Usage

• []Open the online editor linked above or clone the repo and open index.html in any web browser.[/]

  []Select a .sav file (or .yaml) if you have one.[/]

  []Enter your Steam or Epic ID - whichever one you license the game through.

  []These can be found on each platform's account setting website, or in the save file path for Steam.[/]

  []Steam: https://store.steampowered.com/account/ (17 characters)[/]

  []Epic: https://www.epicgames.com/account/personal/ (32 characters)[/]

[]Click Import - This will decrypt the save and place the YAML text in the integrated editor.[/]

[]Export your original save as a backup. Keep these timestamped files in case something goes wrong.[/]

[]Edit your save as desired - refer to docs for basic info about the structure

• []Apply presets to automatically make common changes that are relatively safe & reliable. These are applied immediately when clicked.[/]

  []Switch the presets panel to Remove to undo supported presets. The panel is outlined in red while remove mode is on. Hover a preset for details.[/]

  []The YAML editor is shown by default. Click Hide YAML in the toolbar to give the presets the full width.[/]

[]Download as .sav[/]

[]Rename or delete your original save and replace it with the new one, removing the timestamp.

• []Recommended to keep a copy of the new save with the timestamp as a backup (in addition to the pre-edit backup).[/]

Notes:

• []Consider disabling cloud backups for the game to prevent save files from being reverted in some situations.[/]

  []You can safely replace saves while the game is running as long as a different character is selected.[/]

  []Modifying a save for a loaded character wont work as the save is in memory at that point and will overwrite the file on disk.[/]

  []Don't attempt to modify profile.sav while the game is running for the above reason.[/]
