If you need to know how to complete the Mastery achievements, here will be described an easy solution to check what cards you’re missing.
 
 

Progression File Location

First, you need your progression file named achievements_progression.json
 
 
You can find this file in the directory:
 
%userprofile%\AppData\LocalLow\Abrakam Entertainment SA\Roguebook\Saves\Steam_xxxxxx/
 
 
%userprofile% points to the current user’s profile folder:
 

• For Windows Vista/7/8/10, this points to C:\Users\<Your Username>\.
• For Windows 2000/XP, this points to C:\Documents and Settings\<Your Username>\.

When Steam_xxxxxx is a succession of random numbers.
