There is an enemy in the game called Grow Apple (or Super Grow Apple). If you find one and have Arnaud leveled up enough with the move "Shut Out", use it immediately at the enemy HEX. This prevents the Apple from running away. If you have Yulie's "Quicken" ability, then use it on Arnaud as soon as possible so that he can use more abilities. Have Arnaud lower the Apple's speed with "Slow Down", and resistance and defense with "Fragile". If you have the "Extent" ability, then use it so the effects will not go away for another twenty turns. You must then use Yulie's "Quicken" ability to increase a HEX near the Apple so Jude can move to it. Also remember to use Jude's "Mystic" ability, and to use a Lucky Card on everyone to double experience. Finally, if you have enough time remaining and are leveled up enough, use Arnaud's "Hyper" ability on Jude to double his attack. Jude's HEX should now have WPN up and RFX up. The Apple's HEX should have RFX down, RES down, DEF down, and also Extent and Lock. Now, use Jude's Assault Buster (the most important attack you can use) to defeat the Apple. This will result in massive damage (sometimes about 300,000 and up, depending on your level). The Grow Apples give you an amount of experience equal to the damage you do to them minus 1. You also will get more experience if you gave Jude a few Growth Egg Badges, and Jude will get about 0.7 more experience for defeating the enemy. If you defeat a Super Grow Apple, the results are doubled (which can add up to over 2 million experience points). Note: This has the exact same effect with the Melchoms and Melchom Lichs to give you a large amount of Gella. These monsters can be found in three floor mini-dungeons around the game.

During your journey, you will sometimes encounter a creature named "Grow Apple". It's a level 1 enemy with 1 HP and has resistances on all attributes (fire, wind, water, earth). Kill him with a normal attack (non-magic) or else he will flee. If you kill him, he will give you an experience point equivalent to the amount of damage that you inflicted him. Note: The experience is doubled for the character used to kill him.

In Mim'krilu Skyway, you will encounter an enemy named "Flauros". It is a level 25 silver tiger-like creature that has an attribute "Soft". This means it is vulnerable to normal or physical attacks. Kill the other enemies, leaving Flauros alone. Then, surround him with your characters and hit him with normal attacks to give him a small amount of damage. Flauros will respond with a counterattack, but it will not do any damage to you. Instead, he will divide into two. Continuously hit him with normal attacks, killing one Flauros and repeat the process, making him divide into two. You can repeat this as many times as desired. Just make sure you do not kill them both. Note: For best results use Jude's Mystic with Lucky Card to gain more experience.

In Mim'krilu Skyway, after the save point, walk further until you see a big boulder of thick walls and two switches. The first is on the big floating brick and second is down next to it. Stomp on the second switch. You will see a wall that is blocking in some way rise up. Stomp on the first switch. The floating brick will move and it will bring you to an isolated place. Walk around to find some battles. If you encounter Flauros, four will appear instead of two. Note: There is a pink diamond in the middle of that isolated place. That crystal contains a very strong monster (level 90). If you find the key for the activation of that crystal, save the game first or you may lose your progress. The key is located two stages before the Boss fight with the Twin Dolls (Fior and Asia).

Finish the game at least once, and make a "Clear game" save. If you use this save to load the Ex. Files screen, it will have a different BGM (a bleeps-and-bloops synth version of the main theme.)
