In Assassin's Creed Valhalla Wrath of the Druids, you will come across Offering Altars. On this page, you will learn where to find these altars. This will help you to max out the Meath region.
The Offering Altar is in the southern part of the region.
You need 5 large sturgeons to complete this activity. You will find them in the river located north of the altar. You can fish them out or shoot with a bow.
