Before you can perform this trick you must have access to the town of Arniun. Start at Nam Cobanda Island and talk to the Kowz behind the desk with all the tables around to trigger a scene. Rita will want to take a test to get the Doctoral Degree. To take the test she must first find five books:
1. At Halure in the Mayor's House. Look at the book shelf.
2. At Capua Torim in Fortune's Market HQ. Look at the bookshelf.
3. At Heliord in the Investigation Room. Look on the left side of the room.
4. At Mantanic in the Inn. Look at the bookshelf.
5. At Aurnin in Aurniun's HQ. Look at Flynn's dresser.
When you have ALL the books go back to the Kowz and take the test where you will be quizzed on past Tales series of games. You will get the whether you pass or fail.
Play the sub-event when you have access to Nam Cobanda Island for Yuri, Rita, Estellise, and Karol to gain a costume title. The sub-event starts when you walk to the stage in the gymnasium and talk to the man standing there. Watch the funny scene and you will get the titles at the end.
Complete the game and save it to create a file marked with a star icon. When you load your saved file the 'EX New Game' option will appear. In 'Ex New Game' the Grade Shop is immediately available and you can purchase 'Battle Rank' for 50 Grade points for an additional difficulty setting. You will also have access to Nam Cobanda Isle at northwest part of the world map.
