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 max out the Suthsexe region.
You will find the Suthsexe mask in Cicestre Abbey.
To get to the mask you have to slide down on a rope and drop down to the roof of one of the buildings. This is the only way to get to the top. The mask is on the roof, without any cover or protection.
The second mask in this location can be found at the very southern end of the area.
All you have to do is to destroy the rocks that are blocking the passageway and jump into the water. At the very bottom, the mask awaits you.
The mask in this location is hidden at the border, in the southwestern corner of the area.
All you have to do is to drop down on the roof of the building and pick up it. There is no other way to get to the location, you can't climb it or enter from below.
