Just unzip the editor anywhere you like. It will automatically find your characters. You have to select which character you would like to change. It will let you change lots of things like level, difficulty, skills, combart arts, basically loads of stuff. It does work with the characters from the Ice & Blood but you should not be playing a character when you edit it, you can be at the main start screen of the game though. Good luck with it, I have found it really good.
