And its not just a normal arena either....
16 players enter the arena. They will be divided in pairs, so they can PVP each other in distinct arenas. So there will be 8 groups of contestants in 8 diferent arenas. Each victory would grant you 2 points, while loosing would grant you only 1. None of the players would die, instead of that, once they reach the mark of 10 or less HP, the match would be over, and both of the contestants would be teleported out, to a PZ. Then there should have the next round. Randomly, the groups would be rearranged and there would be another fight.
Once this is done, the 8 most scoring players would go for the next round. Again, they would be divided in pairs and enter the arena. The 4 most scoring players would be in the semi-finals. From those 4, another 2 groups battle.
And then we come down to the finalists. Here there would be 3 battles. The best of those 3 (the one who kills the other 2 times) would win.
