PvP is a great part of Minecraft but many players find it too difficult to engage. I will give you some simple tips to stay alive. First of all, stay away from mobs. They will damage you and it is very pointless. Save your life for killing others. You are going to need a sword (stone or better) and a bow with at least one stack of arrows. And plenty of food. You can either hunt, wander or camp. Campers tend to put themselves in a corner or a good hiding spot and hit opponents with a bow. This is a good strategy but Hunters can pick them out and sneek up on them. Hunters are very good against all if they get a good position but a Wanderer tends to know the landscape and good fight spots and can sometimes kill Hunters. Pick a class depending on what you do best and do what they do to stay alive.
