It's a tool for configuring all world spawners. It allows you to change almost all of the default settings for the way spawners work in Valheim. You can modify almost all of them, from their position and speed, to their health and attack.

All modifications are saved to the config files, which can be found in the "GameDirectory" folder. The config files are saved to the "config" folder in the download directory.

You can use this tool to create your own worlds. With the help of the in-game tutorial, you can create a basic world and join it to a world you've created.
