Welcome to the multiplayer PVP battle arena fight! Here you can choose to kill animals to boost yourself or if you dare, go up against a fire-breathing dragon once you are at a high enough level. Go after lower level players and avoid higher ones so you can have the strength to take them on when you're ready to FIGHT!!!
