Valberry is one of the ingredients needed for character ascension in Genshin Impact.
It is needed for Noelle to ascend, among possibly other characters as well.
Here’s how you can find Valberry (location) in Genshin Impact.
How to find Valberry
Valberry is a local specialty of Mondstadt and you can find it in the wild or on the Stormbearer Mountains.
It may be easier to go to the Stormbearer Mountains. The location of Valberry is shown in the map below, marked by the player location (blue).
Stormbearer Mountains is north of Mondstadt.
You should see a couple of Valberries together. I found some near the tree on the said mountains.
