​
Server installation

Install Fabric Loader

If you haven’t already, install Fabric Loader on your server:
  1. Download the Fabric installer from fabricmc.net
  2. Run the installer and select your Minecraft version (1.21.11)
  3. Choose your server directory
Make sure you install Fabric Loader 0.18.4 or higher as earlier versions are not compatible.

Place the Soul Link Speedrun JAR file in your server’s mods folder.

Start your server

[Server thread/INFO] (Soul Link) Initializing Soul Link Speedrun
[Server thread/INFO] (Soul Link) Soul Link Speedrun initialized successfully!

​
Client installation

Players do not need to install this mod on their client! Soul Link Speedrun is entirely server-side.
Players can connect to your server with a vanilla Minecraft 1.21.11 client. The mod works seamlessly without requiring any client-side installation.

​

If you want to run Soul Link Speedrun in single-player:
1

Install Fabric Loader

Download and run the Fabric installer for Minecraft 1.21.11, selecting “Client” installation.

3

Launch Minecraft

Start Minecraft using the Fabric profile and create a new world or load an existing one.

​
Compatibility notes

​
Compatible with

  • Essentials: Only the server host needs to have it installed
  • Most Fabric mods: Generally compatible with other server-side mods
  • Modpacks: Feel free to include this mod in Modrinth/CurseForge modpacks without permission

​
Potential conflicts

Soul Link Speedrun may conflict with mods that modify:
  • Health and hunger mechanics
  • Portal behavior and world generation
  • Death handling and respawn logic
  • Player synchronization systems
If you experience issues with other mods, try running Soul Link Speedrun on a clean server with only Fabric API installed to isolate the problem.

​
Verify installation

To verify that Soul Link Speedrun is installed correctly:
  1. Join your server
  2. Run the /runinfo command
  3. You should see a message showing the current run state
If the command works, you’re ready to start your first speedrun!
