You may battle the same opponent multiple times and take your revenge until you win. Here are a few things to keep in mind:
- You must take your revenge within the first 24 hours of the battle.
- Each Viking is limited to 10 revenge within the last 30 battles.
- You will not be able to revenge another viking's revenge.
- You will not be able to revenge if you already had a revenge against the opponent.
- Your opponent might have bought protection and cannot be revenged.
