Most of the mods, specifically graphic mods and some gear mods that alters the appearance are doing injections in your file through the gpi program - I forgot the actual name of the program but it is something like this, I may edit this later. Moving on to 'why' you shouldn't mod in DS3. Originally posted by Agios:First of all, before adding anything mod related, and you did the smart thing coming here to ask about it, I would highly suggest you simply DON'T DO IT!
