We've made some important changes to how duel tournaments work.
The first change is to how wins are determined. If neither player has died at the end of the three minute period, the player who has done the most damage in a duel will proceed to the next round, unless both players have dealt equal damage. In this case, the winner will be chosen by the Duel Tournament judge.
We have also reduced the number of players needed for a registrar to initiate a duel tournament. This will make it easier for you to enter tournaments of various levels.
