Slay the Spire II UnifiedSavePath Mod v1.0.3

                    
Slay the Spire II normally routes your modded saves into a completely separate directory. Consequently, any progress you make while running mods never carries over to your main vanilla profile. The UnifiedSavePath mod fixes this annoying separation permanently. It merges both save paths into one single shared directory. Furthermore, all your unlocks, run history, and epoch progress stay together regardless of how you launch the game.
What’s Included

Unifies the save directory for both modded and vanilla play.
Shares character unlocks, epoch progress, and full run history across both modes.
Patches the internal UserDataPathProvider.IsRunningModded check to always return false.
Requires no external mod loader since it uses the game’s native mod loading system.
Compatible with all other mods without any conflicts.
Note: Any progress made with gameplay-altering mods will persist in your main save file.

Why You Need This Mod
Switching between modded and vanilla play normally splits your entire progression in two. This forces you to choose between enjoying mods and keeping a clean main save. However, this mod eliminates that frustrating trade-off entirely. Moreover, it modifies nothing about actual gameplay content. Therefore, it serves as an essential utility for any player who runs mods regularly alongside their main campaign.
How to Get Started

First, download the UnifiedSavePaths archive to your PC.
Next, extract the ZIP file into your game’s mods/ folder.
For example: Steam\steamapps\common\Slay the Spire 2\mods\
Confirm that both UnifiedSavePath.dll and UnifiedSavePath.pck appear in that folder.
Launch the game and click Yes when prompted to load mods.
To uninstall, simply remove both files from the mods folder.
