Game guardian lets you edit your attributes, club levels, friendship levels, magizoology, notes, books etc...
I started using it 2 months ago on a throwaway account, and shortly after used it on my main account, and have not been banned at all. Also used it on 2 of my friends accounts for them and they have also not been banned at all.
When using it, I tend to be more "realistic" with the numbers used. A lot of the tuturial videos for it tell you to put numbers like "999999999" for things, but I prefer to look at the
spreadsheet for the game and get exact values.
