How To Make a Mob Farm in Minecraft (Easy, Step-By-Step Mob Spawner)

Author: Adam Feb 22,2025

This guide provides a straightforward method for constructing a highly effective mob farm in Minecraft. A mob farm is a crucial element for any successful Minecraft world, comparable in importance to farms and villager trading posts.

Step 1: Gather Resources

You'll require a substantial quantity of building blocks. Cobblestone and wood are readily accessible and ideal choices.

Step 2: Choose a Location

Constructing your mob farm at a high altitude is paramount. Ground-level construction will result in mob spawns elsewhere. Building above a body of water further optimizes the farm's efficiency, as mobs won't spawn on water. Construct a platform approximately 100 blocks high above water. Install ladders for easy access. Finally, position a chest and connect four hoppers as illustrated.

Step 3: Construct the Central Tower

Build a 4x4 tower around the hoppers, extending it to 21 blocks for XP farming or 22 blocks for automatic item collection. Place slabs atop the hoppers.

Step 4: Create Water Channels

Construct 7-block long, 2-block wide bridges on each of the four sides, topped with 2-block high walls. Place two water blocks at the end of each bridge to create channels leading into the central tower.

Step 5: Complete the Structure

Connect the water channels to form a large square. Ensure walls are at least two blocks high to prevent mob spawning outside the designated area. Complete the structure by adding walls, floor, and roof.

Step 6: Add Lighting and Slabs

XP/Auto-Farming Toggle: Use pistons and a lever to easily switch between XP and automatic item collection modes (21 blocks for XP, 22 for auto-farming).

Increased Spawn Rates with Beds: Place a bed nearby to boost spawn rates.

Spider Prevention: Use carpets strategically (carpet, gap, carpet) to prevent spider spawns and maintain efficient mob drops.
