Getting the Enternal Sphere  -  First get the Sharp Edge from Gamgee after the tournament of arms then use the customize speciality and combine it with mithril and then you'll get the minus sword, then combine another piece of mithril and you'll have the Enternal Sphere (it helps to have the orchestra playing while doing this) ^_^

Secret Shop  -  During the second disk after you get the Synard fly around the snowy islands and between the 2 large islands are 3 smaller ones land on the middle island and run around until the screen fades a way and you end up some where.

Go back to Expel  -  When you are about to meet the final boss save and head back out of the tower and go to fun city and talk to the old man in the battle arena and answer every question with "yes". WARNING: I haven't found a way back to Nede ^_^

Universal Difficulty Level  -  If you get over 45% of the voice clips, which is about 600 or so, a new 'Universal' difficulty level will open up. Enemy HP and Attack power is doubled in this mode.

Two Levels for the Price of One  -  You must have two items in your inventory for this to work: "Forged Medals" and the "Dream Bracelet." (I suggest reproducing medals until you have many). Equip the Dream Bracelet on the character you wish to level. Now use a Forged Medal on that character. De-equip the Dream Bracelet. After the next battle, you will gain two levels, at the cost of only one Forged Medal.

The Ring of Happiness  -  When you are told to go to the town of Cross for the first time,stop in Alen's house on your way through. Talk to him twice. The second time he should give you the "Ring of Happiness".

Rip Off Santa  -  Here is a simple cheat that will help you purchase those majorly overpriced Santa Boots 10,000,000 Fol) from Santa, the wandering merchant on the 6th floor of the Cave of Trials. First off, you have to meet him. Santa will appear randomly on Level 6, usually by the statues of the thieves so if he isn't there the first time, try leaving the dungeon and comming back. When you finally meet up with him, he will sell Sage's Stones for 50,000 Fol a piece and buy them back for 65,000 Fol. Buy 20 Sage's Stones and sell them right back to him for a 15,000 Fol profit!! Now, if you have the super specialty command Identify All, you can make a 45,000 Fol profit by buying low and selling high! I just wonder if I'll get that Eternal Sphere I wanted for Christmas?

Priest's Password  -  In the demon's den there is a glass priest who asks you for the special word necessary to get the cardkey. The password is APOCA.

Hidden Dungeon Tips  -  The Hidden dungeon is tough and interesting at the same time. There a various enemies here that have a word in front of their name that are very tough...however, there are weapons [normally useless] that have that same word that wil kill the enemy with one hit. Example:Lvl.99 Funny Thief...pretty tough, Lvl.99 Funny Thief when someone has the Funny Slayer...one hit kill. On the sixth level, there will be a man who occasionally appears in the statue room. He sells very rare stuff, including all the rare metals, the real tri-emblem [not the fake "emplem"], and items that can teleport you out of the dungeon....for you see, there are no save points, so if you are on level 13 of the dungeon and die, your screwed, so you must leave to save on occasion, and when you re-enter there will be methods of going down quickly, such as a trap door. The dungeon also contains very powerful equipment, including [but not limited to] The Levantine Sword, Ashton's ultimate attack, Leon's ultimate attack, Celine's ultimate attack, the angel armband, several pair of bunny shoes, and the valiant armor. As far as monsters go, from around level 3 onward, you may run into boss class monsters as normal fights...you can even run into the last boss of the dungeon as a normal
enemy, so be careful.

Hidden Dungeon  -  Save in front of the last boss, and leave the final dungeon. Proceed to fun city and talk to the old man in the back area of the colisseum. Say yes to all his questions, and you'll be transported back to expel, in Arlia. You'll notice two important things that are different: 1.There is a penguin walking around where you appear, talk to him and call him silly, he'll kick you back to Nede. 2. When you leave, there will be a Synard waiting for you. Hop on it and head to the area you couldn't access without it, the dungeon should be glowing with a red dot. Land and enter. The special dungeon is very tough, much harder than the regular last Dungeon...in fact, you'll start out fighting harder enemies than you saw in the normal last dungeon on the very first floor.

Easy Skill Level Gain  -  For an easy way to level up skills, you need to level up the perseverance skill to level 10. After you do this, leveling up the other skills will be much easier. For example making it where you can level up most skills with just one Skill Point.

Easy Money  -  When you get your Super Specialty Skill "Master Chef" up to level 6 or higher, go to a store that sells fruits, vegetables, and egg/dairy products. But 20 of each, then go to Super Specialty Skills and choose "Master Chef" in the item screen, then pick 1 fruit and 1 dairy. Every other try or so (depending on your skill level) you should create "Coconut Milk" which sells for every 1000 Fol a piece!! You can also take 2 vegetables and make "Fried Vegetables" which sells for over 2000 Fol a piece! Keep creating the food until you run out of ingredients then go sell everything you created, buy more ingredients and do it again until you have the desired amount of money you want.

Easy Level Up  -  Use Reverse Side to make a forged medal, and then duplicate it as many times as you want to with Reproduction. The forged medals bring a character to 1 point under a level up.

Discovering Talents  -  When you learn the super specialty skill "Orchestra", and have enough songs and instruments for each character, use this skill and for a short time, you will be able to create items without the necessary talents. (For Example: cooking without the talent "Sense Of Smell".) While the song is playing, you will have the chance to learn a new talent by using your specialty skills. (For Example: While the orchestra song is playing, use the cooking "Machinery" skill to learn the talents Dexterity and Sense of Design.)

Become Extremely Powerful in a Relatively Short Time  -  There are several methods to become very powerful that are available quite early in the game, here are a few. 1.In the beginning of the game, there is a mountain dungeon that isn't meant to be faced until much later, thusly the enemies will raise your characters' levels VERY quickly. At first they'll kick your butt, but with every victory you eke out, you'll become stronger [kitchen knife skill makes things easier here, btw] you can build your characters to 3000 hp levels here with some work. 2.Make sure you learn pickpocket [poker face and courage skills] and save up 40,000 bucks. Make your way over to Clik harbor and purchase a thief's glove. Now you can go on a world stealing tour, and get many things. Very notably, there is a man in Mars who carries a treasure box, which when used will dispense three random items. Once you get it, save your game and open it until you get what you want. Though it usually gives you items and such, it occasionally gives you VERY powerful weapons including the Force Sword, the Sorceress Knuckle, and the very rare and powerful Marvel Sword. 3.Later in the game, in the colusseum, the A-class battle earns you right around 100,000 exp, and allows you to quickly build levels until about level 105 [note: Level 90 is adequate to beat the limited version last boss] 4.On one of the snowy islands near Giveaway, there is a shop that sells magical rasp, which allows you to create the most powerful weapons and armor in the game.
