Instructions
Build
-
Find a location you want to build at and load either schematic
-
There should be NO lit portal within a 128x128 area from this platform, for all Y values in the overworld.
-
The wither and the boats should be in the same chunk
-
The farm is not directional but these directions and calculator assume that the Iron Golem is on the westmost side, which is default for the schematic. The TNT should also launch to the East.
-
Use this calculator and input either your nether or overworld coordinates to find the leftmost purple portal block location while facing east or the northern most inner portal block.
-
Build the overworld side water collection, but DO NOT build the wither cages and summon the withers yet.
-
Do not forget the signs on the sides of the obsidian in the schematic.
-
Finish building the farm
-
Summon all other mobs before the withers.
-
Refer to
for summoning the withers, starting the farm, and stopping the farm. The netherside must be chunkloaded.
-
Remove the water as shown in the video in
Usage
-
Use the lever in Nether side toggle the farm.
-
To keep it running, you either need to AFK at the Nether side or build a chunk loader to entity load the duper and TNTs.
-
You can do this easily by building the netherside of the chunkloader about 16 blocks from the farm's nether portal. This will generate a new portal in the overworld you can build a chunkloader with.
