Here’s a walkthrough of The Vengeance of the Berserker in AC Valhalla.
Suggested power: 20
This quest starts immediately after The Ritual Of The Berserker.
Follow Bjorn as he heads towards Beodoricsworth.
On the way there, you will encounter two soldiers. Take them out and continue towards the main base.
Inside Beodoricsworth, kill the soldiers until the Mercian lord emerges.
Kill the Mercian lord
The Mercian lord (Housecarl) will show up after some time. Kill him.
Leave with Bjorn
After the lord is dead, leave the area with Bjorn. It might take some time for him to leave as he keeps attacking the soldiers inside.
Once you’re outside the area, talk to Bjorn. He will tell you that Njal won’t make it.
Gather flowers for Njal
Next, you have to gather flowers for Njal. The flowers are located at the Gallows Tree, as shown in the map below. It’s south of Beodoricsworth.
Take the flowers. Meet Bjorn who will also be at the Gallows Tree.
During the cutscene, Bjorn burns his white bear (Njal) after his bear died.
He will then agree to join Eivor’s Raven Clan. The quest ends here.
