On this page of the Assassin's Creed Valhalla guide, you will find a walkthrough description of the duel with the boss Loki. You will learn when the confrontation with Loki begins, what attacks the boss has and how to avoid them, as well as how to defeat him effectively and quickly.
The duel with Loki takes place during the story mission The Price of Wisdom. Eivor (Havi) has obtained a sample of the Jotuns' magical honey and goes to Mimir's Well to finally get what he wants. Loki is waiting for him on the spot and challenges him to a duel.
Loki is a clever and cunning opponent who uses illusions while fighting to confuse his opponent. His likeness will appear all over the arena - when you hit them, they will vanish into thin air. This opponent also often uses offensive magic and can hurl magical projectiles at the enemy, which you need to avoid.
The god of trickery has an assortment of unblockable attacks, which are indicated by a red rune flash - you must avoid them, too.
Loki is not too resilient, so if you manage to hit him once, you'll have a chance to unleash a quick combination of punches that will heavily damage his health bar. Firing arrows from a bow is just as effective, especially when aiming at his head. Each projectile will do considerable damage.
Loki can also teleport behind his opponent's back and strike by surprise. As soon as you see the blue glow and Loki's outline, perform a dodge.
After the fight, you will not be able to kill the defeated opponent. Loki will turn into a fish and dive into the water, thus leaving the location.
