Lobby Duels
Maybe add a feature to allow players to have a duel in lobby (Can be started by command such as: /duel , this player will be prompted with a screen either to accept or decline the duel, once the duel is denied, they cannot receive another duel from the same player for a limited time). Other players will be able to watch as the duel goes on (optional; by choice.) If a player has second thoughts about the duel, they can back out of it using a command. (Example: /forfeit)
