Great Explorer Achievement
Task: Explore every zone of Northgard
Method: The Raven clan is the best clan for achieving this task due to their scout specific lore upgrades. ‘Rangers’ (pictured below) increases scouting and exploration speed by 100%. Also scouts no longer consume food and cannot be hurt while exploring.
This will save you the hassle of having to heal your scouts manual as with other clans, as well as reduce the time taken to explore the map. You will need to upgrade your scout camp[northgard.wikia.com] in order to explore enemy territories.
