About the Trial Chamber Finder
Trial chambers are underground copper and tuff vaults added in Minecraft 1.21, the Tricky Trials update. They hold trial spawners, vaults full of loot, the Breeze, and the heavy core you need for a mace. They’re buried deep, so you rarely stumble on one by accident. A trial chamber finder reads your seed and shows where to dig.
What you get on this page:
- Closest trial chambers first: the 12 nearest chambers to spawn or any X and Z
- Exact X and Z: dig down at the right spot
- Copy and go: a ready /tp command for each one
- Full seed map: see the chambers next to villages and other structures
How to Use the Trial Chamber Finder
Step 1: Enter Your Seed
Type /seed in Minecraft chat and paste the number.
Step 2: Pick a 1.21+ Version
Trial chambers exist in Java 1.21 and later. Pick the version that generated the area you’re exploring.
Step 3: Find Trial Chambers
Leave Search from blank to search around spawn, or type any X and Z, then press Find trial chambers. Each row shows coordinates, distance, and direction.
Step 4: Dig Down
Go to the X and Z and dig a staircase down. Most chambers sit between about Y -40 and Y -20. When you hit copper, tuff bricks, or oxidized walls, you’re in.
Where Trial Chambers Generate
| Fact | Value |
|---|---|
| Added in | 1.21 (Tricky Trials) |

What’s Inside a Trial Chamber
- Trial spawners that release waves of mobs, then reward you with loot
- Vaults you open with trial keys, and ominous vaults you open with ominous trial keys
- The Breeze, which drops breeze rods for the wind charge and the mace
- Heavy core, a rare vault drop needed to craft the mace
- Copper bulbs, copper grates, tuff, and decorated pots
- Enchanted books, emeralds, diamonds, and armor trims
Trial Chamber Locator Command
| Edition | Command |
|---|---|
| Java 1.21+ | /locate structure minecraft:trial_chambers |
| Bedrock | /locate structure trial_chambers |
You need cheats on. The finder gives you the same location from the seed without cheats.
Minecraft Java Trial Chamber Finder
This finder supports Java 1.21 up to the latest release, including the 26.x updates. Turn on Large Biomes if your world uses it.
Trial Chamber Finder Bedrock
Bedrock places structures with its own rules, so Java positions won’t match a Bedrock world. On Bedrock, use /locate structure trial_chambers with cheats, or look for exposed tuff and copper in caves.
How to Find a Trial Chamber Without a Finder
- Explore large caves and ravines. Chambers often cut into caves.
- Look for tuff bricks and copper blocks in cave walls.
- Trade with a cartographer villager in 1.21 for a trial explorer map, which points to the nearest chamber.
Tips for Your First Trial Chamber
- Bring a shield, a bow, and plenty of food. Breezes knock you around.
- Collect every trial key. Each one opens a vault once per player.
- Drink an ominous bottle before an ominous trial for better loot.
- Light the corridors so normal mobs don’t add to the trials.
Common Mistakes
- Picking a version before 1.21
- Using Java coordinates in a Bedrock world
- Digging straight down into a spawner room

Final Thoughts
