The Amulet Of Kvasir talisman can be found very early in the game and is useful throughout the game. Once you are able to explore Alfheim, you can get this talisman. It works like a standard Platinum dodge - when Kratos dodges an attack, you will slow down time and perform strong counter-attacks. In Alfheim, you will eventually reach an area called the Light Elf Sanctuary. Find the Realm Tear past the crank gate, and proceed past the bridge made of roots. At this vantage point, you can see the beach where you first started the area. From here, throw your axe to break the root nodes, making a tunnel appear. Drop down to reach a room with a wheel crank. Use it to solve the root puzzle (break all three with a single throw) to make the legendary chest appear with the Amulet Of Kvasir talisman inside.
