Step 1: Gather Your Resources

You'll need a substantial quantity of blocks. Cobblestone and wood are readily accessible and ideal choices for this project.

Step 2: Choosing the Perfect Location

The optimal location for a mob farm is high in the sky. Ground-level construction is less effective, as mobs will spawn around the player or in nearby caves. Building your farm above water further enhances its efficiency, as mobs cannot spawn on water.

Construct a platform approximately 100 blocks above a body of water. Add ladders for easy 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 this height later if needed. Place slabs on top of the hoppers.

Construct four 7-block long, 2-block wide bridges extending from the tower. Build 2-block high walls around the bridges. Place two water blocks at the end of each bridge to create a contained water flow.

Connect the water trenches to form a large square. Ensure the walls are 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 across the roof to prevent mobs from spawning on top of the farm. Once complete, wait for nightfall and observe your efficient mob farm in action.

Tips for a More Efficient Mob Farm

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

  • Nether Portal Connection: Connect a Nether portal for easier access. A water elevator is another convenient option.
  • Adjustable XP/Farming Mode: Use pistons and a lever to easily switch between 21-block (XP farming) and 22-block (auto-farming) modes.
  • Bed Placement: Beds increase mob spawn rates; place one nearby.
  • Preventing Spider Spawns: Spiders can clog the farm. Place carpets, skipping every other block, to prevent their spawning. carpets to prevent spiders spawning

This completes your Minecraft mob farm. Enjoy the rewards!
