A new type of Monster Spawner has arrived, and unlike the original, it is not quite as simple this time! So, today, we explore the
Minecraft 1.21 Trial Spawner, including where they are found, how they work, and the possible loot they can leave on the ground.
Where to Find Trial Spawners

Trial Spawners generate within the newly added
Trial Chamber structure, which appear between layers -20 and -40 of the overworld. Players seeking this elusive dungeon will have the best luck mining and exploring caves between these levels.
Once a Trial Chamber has been located, Trial Spawners will quickly be found within its various challenge chambers.
Minecraft 1.21 Trial Spawner Explained

When a Trial Spawner has been spotted, note the blocks surrounding its base as they indicate the type of
mob that will soon spawn from within. We have listed all the possible combinations below:
- Baby Zombie: Cobblestone & Mossy Cobblestone
- Zombie: Mossy Cobblestone
- Husk: Chiseled Sandstone
- Spider: Stone With Cobweb
- Cave Spider: Stone With Cobweb & Podzol With Mushroom
- Silverfish: Stone Bricks
- Slime: Moss Block
- Skeleton: Bone Block
- Bogged: Bone Block & Podzol With Mushroom
- Stray: Packed ice
- Breeze: Chiseled Tuff
Additionally, the number of mobs within a Trial Spawner depends on the number of players nearby. We listed the exact numbers below:
Breeze Trial Spawner
- Maximum Mob Count: 1 + 0.5 Per Additional Player
- Total Mobs Spawned: 2 + 1 Per Additional Player
Trial Spawners
- Maximum Mob Count: 2 + 1 Per Additional Player
- Total Mobs Spawned: 6 + 2 Per Additional Player
Finally, when a Trial Spawner has spawned all possible mobs, it will release
loot before going inactive for thirty minutes’ time. After that, it can be challenged once again.
