Important: Save File Information

Slay the Spire 2 keeps separate save files for modded and unmodded profiles.

This means your existing progress might not appear when you first launch the game with mods enabled.

Save locations:

Unmodded saves:

%APPDATA%\SlayTheSpire2\steam\<STEAM_ID>\1\profile1\saves

Modded saves:

%APPDATA%\SlayTheSpire2\steam\<STEAM_ID>\modded\profile1\saves

How to transfer your progress:

  1. Go to the unmodded saves folder.
  2. Copy your save file (progress.save).
  3. Paste it into the modded saves folder.

Make sure to copy the file instead of moving it, so you still have a backup of your original save.

Once copied, your progress will appear normally in the modded version of the game.
