- Easy Grade
Instead of manually spamming Tidal Wave with Rita, try the following method. It works almost as well, and you do not have to do anything. Include Rita, Raven, and Estelle in your party. The fourth member can be anyone with the 'Item Thrower' skill. Turn off all other Artes for them so they are only using 'Tidal Wave', 'Tempest', and 'Holy Rain', respectively. For the battle strategy, set whoever has 'Item Thrower' to defend, watch TP, and no over limit or fatal strikes. For Rita and Estelle, set them to target different enemies, full attack and Artes, Artes only, keep formation, no items, over limit level 1, and no fatal strikes. Do the same for Raven, except do not use any over limit for him. As for special equipment, equip Blue Dice on Raven and the character with 'Item Thrower'. Equip Rita and Estelle with Risky Rings. Before the battle, have everyone set the 'Minimum Damage' skill. Make sure you have items to restore TP, such as Orange Gel. Also, make sure the battle difficulty is set to hard or higher for the Grade multiplier. Go just outside of Zaphias, and link encounter either the plant or mushroom enemies so you have at least six enemies in battle to keep the over limit above level 1. Finally, turn on the battle strategy. It should last roughly twenty minutes, and at the end you will receive approximately 800 Grade, with no work on your part.

- Alternate costumes on Nam Cobanda Isle
When you gain access to Nam Cobanda Isle, play through the sub-event. Estellise, Karol, Rita, and Yuri will get a costume title. To begin the sub-event, walk to the stage in the gymnasium, and talk to the man standing there. Then, just watch the funny scene, and get the titles at the end.

- Getting Rita's Miska Scholar title on Nam Cobanda Isle
You must have access to the town of Arniun before you can do this. Begin at Nam Cobanda Isle by talking to the Kowz behind the desk with all the tables around it to trigger a scene. Rita will want to take a test to get the Doctoral Degree. The only way to take the test is for her to find five books:

At Capua Torim in Fortune's Market HQ	Look at the bookshelf.
At Mantanic in the Inn	Look at the bookshelf.
At Halure in the Mayor's House	Look at the book shelf.
At Heliord in the Investigation Room	Look on the left side of the room.
At Aurnin in Aurniun's HQ	Look at Flynn's dresser.

Once you have all the books, go back to the Kowz, and take the test. You will be quizzed on past Tales series of games. It does not matter if you pass or fail; you still get the title either way.

- Easy experience
In the Sands Of Korgoth, immediately after Mantiac, stock up on Holy Bottles and Dark Bottles. Then, go to the Oasis save point, which will automatically heal all health and TP. From there, go north, and run around with the Holy Bottle until night falls. Once it does, turn on the Dark Bottles. This will bring out all the monsters. The ones to look for are the little starfish-like monsters (fairly easy to spot). They run very fast towards you. Engage in battle with them. You will receive 800 experience points for each one defeated. You can easily catch between six to eight of them per night. Nights last for about three minutes, resulting in about 4,800 to 6,400 experience points every time night falls. This is an easy way to level up quickly early in the game.

- Completion bonuses
Successfully complete the game, and save when prompted to create a file marked with a star icon. The 'EX New Game' option will now appear. Begin a new game session in 'EX New Game' mode to have the Grade Shop immediately available. You can also purchase 'Battle Rank' for 50 Grade points for an additional difficulty. Additionally, load your cleared saved game file to gain access to Nam Cobanda Isle at the northwest part of the World Map.
