Tutorials/Enderman farming

The purpose of an Enderman Trap is for the easy access and killing of endermen. It is possible for the user to create such a trap that can be used by simply standing still, and looking at the endermen. This angers any you look at, luring them into the trap. Most endermen traps are best suited to The End (To find the end portal click here), as endermen spawn at a considerably higher rate there. You can still create this trap in the normal world, but endermen spawn far less often.

'EATT' Design
The schematics of this EATT (Enderman Automated Termination Trap) are as follows:


 * Level the surrounding land and dig a 3x3x3 pit in the ground.
 * In the center of the pit, build a tower (at least 4 blocks high.)
 * Place 3 pistons on opposing sides of the pit.
 * Place 1 piston on each of the other opposing sides.
 * Conduct a test of the pistons.
 * Rig a lever behind a piston with one block in between(at the farthest extent of your reach)and place redstone in a ring around the pistons.
 * When the redstone, lever and pistons are correctly placed the pistons should extend and fill every space except the center and create an enclosed 2 block high space.

Using and Operating The Trap
To use the trap, stand on the pillar, grab a sword and look at an enderman. It will rush towards you and fall into the pit. Activate the lever and the pistons will extend. Wait a few moments and deactivate the lever. The enderman should be weakened by having its head smashed and you can kill it with one strike. An upgrade is placing pressure plates (wooden for testing, so you can activate the trap with an item, and stone for the enderman) at the bottom of the pit and rigging redstone into an AND Gate. The lever primes the trap and the enderman touching the pressure plates activates the pistons.

Experience Gains
It is possible for the user to gain EXP from this trap, as the character hitting a mob once will register the mobs' death as a user-kill. This means that even with the pistons crushing the mobs down to half a heart, you can still give experience from the player hitting the mobs at their point of death. It is also possible to switch the levers and pressure pads with a button, these can be timed to crush the Endermen, then release when they reach the health points of half a heart, readying the Endermen for a one hit kill from the player.

Mindcrack Endermen Trap
According to the Mindcracker Kurtjmac (known for his FarLands or Bust videos) the Mindcrack server employs an alternate, more efficient trap.

Description
An area is made where Endermen can spawn in the End. However, there are pressure plates and pistons that are triggered almost immediately after the endermen spawn. The pistons push or pull blocks that cause the endermen to fall, landing on a long platform so far down that the endermen take an extremely high amount of fall damage, thus allowing the player to kill the endermen with a single punch with their fist (or in Kurt's case, a loaf of bread).
