1. Duelists make a deal, define their dueling rules, wage certain amount of DP and post all that info in their Shadow Arena Topic.
2. Winner by the rules they both agreed takes all waged DPs from both players.
3. You or your opponent have/has to confirm that he played you, but if you have a clear screenshot of the result it will still suffice.
4. You cannot duel an opponent that has the same IP like you. If you do, you will be permanently banned from Requiem.
