Trial Chambers/Structure

Overhead view of a typical trial chambers layout.

The starting room of the structure is corridor/end. This room connects to a chamber and a section of a corridor. At the end of the section of a corridor, an intersection links to another chamber and another section of an corridor is generated, but this time it ends on the atrium, which then leads to the entrance room.

The structure then branches out from some corridor/straight pieces.

Components

Entrances

The trial chambers generate an entrance chamber, which contains multiple levels and always generate a 3x3 doorway made out of oxidized variants of chiseled copper, cut copper and copper blocks. Behind it is a 3x3x1 gap, which is visible by breaking the doorway or via Spectator mode. A vault is found in a high place, alongside with multiple chests behind copper block and chiseled copper pedestals. Most entrance chambers generate a vegetation platform in the center.

Corridors, atriums and ends

An isometric view of a corridor.

The trial chambers feature two corridors (corridor/straight) connecting one of the corridors corridor/end, and another connects to corridor/atrium_1, which connects into corridor/entrance pieces. The corridors are divided by an intersection in different sides, making a L-shape.

Addons such as decorated pots, flower pots, candles, tripwire traps, dispensers, chandeliers, stairs, platforms, vaults and trial spawners may generate in the corridor/straight pieces. Trial spawners are either melee, small melee, or ranged mob spawners, but never spawn breeze spawners.

Some corridor/straight pieces have a copper door that can either lead to nothing (a stone wall), a chamber, or a hallway.

Chambers

Chambers are combat rooms, larger than encounters and can contain multiple trial spawners and vaults and at least one ominous vault. Multiple potential entrances can spawn in the chamber. Some can be sealed, but only one of these potential entrances can be connected to:

• Hallways.
• Intersections.
• Corridor ends.
• Some corridor/straight pieces.

Most rooms generates a base in which various addons including copper grate hanging platforms and obstacles, corner and side structures, dispenser traps and corridor pots.

Each potential entrance, including the sealed ones, generates a disposal consisting of a hopper placed above a barrel, allowing the player to sort their inventory.
