Duplicate a save profile?

[Jeod]

I'm playing StS on my PC and on my Steam Deck, and until recently I had now issues. However since I started to play with the Infinite Spire mod, I found that some mod content doesn't work nicely with cloud sync. So, since I already unlocked everything there was to unlock, I wanted to make a separate profile for the Deck where I would have another run and another Void Shards stockpile.

Is there a way to make a save profile that's a copy of another profile? I was hoping to just copy a file in SlayTheSpire/saves but it seems that unlock data is stored elsewhere, or just all 3 profiles are stored in the same file. I would like to avoid farming the unlocks again or cheating them.

If you want exact copy of your own profile, make a copy of all files (except steam_autocloud) in your preferences folder and add "1_" (for second save slot) or "2_" (for third save slot) to all of them to look like this: "STSUnlocks" will become "1_STSUnlocks".

Otherwise you can skim thorugh previous threads for 100% savefile
