50k TNT Duping Obsidian Farm

An intermediate TNT duping forced nether portal obsidian farm. This cartless, unload proof design achieves high rates for a two-portal setup while keeping resource loss to a minimum.

How it works

• Uses two withers positioned inside the nether portal to break 14 obsidian every 20gt.
• Sends TNT through a portal to generate a forced portal and damage two withers.
• The wither cage uses the fact that the wither does not have direct line of sight with the chicken, so it does not shoot blue skulls. Upon reload, the chicken and the wither briefly have line of sight so the chicken becomes the wither's main target, before line of sight is blocked.
• The TNT is timed in such a way so that the portal frame will only be generated for 1gt before breaking. This ensures no items go to the nether and no items go flying around.

What it produces

• Obsidian: 50.4k/h

How to use it

• Find a suitable location in the Overworld over an ocean and ideally with minimal caves and land nearby. Go to that location in the Nether and build the Nether side of the farm.
• Do not rotate the schematic. TNT must come out of the portal in a certain direction.
• Toggle the Nether side briefly to generate a forced portal. If you spawn underground in caves, portal proof the 3x3 chunk area by flooding the cave or ensuring there are no groups of 4 flat blocks in a row. Then go back to the nether side of the farm.
• Once a forced portal has been generated above sea level, align the obsidian blocks in the schematic with the top row of the forced portal that generated. The Glass in the schematic should be on top of the obsidian. Build the overworld side.
• Briefly turn on the nether side to finish the farm.
• Head to the nether side of the farm and turn on the lever to start the farm.
• Keep the farm loaded with a chunkloader or an AFK player.
