Pit of Slaughter

Head to the easternmost part of Utgard in Jotunheim. You'll find a fighting pit with a Jotnar named Dugr the Bold. He's looking for a challenger, and when you agree to fight, he'll ask you to pick his shapeshifted form – a wolf, lynx, or bear. Don't worry too much about your choice, as he'll only transform into a rabbit anyway.

Once the fight starts, you'll need to take down a bear and a lynx. The catch? You can only use your fists! These animals will fight like they normally would in the wild, so watch out for the lynx's quick attacks and the bear's heavy hits. Keep an eye out for any attacks with a red or orange aura and dodge them. After dodging, you can flank the animals and land a few light and heavy attacks. It's a surprisingly straightforward fight.

After you've defeated the bear and lynx, you'll talk to Dugr again. He'll hand over a document with cryptic hints pointing to two wealth chests. The mystery concludes once your conversation is finished.
