Minecraft wiki entry for Player_versus_Player, associated text: Redstone is a vital skill to learn. The ability to make unseen and creative traps allows for the killing of enemies whose diamond-plated armor might be otherwise unstoppable. For example, the first thing enemies would normally do is take out the water around the base and replace it with lava. If that happens, and you have a BUD to confirm that water is still there, TNT is supposed to be set off under a pile of sand, with water to block out the damage to the environment (be careful using it without water, you'll probably get more damage done than you bargained for) and torches to break the sand. Maybe even not add torches to suffocate the enemies, but the explosion will be reduced. Another use is emergency switches. Set your faction's spawn point in a 2×2 hallway. Put an emergency button to pull in the blocks under you with sticky pistons and the enemy will fall into lava. Note that this is guaranteed to waste the enemy's armor, not to kill them. Use a button, not a lever! If you are looking for a way to win, then you can lay siege. At night, the simple plan is to make a 3 or 4 block trench around their base. Pillar up about 2 blocks and start a platform that takes people to the fort of the enemy. USE COBBLESTONE because the people under siege might light TNT. It could destroy your bridge if it is made of dirt or wood. Once you have the platform, expand it so it covers the entire trench which will make it a death trap. Close the box up and watch the players fall into the trap! Or before you fold up the box, make a stairway to the door and remove the door. Close the box. Now you can lay siege with the help of monsters! They could still light the box up and defeat all the mobs, but by that time they might be too weak to resist that you could 1 hit them.
