This page offers a guide on save Ylva in the Dwarf in Distress mystery in Gullnámar, in the Dawn of Ragnarök DLC.
How to Save Ylva
Ylva is found west of Hvergelmir Mylna near the regional border. When you approach the area, you’ll be attacked by wolves. The wolves can also shapeshift into Cutthroats so make sure you’re prepared to dodge not only wolf lunges but strong warrior enemies too!
Make sure when a warrior does pop out that you focus on them and then the wolves because they can do a lot of damage. But, make sure to dodge the wolves’ power attacks and lunges whilst you focus on attacking the cutthroats first.
Once you’ve taken out all the wolves/cuttthroats, you’ll be able to find Ylva hiding behind the large rock nearby. She’ll give you another clue to the Suttungr’s Outrider Vesalligr and she’ll also tell you to meet her again at Grenhellir Shelter.
When you meet her at the shelter, she’ll reward you +150 Silver, +10 Titanium and +100 Leather.
