Minecraft Trial Chamber Finder

How to find a trial chamber from a Minecraft seed

Where trial chambers generate

Trial chambers generate underground in almost any biome as large sprawling complexes of copper and tuff. They are the headline structure of Minecraft 1.21, and the scan coordinates drop you at the entrance rather than wandering the surface hoping the terrain reveals one.

Trial spawners and vaults

Trial spawners summon waves of mobs that match the room, and when cleared they drop loot keys. Vaults open with those keys for trial-chamber loot; ominous variants summon tougher mobs and drop heavier rewards. Bring gear and food for several rooms at once.

The mace heavy core

A heavy core from an ominous vault plus breeze rods and the breeze's wind charges lets you craft the mace, the new weapon that smashes mobs when you fall on them. Trial chambers are also the source of the trial key and its vault-exclusive loot table.

The scan runs in your browser on the same free engine as the main SeedFinder console: no download, no login, and it reads Bedrock and Java seeds. Prefer to script it? Use the same engine over the REST API. See the API documentation.
