Trial Chambers: Loot Routes & Spawner Tactics
Trial chambers are underground copper-and-tuff structures with trial spawners, vaults and the breeze boss. This guide covers the loot table and the fastest safe route.
How to find one
Trial chambers generate under any biome below Y = 40, one per ~34×34 chunk region. Fastest method: /locate structure trial_chambers or the Seed Map structure overlay.
Loot table (trial spawner + vaults)
| Item | Where |
|---|---|
| Wind charges, breeze rods | Breeze drops (final room) |
| Diamond gear (rare), enchanted books | Trial vaults (need keys) |
| Copper blocks, tuff blocks | Walls and floors |
| Potions (regeneration, strength) | Corridor chests |
| Trial keys | Trial spawners (kill the wave) |
Safe route tactics
- Clear the spawner first: each trial spawner waves 3–5 mobs; kill the wave to unlock the trial key, then open nearby vaults.
- Breeze fight: the breeze floats and shoots wind charges — stay mobile, block its charge with a shield, and it damages itself.
- Don’t trigger the “ominous” variant until you have full diamond gear — ominous trial spawners drop heavy armor but hit much harder.
- Bring a sponge: chambers have flooded rooms; a sponge clears a 4-block area instantly.
- Mark your exit: chambers have multiple floors — place torches or wool arrows at junctions to avoid loops.
Common questions
Why can’t I open the vault? Vaults need trial keys from clearing spawners, or ominous keys from ominous spawners. Regular picks won’t work.
Do chambers reset? Yes — spawners recharge after 30 minutes if the area is unloaded; you can farm the same chamber repeatedly.
