# Update 1.21 without trial chambers

Enables the Update 1.21 experimental features, but disables the trial chambers and breeze. Notably, in 1.20.5+ the new raid mechanics will also be enabled, with pillagers dropping ominous bottles instead of giving bad omen.

3. Enable the "Update 1.21" feature flag `level.dat`. A simple way to do this is by installing the [NBT Viewer](https://marketplace.visualstudio.com/items?itemName=Misodee.vscode-nbt) extension for [VSCode](https://code.visualstudio.com/)  

![](https://raw.githubusercontent.com/misode/no-trial-chambers/main/images/nbt_viewer_install.png)

4. Open the `level.dat` file in VSCode by dragging the file from the file explorer to the VSCode window

5. Inside `Data`, add a new list tag called `enabled_features`  

![](https://raw.githubusercontent.com/misode/no-trial-chambers/main/images/nbt_enabled_features.png)

6. Inside this list, add two new string tags with `minecraft:vanilla` and `minecraft:update_1_21`. Select the yellow string icon when adding the first tag.

7. Press `Ctrl + S` to save the file, make sure the world is not open in-game when editing the file!

8. In the world save folder, find the `datapacks` folder and put the downloaded zip file in there

9. You can now open the world!

Adding to a new multiplayer server

1. Download the server jar from the bottom of the [1.20.4 article](https://www.minecraft.net/en-us/article/minecraft-java-edition-1-20-4)

2. Place the `server.jar` file in the server folder

3. Inside this same folder, create the folders `world/datapacks/`

4. Put the downloaded zip file in there

5. Run the server jar for the first time

```sh

java -Xmx1024M -Xms1024M -jar server.jar nogui

```

6. Agree to the EULA by editing `eula.txt`

7. Run the server jar again. You should see `Found new data pack file/update_1_21_no_trial_chambers_1.20.4.zip, loading it automatically` in the log.

Adding to an existing multiplayer server

2. Modify the `world/level.dat` file following the same instructions from "Adding to an existing singleplayer world"

3. Add the downloaded zip file to the `world/datapacks/` folder

4. Restart the server
