Spawners
See Spawn mechanics for the complete light, habitat, distance, population and unloading rules.
Rare cobblestone rooms deep underground contain a cage with a miniature Floater. Most rooms open into caves; a small minority are completely buried. Search newly explored terrain: established chunks keep their original generation.
This second view shows a generated room reached at known coordinates for verification. Dungeon discovery rates still need ordinary exploration playtests.
Stay within 36 blocks. The cage needs darkness, a suitable floor and enough empty space nearby for a Floater to fit. It attempts a spawn every 10 seconds while active. Failed attempts wait for another cycle.
Each cage supports up to five living mobs that came from that cage. A neighbouring cage has its own five-mob allowance. Ordinary natural hostile population limits do not consume this allowance. Killing or normally despawning one of its mobs frees a slot, subject to the next eligible attempt.
Floaters produced by cages still behave like ordinary Floaters and drop one Floater Rock when defeated. Walking away does not turn them into permanent residents: normal unloading and despawning rules apply.
Place torches around the cage and its floor. Light level 8 or higher prevents new Floaters; holding a torch only brightens your view. Light does not remove creatures already present.
Breaking a cage destroys it without dropping a collectible spawner. There is no Survival crafting or collection recipe. Keep a discovered cage intact if you want to use it later.
These screenshots come from the September 19, 2026 Alpha playtest verification room. The fixture demonstrates operation and lighting; it is not a claim that the room shown was discovered through ordinary play.
