- Download the latest version of Grimarillion
- Open the zipped Grimarillion_v[version number].7z file, inside you should see a folder called Grimarillion. If you see database/resources folders, you've gone too far into the folder, go back one level. Keep this open or extract this file somewhere
- Navigate to your .../Grim Dawn/Mods/ directory. For steam this should be something like:
C:\Program Files (x86)\Steam\steamapps\common\Grim Dawn
- Drag and drop the Grimarillion folder into your mod directory.
When you get in game, if you go to choose a mod, if you see grimarillion ~ world001.map, you're good to go. If you don't see that, something went wrong and you should not play the mod yet until you figure out what happened.
