The exported save file (named LegendaryJourneySave) is encoded in Base64 format.

You might need to experiment with the decoded string to find the correct values, but once done, it is possible to modify everything including

• Gold
• Ore
• Crystals (premium currency)
• Level of each skill (Strength, Intelligence, Dexterity, Agility)
• Number of Gold detection/Fast travel/Reset AP&P +1
• Level of each equipment (max 2000), not recommended to modify things like the Notebook

If you don't want to mess with your save, then try entering the codes "GreatStart" "HaveFun" "Perk1" "Perk2" "Perkx2" "FreeReset" (without quotes) for some small bonuses.

1. Open the file using a program called Notepad++ (Or Notepad, if you prefer).
2. Go to Plugins -> MIME Tools -> Base64 Decode in the menu bar (if you have it). Be sure to select the entire string before choosing this option.
3. If you do not have the plugin above, then copy the whole string from the opened file and paste it into a site called Base64decode, and let the site decode it.
4. You can now mess around the decoded string as you like.
5. Once done, you will need to encode the string back in Base64 format. This is simply done by using the Base64 Encode option in MIME Tools, or using Base64 Encode. Save your file.
6. You can then import your modified save into the game.

Important: Backup a copy of your original save first, in case you mess up.

If you freeze the green bar at 5 it constantly clicks for you (double * 1)
