World download link and notes

World link, the farm is right underneath the spawn. Includes the fishing farm, if anyone needs: https://drive.google.com/file/d/1dFZ0sVFUEqjY7aEjoLXVnVz1t3JYs1JD/view?usp=sharing

The main idea is simple: you stand on the platform, activate the switch and the biome gets active, mobs start to spawn rapidly. With this setup you can farm every biome key without leaving the farm.

This farm could be most certainly improved further, but I lost interest after finishing the run. You're welcome to try and add more, like dungeon or whatever.

Notes, will be updated as needed:

• Crimson/Corruption and Hallow negate each other, this farm is built the way that they cancel each other JUST RIGHT. If you decide to build the version with Crimson and Corruption take 300 blocks to register a biome, while Hallow takes 125. If you build it without Hallow, fill the marked 75x4 spaces, remove innermost 45 blocks, use 42 for platforms and 3 as a biome border as shown.
  
• Activating ice biome and moving to Hallow, Crimson or Corruption recognition areas will allow for Pigrons to spawn, which can be farmed for one of the best food options: bacon.
  
• Activating dessert biome and moving to evil biome recognition areas will allow for dessert spirit spawns, which can be farmed for rare mage weapon ingredient.
  
• Regarding mimics: if you register one, you can either ignore it to despawn (as biome variants can be too dangerous in certain cases), provoke them with weapons if you can reach them, or quickly deactivate and activate the platform they rest upon so they fall into lava and get provoked.
  
• If skeleton merchant spawns, he interferes with mob spawning rates. I suggest quickly deactivating and reactivating the platform he stands on, as with mimics, so he drops and dies in lava.
  
• For marble/granite spawns, replace plain stone with the one you need, get back to grinder and place same marble/granite beneath your legs to boost their spawns.

[Archivist]

oh one of the images didn't work with my phone

[T-Machine]

I don't have enough time to edit a video about it, so no, I'm not planning on doing anytime soon. Elaborate on the wiring image being broken? Everything works just fine.
