Assassin's Creed Valhalla: 10 Secret Bosses You Must Find
4. Nokkfylla Shine-Eye
While exploring the most northern part of Eurvicscire you'll find old Nokkfylla Shine-Eye rambling on about being lost and unchained. And if you're below the recommended power threshold of 280, it's probably best that you leave this crazy drengr to his own devices until you're able to present him with a worthwhile challenge.
That being said, if the hero inside of you calls you to stop the unnecessary bloodshed of the innocent, you might have no choice but to send him off to Helheim as soon as possible.
To immediately put Nokkfylla on the backfoot use a heavy attack to knock him from the platformed area, as this will cause him to lose his footing and fall. You will then be able to run in and perform a stomp for big damage, as well as cleave him with attacks until he gets back on his feet.
Other than this, using your offhand attack ability to inflict a flurry of blows on the drengr will prevent him from being able to attack. But remember to always keep enough stamina to dodge away, as his runic attacks can't be stopped and take you down to a sliver of health in the blink of an eye.
