Do I need Experimental Gameplay turned on for this addon?

Yes. The Trial Spawner and several other blocks won't work without Experimental Gameplay enabled in your world settings. Make sure to turn it on before loading the packs.

What mobs does the Trial Spawner spawn?

It depends on what's placed around it. Moss nearby causes it to spawn slimes, while ice nearby causes it to spawn strays. Place one or the other to control which mob type appears.

How do I test the Trial Spawner at full 5-player strength by myself?

Place the Trial Spawner, then run the command /tag @s remove trial_spawner four times. That bumps it to max level so you can see the full loot drop without needing 4 other players.

Does the miniature Trial Chambers structure generate on its own?

Yes, it generates automatically in caves. You don't need to spawn it with a command, just explore underground and you should come across it.

Can I use this addon in an existing world?

Yes, you can apply it to an existing world through the world settings. Just make sure Experimental Gameplay is enabled and both packs are applied before loading in.

Trial Spawner Concept Addon for Minecraft PE/Bedrock 1.20

This addon brings the Trial Spawner and a bunch of blocks from Minecraft Live 2023 into Bedrock 1.20. It’s a concept build, so you get to try out how these blocks look and behave before they officially land in vanilla. A small miniature Trial Chambers structure also generates in caves, so there’s actually something to find and test.

Blocks Added

Copper Bulb, Exposed Copper Bulb, Weathered Copper Bulb, Oxidized Copper Bulb
Copper Vent
Copper Grate
Tuff Bricks
Chiseled Tuff Bricks
Polished Tuff
Trial Spawner

Block Details

Trial Spawner

The spawner scales to player count. With 1 player nearby it spawns fewer mobs, with 5 it goes full send. Clear all the mobs and it drops a prize. More players means more loot, specifically diamonds and emeralds.

After dropping loot it enters cooldown for a few minutes. Smoke rising from the top means it’s cooling down, come back later.
It only activates if there’s moss or ice placed around it. Moss triggers slimes, ice triggers strays.
More players nearby means it takes longer to start up.
To test it at max level (5 players), place the spawner then run this command 4 times: /tag @s remove trial_spawner

Copper Bulb

A light block that oxidizes over time, which cuts its light level. Scrape it with an axe to restore the brightness, or wax it with a honeycomb to stop oxidation. The miniature structure spawns these, so bring an axe when you go exploring.

Copper Grate

See-through and lets light pass through. Good for floors or ceilings where you want some visual depth without blocking light entirely.

Copper Vent

Purely decorative. No special function beyond filling out a copper-themed build.

Tuff Bricks

A polished stone block made from tuff. Generates inside the miniature Trial Chambers and works well for dungeon-style builds.

Chiseled Tuff Bricks

Same base as Tuff Bricks but with a carved pattern. Pairs well with plain Tuff Bricks for textured walls.

Polished Tuff

Smooth version of tuff. Rounds out the set nicely alongside the bricks and chiseled variant.
