Blood, the art of war is just a group you join, there are 3
Bandit
Warrior
Monk
There were also servers for each class
It used to be that if you have the warrior AOW and you beat a Monk in the monk server they lose a flag, so this goes on with each AOW class trying to deplete the other classes flags. It was a failed plan imo, and now im sitting with a warrior AOW aswell, that I can do nothing with -_-
So just keep it because I doubt anyone will buy or trade it, because the AOW stuff is dead!
