Vikings may face three difficulties (Easy, Medium, Hard) in our new Quest system. The harder it gets, the more Energy will be needed, but the better the rewards will be. Before you can face the more difficult battles, you must proof yourself in the easier tier.
You will have a limited amount of completions (victories) in each tier, indicated by the bar of squares at the bottom.
Every third completion will give you the chance to participate in a special challenge, which will give you extra rewards.
