Step 1: Gathering Resources

You'll need a substantial quantity of blocks, so prepare to gather materials. Cobblestone and wood are readily available and ideal choices for this project.

Step 2: Choosing a Location

The optimal location for a mob farm is elevated. Ground-level construction hinders spawning, as mobs will appear around the player or in nearby caves. Building your farm in the sky ensures mobs spawn solely within the designated area. Constructing it above a body of water further enhances efficiency, as mobs cannot spawn on water.

Build a platform approximately 100 blocks above a body of water. Add ladders for convenient access. Place a chest and connect four hoppers to it, as shown in the image.

Step 3: Constructing the Main Tower

Build a tower around the hoppers, extending it 21 blocks high for XP farming or 22 blocks for an automated farm. You can adjust the height later if needed. Place slabs atop the hoppers.

Construct 7-block long, 2-block wide bridges on all four sides, topped with 2-block high walls. Place two water blocks at each bridge's end. The water should stop at the bridge's edge, near the tower opening.

Step 5: Completing the Structure

Connect the water trenches to form a large square. The walls should be at least two blocks high to prevent mob spawning outside the designated area. Now, fill in the structure, completing the walls, floor, and roof.

Step 6: Adding Torches and Slabs

This final step is crucial. Place torches or slabs on the roof to prevent mob spawning there. Once complete, wait until night and observe the mobs falling into the collection system.

Tips for a More Efficient Mob Farm

While the basic farm is functional, several improvements can boost efficiency:

  • Nether Portal: Connect a Nether portal for easier access. A water elevator is another efficient alternative.
  • Pistons for Switching Modes: Use pistons and a lever to easily switch between XP farming (21 blocks high) and automated farming (22 blocks high).
  • Beds for Increased Spawn Rates: Place a bed nearby to boost spawn rates.
  • Carpets to Prevent Spiders:

Spiders can hinder efficiency. Place carpets, skipping a block between each, to prevent spider spawning. Spiders spawn on two blocks, while other mobs spawn on one.

This concludes the guide on building a mob farm in Minecraft.

Minecraft is available now on PlayStation, Xbox, Nintendo Switch, PC, and mobile.
