Minecraft wiki entry for Player_versus_Player, associated text: Dodge their attacks with your lightning reactions (or butter fingers) and stab by rapidly clicking your mouse's left click button (Tip: It is best to wait until the sword cools down until you hit again). If you have a shield, use your right mouse button to block attacks, sprint at opponents and hit whilst falling for critical hits (tip: If you are not touching the block under you, and you are in a cobweb, you count as falling, giving you critical hits! Then again, it is also hard to move when doing this, so keep that in mind)! If you practice, practice, and practice, nothing will stop you and a well equipped character!
