Trial Chambers in Minecraft 1.21: All You Need to Know

Every new major update is exciting for the Minecraft community. The Minecraft Live 2023 event was streamed recently and, as expected, it revealed a whole bunch of new features coming to the game with the Minecraft 1.21 update. It’s not an End update nor is it an inventory update, it’s an update about combat and tinkering, with one of the most prominent additions being the Trial Chambers. Today, we will be exploring the trial chamber, a new combat-oriented structure, soon coming to Minecraft. So, get your armor and swords ready, and let’s jump in!

What Is a Trial Chamber in Minecraft

The trial chamber is an underground structure that varies in size and challenges. It focuses on providing players with unique and exciting combat challenges. Moreover, the visual style of this structure is nothing like you have seen before in the game. The trial chamber consists of procedurally generated rooms connected to the tunnels, staircases, and the central corridor. Though, those passageways may sometimes lead off to dead ends, similar to strongholds.

The corridor is a wide tunnel in the center of the structure, and it will lead to various rooms on multiple Y levels. The thick pillars all around this pathway will easily indicate this location. The chamber is filled with traps, dangers, supply, and treasure chests. Furthermore, you will notice that many of the blocks used in the structure are completely new.

All the Blocks Found in Trial Chambers

Besides already-known blocks like copper blocks and chains, there are also new Minecraft 1.21 tuff and copper block variants. Feel free to follow the linked article where all these blocks are showcased. Those include the following:

• Chiseled Copper
• Copper Grate
• Copper Door
• Copper Trapdoor
• Copper Bulb
• Tuff Slab
• Tuff Stairs
• Tuff Wall
• Chiseled Tuff
• Polished Tuff
• Polished Tuff Slab
• Polished Tuff Stairs
• Polished Tuff Wall
• Tuff Bricks
• Tuff Brick Slab
• Tuff Brick Stairs
• Tuff Brick Wall
• Chiseled Tuff Bricks

The copper block variants can exist in all four oxidation stages, giving you plenty more building and creative opportunities. Instead of torches or lanterns, trial chambers use a new light source called Copper Bulbs. They are special light source blocks that emit light based on the oxidation state they are at. If the bulb is fully oxidized, it will emit the lowest light level.

Whereas, if it’s at the initial stage and completely orange, it will emit the highest light level of 15. Similarly to other copper blocks, you can scrape off the oxidation with an axe and revert the copper bulb one stage back. You are also able to wax this block to preserve its state and light level. Moreover, this special lamp can only be turned on and off once they receive the redstone signal.

Meaning, if you’d like to turn off the copper bulb, it’s not enough to just deactivate the power source it’s attached to. But, you will need to activate it again to provide power to the bulb, turning it off. Feel free to check out our guide on how to make a copper bulb, where we go over it in detail.

Where Can You Find a Trial Chamber

Trial chambers are relatively common and generate in the deepslate layers of the Overworld dimension. Unlike ancient cities, they don’t generate too deep underground and some of the structure’s parts may even be found in the stone layers. So, you’ll most often find them by exploring caves at these levels.

Mobs in the Minecraft 1.21 Trial Chamber

The trial chamber is a structure geared towards combat experience and challenges. Therefore, mobs are one of the biggest and most important aspects of it. Two major mob features of this structure include the trial spawner and the Breeze.

1. Trial Spawner

Trial spawner is a special spawner type found only in the trial chambers. It spawns hostile mobs just like the regular mob spawner, but it also adapts to the number of players that join the battle. More players means a more difficult fight. Furthermore, this spawner will spawn mobs from three categories: melee, small melee, and ranged.

Each of these categories is guaranteed to spawn in the structure. Also, every trial chamber will only spawn one mob per category throughout the entire building. Luckily, the trial spawner itself will give you a hint about what mobs it will spawn based on the blocks surrounding it. Here are all the mobs that the trial spawner can spawn and the blocks associated with them:

• Melee
  • Zombie (mossy cobblestone)
  • Husk (chiseled sandstone)
  • Slime (moss block)
• Small Melee
  • Silverfish (stone bricks)
  • Baby Zombie (cobblestone and mossy cobblestone)
  • Spider (stone and cobweb on top)
  • Cave Spider (stone and cobweb on top and podzol with a red mushroom)
• Ranged
  • Stray (packed ice)
  • Skeleton (bone block)
  • Skeleton with Poison Tipped Arrow (bone block and podzol with a red mushroom)
• Breeze (chiseled tuff)

Trial spawner can spawn mobs regardless of the light level. Not only that, but those mobs stay persistent. This means they will not naturally despawn if you go far away. So, to get rid of them, you need to fight and defeat them.

Moreover, this spawner spawns mobs in batches, not continuously. If you are playing in a single-player world, these spawners will usually spawn three mobs at a time. Once you defeat the spawned mobs, the trial spawner will go into a cooldown state for 30 minutes, which is indicated by the smoke particles coming out from the center. Not only that, but it’ll also drop loot for you, in the form of precious resources.

You can come back later to the spawner and have another round of battles all over again, thus, bringing replayability and a chance to earn more rewards. Trial spawner is meant to provide you and your friends with an amazing and fun combat challenge, so it’s not as efficient as the regular spawner.

It will take a lot of time to break this block, and you cannot obtain and move it to a different location. All in all, the trial spawner will be a fun challenge, no matter whether you play in the single-player world or with your friends.

2. The Breeze

There’s another challenge in the trial chambers located underground, and it’s a playful hostile mob called Breeze. The Breeze is a new mob that spawns in trial chambers from the trial spawners with chiseled tuff blocks around them. It is a unique wind-controlling mob that moves around constantly and jumps from one location to the other.

The Breeze has a special ranged attack called wind charge. Once this projectile hits an entity, it will deal a small amount of damage to it. After the collision, the wind charge will create a wind burst that knocks back entities by several blocks.

In addition, this special attack can even interact with certain blocks such as:

• Levers
• Buttons
• Bells
• Fence Gates
• Lit Candles (get extinguished)
• Non-Iron Doors and Trapdoors

This makes the Breeze harder to deal with since some rooms in the trial chambers contain trapdoor trap areas on the floor, where players can get stuck.

Loot Found in Minecraft 1.21’s Trial Chambers

You can find loot in plenty of different locations throughout the trial chambers. There are supply chests, reward chests, barrels, dispensers, and even filled decorated pots. Here are the loot options you can find in each of the chest types:

• Entrance Chest

• Corridor Chest

• Intersection Chest

• Reward Chest

• Supply Chest

• Barrel

• Decorated Pot

• Dispenser

• Trial Spawner (consumables)

• Trial Spawner (key)

There you have it, folks. Now you know everything about trial chambers in Minecraft 1.21. Development is still in progress, so we may see some changes to generation or loot.
