Assassin's Creed Valhalla: 10 Secret Bosses You Must Find
10. Erik Loyalskull
To the north of the Fornburg waterfall you'll find a man by the name of Erik Loyalskull. As it turns out he's one of the 6 lost drengr of Ragnar Lothbrok, the first Viking to make a name for himself in England.
Talking to the drengr will have you learn that he feels a great amount of guilt for not dying alongside his King, and would like to make amends the Viking-way by fighting you to the death. It is only with a warriors-death that one can enter Valhalla, after all.
But before you say yes to this challenge keep in mind that although Fornburg has a power rating of 1, Erik Loyalskull is a seasoned drengr with a power level of around 50, so you might have some trouble taking him on immediately.
The key to this fight is staying mobile and wearing him down. Creating some distance will usually trigger a 5 hit throwing axe combo which can easily be blocked. If you aren't wielding a shield, get ready to dodge and take the opportunity to hit his vital points with your bow. When in close quarters avoid his heavy and runic attacks and parry his animated overhead attack.
Once sufficiently weakened it's all about the dodge and counterattack. Simply rinse and repeat until you've sent him to Valhalla.
