This page offers a guide on how to complete A Most Cunning Fish mystery found in Svaladal in the Dawn of Ragnarök DLC.
Where to Find A Most Cunning Fish Mystery
You can find this mystery on a small penninsula in the northeast region of Svaladal - just north of Gnafandi Keep. When you speak to the two dwarves, they’ll tell you about a big and cunning fish that has eaten their key and been terrorising the local waters. They have asked you to take care of the big fish and in exchange you’ll get to keep the key for their treasure chest (it contains a Platinum Ingot).
How to Find the Cunning Fish
Head to the water front and use Odin’s Sight to locate the fish nearby. Look for the largest fish and either throw out your fishing line or shoot at it with your bow. If you have decent aim, it’s definitely quicker to just use your bow and avoid the reeling in process.
If you’ve shot the right fish, you’ll trigger a cut scene in which the fish turns into a Jotun. The Jotun will give you the key but also tell you that he wishes to remain a fish because it’s a good life!
You can use the key to open up the chest nearby and claim the Platinum Ingot!
