for ~1k and uses a knockback, an intercept, and a spell reflect.
  • In battle stance he hits faster but regularly, and uses a cleave.
  • In berserker stance he hits very hard and uses a mortal strike and a whirlwind. The mortal strike hits a well geared tank for more than 8k, and can crit for as much as 14k. When he whirlwinds he hits for about 1k (on plate) several times and will move around the platform. Well-armored characters can endure this attack but it is still better strategy to avoid it, and cloth wearers need to step out of its path.

He has two dwarves that accompany him. On normal difficulty, they have approximately 45000 health. They should be killed first as they can heal him if left alone. They can also be feared, slowed, polymorphed, sapped and trapped.
