Go to "Superstar Management", and select the superstar you want to build up. If he does not have a belt, give him one for now. Set the difficulty to Easy, and choose a One On One Extreme Rules match. Fight a weak superstar with your superstar, and defend the title. In the match, use grapples, strikes, weapons, and taunts. Use your finisher, and pin them. You should get approximately 14 to 20 points for a one to two minute match. Distribute the CAW points as desired. Then, select "Re-match", and repeat this until you get your wrestler built up.
