A mob farm is a crucial addition to any thriving Minecraft world, ranking alongside farms and villager trading halls in importance. This guide provides a straightforward method for constructing your own efficient mob farm.

Step 1: Gathering Resources
This build requires a substantial number of blocks, so prepare to gather materials. Cobblestone and wood are readily available and ideal choices due to their abundance.
Step 2: Choosing a Location

Constructing your mob farm in the sky is optimal. Ground-level builds hinder mob spawning, as they'll appear around you or in caves. An elevated location ensures mobs spawn solely within your farm. Building over water further enhances efficiency, as mobs cannot spawn on water.
Build 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 21 blocks high (for XP farming) or 22 blocks high (for automatic farming) around the hoppers. Place slabs atop the hoppers.

Step 4: Building the Water Trenches

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 to contain the water flow.

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

Place torches or slabs on the roof to prevent mob spawning there. Once complete, wait for nightfall and watch the mobs fall into your collection system.
Improving Mob Farm Efficiency

While the basic farm is functional, several enhancements can boost its efficiency:
- Nether Portal: Connect a Nether portal for convenient access. A water elevator is another option.
- Pistons for Switching Modes: Use pistons and a lever to easily switch between XP and automatic farming modes (by adjusting the tower height).
- Beds for Increased Spawn Rates: Place a bed nearby to increase mob spawn rates.
- Carpets to Prevent Spiders:

Spiders can hinder efficiency. Place carpets, skipping every other block, to prevent spider spawning.
This concludes the guide on building a mob farm in Minecraft. Enjoy the rewards!
