SoloOne

🤔 Why is it needed?
Slay the Spire 2's multiplayer mode features different balances, mechanics, and separate leaderboards. Previously, this content could not be experienced without a second player. SoloOne removes this limitation.

⚠️ Tips about mod conflicts
**Multiplayer crashes when using mods? **
This is usually due to a mod mismatch. The solution? All users only need to install ModSync.
**Note:** Even with ModSync installed, mods that add cards, relics, or characters may still cause desynchronization during gameplay. For stable multiplayer, all players must have the exact same content mod. ModSync is best suited for UI, appearance, and gameplay tweaks that don't modify game data.

Install & use Install: follow the bundled instructions
- Unzip the archive from playbuff and read the bundled readme / instructions first.
- There is no universal mod manager for this game: some mods replace game files directly, some go into a game-specific Mods folder, and some need a game-specific community loader or tool first — follow the bundled readme.
- Place the files exactly as the readme says; mods with listed dependencies need those installed too.
- Launch the game to confirm it loaded; some games require enabling mods in settings or an in-game mod menu.
Install locations vary a lot between games and mods — the bundled readme is the most reliable guide.
