Apart from letting players explore and conquer England in the Dark Ages, Assassin’s Creed Valhalla also takes players to the mythical realms of Norse mythology. Asgard and Joutenheim are present in the game, and players can actually travel to the realms quite early.
To be able to travel to Asgard and Joutenheim you need to wait until Valka the Seer comes to your settlement. She comes to the settlement once your settlement reaches level 3. After she arrives, you need to build Valka’s hut with the help of supplies. Supplies can be found by raiding monasteries and from chests.
Once Valka’s hut is ready, you need to gather a few ingredients for her potion. These ingredients can be found just beside her house, near the waterfall. Bring back the ingredients to Valka and she will make a potion. You need to drink the potion and you will travel to Asgard. The recommended power level for Asgard is 90.
For the sake of avoiding spoilers, we will avoid going into too much detail about how to reach Jotunheim. But you need to complete the Asgard arc first, and at the end of it, you will have to travel to Jotunheim. However, for that, you need to get another potion from Valka.
For the next potion, you need to go to Cent, which is in the southwestern part of the map to gather the ingredients. The ingredients are located in the Cavern of Trials, a cave hidden inside a house in Cent. You can use your raven to get the exact location after reaching Cent, and once you are inside the cave, use Odin vision to gather the ingredients.
Once you have the ingredients, head back to Valka and she will make a new potion with which you can travel to Jotunheim. You can travel to Asgard anytime by drinking the first potion which will be on the table in Valka’s hut.
