Instructions
Press and hold "Triangle" at any time during the fight. Your character glows as the Secret Technique meter fills.
Press "Square" to activate your secret technique when at least one section of the bar is filled. For your character's strongest Secret Technique, fill all three sections of the bar.
Press the button in the lower left hand corner of the screen repeatedly to increase the amount of damage the move causes. For example, a rapidly flashing "Square" icon means you must press the "Square" button rapidly. The button you must press varies based on the Secret Technique. After a few seconds of pressing the button, the Secret Technique is performed automatically.
