Tutorials/Enderman farming

The purpose of an enderman trap (popularly called Ender Ender) 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, 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.

Description
The farm is built in the End at least 128 blocks away from the main island, so the endermen can only spawn there. A platform is built for the endermen to fall onto from spawning pads built at least 43 blocks above the platform, with rings built upwards to prevent endermen falling onto an area that isn't the platform. On the 43rd block up vines are placed to break the fall, so the endermen take 19.5 hearts damage, leaving them on half a heart.

The spawning pads either have pressure plates on them, connected to sticky pistons with blocks attached, or a tripwire attached to normal pistons to push the endermen off the pads, down the drop and landing on the platform with only half a heart of health left, allowing for one hit kills by punching. A good way to start punching is to create a two-high ceiling and start staring at the endermen. EthosLab has a good farm in his survival world.

Using this farm it is possible to get to level 30 in minutes, provided enough spawning pads have been built. Make sure to have many chests nearby to store the massive amounts of Ender Pearls!

Poor Man's Enderman farm
This design was made Sethbling. It is easy to use.
 * Build a 3-block pillar then destroy the bottom 2.
 * Using the corner, create a 5x1x5. Place a lever in the middle.
 * Create a 3x1x3 plate above the plate. Place a hole in the middle of this plate.
 * Place redstone in the visible hole on the top of the farm and the other 8 blocks around the hole.
 * Line sticky pistons on the edges, not the corners, so it pulls and pushes the blocks on the original 5x1x5 plate.
 * Start farming. Look at Endermen. When you have enough, power the lever and count to 39. Then you can punch them to finish them off.
 * Grab your pearls!

The Mushroom Trap

 * Build a 3-high pillar, then place Ender-proof blocks all around at the 3rd level. The resulting "mushroom" shape will allow you to look at Endermen, preferably in The End, and be completely immune to them.
 * Once they teleport and are against the sides of your structure, use your favorite Looting sword to kill them and farm Ender Pearls.
