To build a mob farm in Minecraft, follow these general steps to create an efficient structure that spawns mobs and collects their drops automatically:
Materials Needed
- At least 25 stacks of solid blocks (e.g., cobblestone)
- Trapdoors (about 1 stack)
- Hoppers (4 or more)
- Chests (4 or more)
- Slabs (a few)
- Buckets of water (2)
- Optional: scaffolding for building, torches for temporary lighting
Step-by-Step Guide
1. Build the Collection System (Mob Grinder Base)
- Dig a 2x2 hole one block deep.
- Place four chests facing the same direction in the hole to form double chests.
- Place hoppers on top of the chests, all linked together to funnel mob drops into the chests.
- Cover the hoppers with slabs to prevent mobs from spawning on them
2. Build the Walls and Spawning Chamber
- Build walls around the collection system, about 22 blocks high, floating two blocks above the base.
- At the top, build 2x8 bridges extending from all four sides, enclosed by two-block-high walls.
- Construct a large dark room or multiple spawning platforms inside the walls where mobs can spawn. Use 3x3 platforms spaced vertically about 2 blocks apart.
- Place trapdoors on the edges of the platforms and flip them open to trick mobs into falling off the edges.
- Ensure the interior is completely dark (light level 0) to maximize mob spawning; use blocks that block light, such as tinted glass or solid blocks
3. Add Water Channels
- Place water at strategic points on the spawning platforms to push mobs off into the fall chute leading to the collection system.
- Use signs or trapdoors to hold water in place without blocking mob movement
4. Build the Fall Shaft
- Create a vertical drop of about 20 blocks or more beneath the spawning platforms so mobs fall and take damage.
- The fall should weaken or kill mobs so you can collect their drops easily or get XP by finishing them off
5. Construct an AFK Spot
- Build an AFK platform about 80 blocks above the farm to maximize spawn rates by making the farm the only dark spawning area within range.
- Waiting here allows mobs to spawn and fall into the trap automatically
6. Final Touches
- Remove any torches inside the spawning area when ready to activate the farm.
- Optionally, add multiple layers of spawning platforms to increase mob spawn rates.
- Customize the farm with features like campfires to kill mobs silently or specific designs to target certain mobs (e.g., spiders, creepers)
This design works in both Java and Bedrock editions and is effective for gathering mob drops and XP efficiently. For a visual guide and detailed build, tutorials on YouTube by creators like Wattles or others provide step-by-step videos that can help you build the farm quickly
