Each week at 5am Sunday(EU server time), 20 (West Coast Time) and 16:00(East Coast Time) the top 16 guilds are randomly paired up for the first match.
The winner of each match goes into the top 8 and the losers into the bottom 8 in tournament fashion and the guilds are randomly paired up against each other. This repeats through 4 rounds, after which placings will be decided and the victor rewarded.
Rounds 1, 2, 3 and 4 are at 8pm server time on Monday, Wednesday, Friday and Saturday respectively.
Though stated in guild permissions, the Guild Master does not need to be present for the event and all participants may enter as soon as the event begins.
Up to 50 participants are selected by the Guild Master at any time, before or during the event. But no player may enter the battle without being selected.
