I can only give directions on cheating if you are playing on PC, not sure how people go about it if they are on mobile.
If you play on Steam:
Download the CoG save game editor (Save manager and editor for Steam (open-source))
Follow the instructions in the forum thread. It can be a little finicky figuring out where to point the save game editor, but a little trial and error will see you through.
If you play on the CoG website:
Cheating when you play direct through the web is much easier.
Open the game
Press CTRL+SHFT+I
Go to the “Console” that opens
type stats.(the stat you want to change)=(the number you want to change it to)
Be careful of putting them to the absolute max. If an author hasn’t used fair math then having your stats at maximum when the game tries to add to them can break the game and throw an error. You also cannot do this on the stats menu, and you have to press the next button before the stats changes take effect.
If you make the decision to edit your stats please don’t bother authors if your game bugs out because of it. Mod at your own risk.
