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

Author:Kristen Update:Feb 24,2025

Constructing a highly efficient mob farm in Minecraft is crucial for resource gathering and XP farming. This guide simplifies the process.

Step 1: Gather Resources

Begin by accumulating a substantial quantity of building blocks. Cobblestone and wood are readily accessible and ideal choices.

Step 2: Optimal Spawner Location

Construct your mob farm high above ground level, ideally over water. This prevents ground-level mob spawns and ensures mobs spawn solely within your farm. Build a small platform approximately 100 blocks high, adding ladders for easy access. A chest with four connected hoppers should be placed on this platform (as shown in the image).

Step 3: Constructing the Main Tower

Build a 4x4 tower around the hoppers, extending it 21 blocks high for XP farming or 22 blocks for automatic mob killing. Place slabs atop the hoppers.

Step 4: Creating Water Trenches

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

Step 5: Completing the Structure

Connect the water trenches to form a large square. Ensure walls are at least two blocks high to prevent mob spawning outside the designated area. Finally, fully enclose the structure with a roof and walls.

Step 6: Illumination and Slab Placement

Place torches or slabs across the roof to prevent mob spawning on top. This final step completes the basic mob farm.

  • Nether Portal Integration: Connect a Nether portal for convenient access.

  • XP/Auto-Farming Toggle: Use pistons and a lever to switch between 21-block (XP) and 22-block (auto-kill) configurations.

  • Bed Placement: A nearby bed significantly boosts mob spawn rates.

  • Spider Prevention: Place carpets with one block spacing to prevent spider spawns and maintain efficient mob drops.
