Here you can duel other players. You can stake items/cash with other players at the Duel Arena, this is very risky as you can either gain or lose your riches.
While dueling players be sure to make sure that everything is the way it needs to be in the duel options before you accept the stake. Some players might alter a setting for there own advantage (ex.turning on the shield), therefore that player will have the advantage over you. So please be careful and remember this is at your own risk.
Please video all stakes, so if something happens that was not supposed to (bug abusing for example), you can make a report on the forums.
1) Type "::duel" in your chat box.
