The Duellist's cap is a hat that keeps track of the amount of kills in the Duel Arena of the wearer. The tier 3 cap shows that the player has won 100-499 duels. If a player gets 500 Duel Arena kills, they can turn it into a tier 4 cap by clicking Change-look. Together with the Wildstalker helmet, this cap will give the owner the ability to transform into a statue, which shows various PvP stats.
