A duel is a challenge between two players, wherein they battle it out. When a player challenges someone to a duel, the challenged player will receive a notification in the bottom right corner of their screen. They will have to press the E button to open the notification and will then have the option to accept or decline. Once a challenge has been made, a pole that holds two crossed swords will appear. If the duel has been accepted, duelists may not leave the area around the pole or that player will be disqualified.
(Note: You do NOT regain your health once a duel has ended)
