Trial Chambers Finder
Trial chambers are easy to miss: they generate entirely underground, with no surface entrance and nothing above ground to hint one is below you. Instead of caving blindly, paste your seed into ezseed's map and every trial chamber gets a marker with its exact coordinates. It works for both Java (1.21 through 26.2) and Bedrock, runs in your browser, and doesn't ask for a download or an account. Click a marker to grab the coordinates, then head there in your world and dig to the copper corridors. And if your current world has nothing close by, the built-in seed finder can search thousands of seeds for one with a trial chamber near spawn.
How to use it
- Open ezseed.net, pick your edition (Java or Bedrock) and version, and enter your world seed.
- In the LAYERS rail on the left, make sure the Trial Chamber marker is toggled on.
- Use find-nearest-structure to jump to the closest trial chamber and read its exact X/Z coordinates from the marker popup.
- In your world, travel to those coordinates and dig down — chambers generate underground with no surface entrance.
- Want a fresh start? Open the FINDER panel and search seeds for "trial chambers near spawn."
Good to know
Trial chambers are 1.21's big underground addition: sprawling copper-and-tuff complexes full of trial spawners that send waves of mobs and drop keys for the loot vaults. Bring an ominous bottle to trigger an ominous trial if you want the tougher waves and the better vault rewards. Because the whole structure sits below ground, exact coordinates matter more here than for a village you can spot from a hill — and that's exactly what the map gives you. ezseed computes structure placement from the seed the same way the game does, so markers land where chambers actually generate, on both Java and Bedrock. Every view is stored in the URL — seed, position, zoom, edition — so you can send a teammate a link that opens centered on the chamber you plan to raid together. The distance-measure tool helps you pick the one closest to your base, and if you're still seed shopping, the FINDER panel filters thousands of seeds down to ones with a chamber near spawn.
FAQ
How do I find trial chambers with my seed?
Enter your seed on ezseed.net with your edition and version set, then turn on the Trial Chamber layer. Markers appear at every chamber on the map; click one for exact coordinates, or use find-nearest-structure to jump straight to the closest chamber to any point.
Does the finder work on Bedrock?
Yes. ezseed marks trial chambers for both Java (1.21 through 26.2) and Bedrock (through 26.30). Java and Bedrock generate structures differently, so make sure the edition toggle matches the platform your world was created on before you trust the coordinates.
How do I reach a trial chamber once I have the coordinates?
Travel to the X/Z position on the surface, then dig down carefully — a staircase mine is safer than digging straight down. Chambers are large, so you'll usually break into a corridor or room before long. Watch for tuff and copper blocks: that's the shell of the structure.
Can I find a seed that has a trial chamber at spawn?
Yes — open the FINDER panel on the right and set "trial chambers near spawn" as a criterion. It searches thousands of seeds and lists the ones that match, so you can start a new world with a chamber a short walk from your first spawn point.
