Want to fight with someone 1 on 1? Duels are the perfect feature for you.
Use /duel (Nick / ID) [bet] to challenge a player to a 1v1 Duel.
You can select how many rounds (up to 9) that you would like.
You can also select which arena you would like to have the duel in or just have the duel in different arenas for different rounds.
From there, you can select if you would rather use the default spawn weapons for the duel or certain weapons!
After that is selected and the person you challenged to a duel accepts, the duel begins!
