In Assassin's Creed Valhalla you may find Roman Artifacts, which are one of the collectibles in the game. On this page of our guide you will learn where to find masks and how to get to them. This will make it easier for you to complete the Hamtunscire region.
You will find the mask on the northeast of the location, near the region border.
To get to the mask, you have to shoot down the load that hangs from the ceiling.
When it falls down, it will make a hole in the floor. You must jump into it and take the desired item.
You will find this mask in the southern part of the location, in Wistman's Wood.
To get to the mask, you have to destroy the planks lying on the well and then jump in.
At the bottom, you have to open a rubbled passage, and find a mask lying right behind it. It's in the corner to the left, you should notice it immediately if you enter.
You will find the third mask when going west from Runewuda Abbey.
Here, you will come across the ruins where enemies and wild boars lurk. You have to get rid of them and approach the wooden box with the mask on it.
