Minecraft wiki entry for Things_not_to_do, associated text: In a PvP (player vs player) battle, players normally take the best equipment to fight other players. Most use enchanted diamond armor or diamond swords. For PvP, the player should not use anything made out of leather, wood, or gold as armor and tools made of these materials are extremely weak. Some other less straightforward tools such as lava buckets and end crystals may also be used as weapons.
