You may challenge your friends or foes in a no-loot situation by saying
'' I wish to duel '' . Once both challengers accepted the rulesets, you will be sent to one of the 3 dueling areas. Once the duel is over, you will be sent outside which is still a safe zone unless you step out of the dueling pit area.
Say '' I yield '' to decline duels.
Dueling statistics are saved and shown on a Dueling Leaderboard which can be accessed at the dueling arenas.
