Monster Spawner: Quick Answer

Monster spawners generate in monster rooms (dungeons), mineshafts, strongholds, Nether fortresses, bastion remnants and woodland mansions. Monster rooms are the most common and can't be found with /locate, because they are a world feature rather than a structure. Enter your seed and coordinates above to get the nearest spawners for an XP or mob farm.

Most common: Monster rooms: zombie, skeleton or spider
Activation: Player within 16 blocks
Spawns: Up to 4 mobs every 10 to 40 seconds
Breaking it: Drops 15 to 43 XP, never the block

What Is a Monster Spawner?

A monster spawner is a cage-like block with a small spinning mob inside. Whenever a player is within 16 blocks, it tries to spawn 4 of that mob nearby, then waits between 10 and about 40 seconds before trying again. As it waits, the mob model inside spins faster.

Spawners can't be picked up in Survival, even with Silk Touch. Breaking one with a pickaxe only gives 15 to 43 experience. That's why most players leave them in place and build a mob farm around them instead.

Where Monster Spawners Generate

Location	Spawner mob
Monster rooms (dungeons)	Zombie (50%), skeleton (25%) or spider (25%)
Mineshafts	Cave spider, surrounded by cobwebs
Strongholds	Silverfish, in the End portal room
Nether fortresses	Blaze, usually two per fortress
Bastion remnants	Magma cube, under the bridge in treasure rooms
Woodland mansions	Spider, in a rare secret room

Monster Rooms (Dungeons)

Monster rooms are small cobblestone rooms with a mossy cobblestone floor, a spawner in the middle and up to 2 chests. Each chunk gets 14 attempts to place one, so they are common: up to 10 can generate between Y 0 and 320, and up to 4 between Y -58 and -1. They always connect to a cave, canyon, mineshaft or stronghold.

Because monster rooms are features rather than structures, the /locate command can't find them, and they still generate when structures are turned off. Their chests can hold bones, gunpowder, string, bread, redstone, name tags, horse armor, music discs and golden apples.

How to Find a Monster Spawner

Get your world seed with /seed, or from the world settings screen.
Enter the seed and your X and Z coordinates in the Spawner Finder above, and pick your edition and version.
Travel to the nearest result and dig or cave to its Y level.
Without a tool, explore caves and listen for groups of zombies, skeletons or spiders. Mossy cobblestone and cobwebs are good signs.

Disabling a Spawner or Building a Farm

Zombie, skeleton and spider spawners need darkness. A single torch on the spawner stops them across the whole spawn area.
Blaze and silverfish spawners need a light level of 12 or more to stop, for example a dense grid of torches around the spawner.
Magma cubes spawn at any light level, so block their spawning space with solid blocks instead.
For an XP farm, light the room except for the spawner area, then build a water channel that pushes mobs into a kill chamber.
A spawner stops spawning when 6 or more of its mobs are already crowded around it, so keep the drop chute clear.

Frequently Asked Questions

Can you pick up a monster spawner in Survival?

No. Monster spawners can't be obtained in Survival, not even with Silk Touch. Breaking one with a pickaxe drops 15 to 43 experience orbs, and breaking it with anything else drops nothing. You can only get spawners in Creative mode or with commands.

How do you stop a spawner from spawning mobs?

For zombie, skeleton and spider spawners, place a torch on or next to the spawner: they need darkness to spawn. Blaze and silverfish spawners need light level 12 or more around them. Magma cubes ignore light, so fill their spawning area with solid blocks, which works for any spawner type.

What is the best spawner for an XP farm?

Zombie and skeleton spawners from monster rooms are the easiest to turn into XP farms, since they are common and need little light control. Blaze spawners in Nether fortresses give blaze rods as well as XP. Use the Spawner Finder above to check which spawners are close to your base.

Why can't /locate find dungeons?

Monster rooms, also called dungeons, are generated as a world feature rather than a structure. The /locate structure command only searches structures, so it can't find them. They also still generate when the Generate Structures option is off. A seed finder is the easiest way to get their coordinates.
