Finding and Repairing Ruined Mob Farms

Finding and Repairing Ruined Mob Farms

Ruined mob farms are scattered deep underground as rare hidden structures. Search beneath different biomes to find broken spawner rooms—the normal variant generates under most overworld biomes, while lush cave versions appear specifically under jungles and lush caves.

When you discover a ruin, you'll find loot inside chests and a non-functional spawner. Collect the rewards, then repair the broken parts to restore the farm into a working mob grinder. These structures are intentionally rare, so finding one is a genuine secret. If you use Cinch's Missing Blocks add-on alongside this mod, the ruins will include additional special blocks, expanding the variety of these underground discoveries.
