Minecraft wiki entry for Player_versus_Player, associated text: If you join the attacking party, you should equip enchanted weapons with high damage. It is also good to equip weapons of mass destruction such as TNT, end crystals, lava buckets, etc. You should do everything in your power to keep your nametag hidden if you don't want to be banned. Being banned means you are out of the server, and out of the war. You can no longer fight alongside your comrades.
