Enter the arena to fight against other players. Select one of three suggested opponents and accept the challenge in the popup window.
If you win you are rewarded with honor and gold. Moreover, you also get scrapbook stickers of your opponent's items if you don't already have them.
If you win you receive XP for the first ten wins of the day but only if you win a minimum of 100 honor and/or the opponent is up to 20 ranks lower than your character.
You can manually choose an opponent in the hall of fame but without getting XP.
You can save fights by ticking the box in the fight window. You can watch saved fights again in the fights tab of your PM box.
Hint: if the honor gap between you and your opponent is too high you won't win or lose anything.
Hint: the chance of getting the first strike is 50%. Both players start with their default damage but it increases each fight round.
