Going Deeper… Assassin's Creed Valhalla Quest

1. Collect the plants for Valka's next potion

Valka will ask you to collect the plants she needs to prepare another potion. In total you will need to collect 3 x St. John's Wort and 2 x Fireweed. You will find them all in Cent, north of the Dover Cliffs, inside a hidden cave - Cavern of Trials. The entrance to the cave is located inside the house. You will find a ladder there, which you can use to go down to the caves.

There are more plants in the caves than you need. You can collect the necessary amount after visiting a few early caves. You will find the first Fireweed in the first larger cave...

...and the next Fireweed in the passage to the next cave.

In the next cave you will find two St. John's Worts.

The last St. John's Wort is a bit further away. Return to the cave where you found the first fireweed, jump into the tunnel below...

...go forward, pass through a cave with a wooden beam and platform,...

...and you will eventually reach the place where the plant grows.

Below you will find a video showing the whole Cavern of Trials where you can see exactly where the plants are and how to reach them.

2. Bring the plants to Valka

Return to Valka in Ravensthorpe. Talk to her and she'll create another potion which will allow you to bring up another vision in which you can visit Jotunheim.

3. Try the new potion

Drink the blue potion that is on the table next to the potion you used to visit Asgard.

You will fall asleep and start another vision in which you will travel to Jotunheim. Your first quest in this realm will be the "Mistress of the Iron Wood" quest.

When you complete the last of the quests in Jotunheim - "The Price of Wisdom" and leave this realm, you will return to Valka's hut and tell her what happened there. This will end this quest and you will receive another one in which you will have to return to Asgard - "Bound to Fate".
