Difficulty: Hard
Estimated time per run: 30-50 min

Iron farms exploit villager spreading and golem spawning mechanics to generate 3-5 stacks of iron per hour without farming golem drops manually.

Overview

Iron farms exploit villager spreading and golem spawning mechanics to generate 3-5 stacks of iron per hour without farming golem drops manually.

Build spawning platform 6 blocks above village (iron golem spawn check)
Hopper collection below kill zone (melting drops also recovers iron automatically)

Capture 10 villagers in holding pen (separate bed per 2 villagers minimum)
Position beds 50 blocks away from holding pen
Villagers see beds and become willing to breed (gossip mechanics)
Add pushing mechanism (minecart or piston) to move golems to kill zone
Kill zone: fall damage (20+ blocks) or lava + suffocation
Add status display: hopper reading (shows active farm state)
Connect to base; farm produces 8-12 iron ingots per iron golem (~2-5 golems/hour)
Expand to 2-4 separate spawning platforms if demand exceeds supply
Villager restocking: add profession blocks to replace casualties
Monitor for stuck golems; clear with piston/water if flow is disrupted

Iron golems spawn every 30-300 seconds if 10+ villagers and no golem exists
Golem spawning checks a 16x12x16 area; platform must be inside check range
Lava melting drops is automatic for iron; no sorting needed (except armor/sword)
Beds are the key trigger for breeding; no beds = no golems
Golem farms need active villagers; replace breeding villagers every few hours of AFKing
Early iron farm yields 1-2 stacks/hour; late game optimized farms yield 10+ stacks/hour

Recommended infrastructure loadout: rails/boats, beds, workstations, name tags, hoppers, and a protected zombie setup for curing loops.

Most failures come from unprotected villager pathing and poorly isolated raid triggers.
