A quick way to obtain the achievement "Rolling Required Ahead", using Save Editors
 

The "intended” Way

The "intended method" to obtain this achievement is at 3rd Beacon after the Twin Swords Mini-Boss mission. You'll find 10 barrels nearby that can easily be broken in just 15 seconds. However, the game on PC may not count the barrels correctly and it can take as long as half an hours.
 
 
Instead, there's another …. way.
 
 
 

The "other way".

You can save editing much, much faster than much
 
 
You need to do this at least on Windows.
 
 

• Close Thymesia.
• Navigate to save file, located at C:\\Users\USERNAMEHERE\AppData\Local\PlagueProject\Saved\SaveGames\random-string-of-number\Playersave1.sav
• USERNAME HERE is your Windows account name, random-string-of-numbers is a folder name and I'm not sure if it changes for different people.
• Then, copy the save file to this site.

• CTRL+F "NumBarrelsBreaked". Next, Double Click the number following it and change it back to 999.
• Save the file, and replace your original file in the folder by this modified file.
• Open Thymesia. After that, break some barrels.

 
 
I hope that this helps you!
