Trial Chambers Guide: Trial Keys, Vaults, Breezes and the Mace

Trial chambers came with the Tricky Trials update. They are big underground buildings made of copper and tuff, full of mob spawners, puzzles and loot. They are also the only place to get the mace.

Where to find them

• Trial chambers are underground, usually between Y -40 and 0.
• Look for copper and tuff bricks on cave walls.
• A journeyman cartographer villager sells a trial chambers map for emeralds and a compass.
• Exposed tunnels with strange square shapes in caves are often part of a trial chamber.

Trial spawners

Trial spawners activate when you get close. They spawn a set number of mobs based on how many players are nearby. Kill them all and the spawner drops loot and often a trial key. Then it goes to sleep for a while.

Light and blocks do not stop trial spawners. You have to fight.

Vaults and trial keys

Use a trial key on a vault to get loot like diamonds, enchanted books, emeralds and golden apples. Each player can open each vault once, so in multiplayer every player gets their own loot.

Breezes and wind charges

The breeze is a mob that only spawns here. It jumps around and shoots wind charges that knock you back. Kill it for breeze rods, which craft into wind charges. You can throw wind charges to launch yourself high into the air.

Ominous trials

Drink an ominous bottle (dropped by raid captains) before you go in. The spawners turn ominous: stronger mobs with better gear. Beat them for ominous trial keys, which open ominous vaults with better loot.

How to make the mace

Ominous vaults have a small chance to drop a heavy core. Craft the heavy core with a breeze rod to make the mace. The mace hits harder the farther you fall before you hit. Combine it with wind charges to launch up and smash down.

Tips

• Bring a shield, food, and blocks to wall off spawners you are not ready for.
• The chambers are a maze. Mark the way you came.
• Look for the Flow and Bolt armor trims in the vaults. See our armor trims guide.
