Sphere Company 211
When you beat Gabriel Celesta in Cave of Trials, you can go above Floor 100 in Sphere Company 211. As the name implies, It has 211 Floors. Valkyrie awaits you at Floor 210 while Iseria Queen is at the Last Floor.
The Ancient Books
After defeating the Mudman, head out West out of Peterny and then go to North to Surferio. Find Roger S. Huxley there and talk to him. He'll give you the Ancient Books (if you agreed to take him along in Duggus Forest).
Easy XP/FOL
This trick is only available near the end of the game. Once you return to Elicoor the last time visit the outfitter in West Peterny. Check to see if the item Durian Stun Bomb-R4 has been invented. If not you might have to invent it yourself.
Once the shop has the item, buy 20 of them. This should be about 200,000 fol. Don't worry though you'll get that back and more. After you have 20 bombs, head to Irisa Plains. There will be the white winged monsters roaming the field. Go up to one and start a fight. As soon as you can use items, use the bomb. Instant Win.
Now in order to get a ton of EXP and FOL you need to get in a battle a make a bonus battle occur and win. After this happens repeat the bomb trick. When your chain starts to have 300% and 200% fol, you will see the trick at it's best. With two of the white winged monsters defeated at once you gain about 12,000 EXP and 33,200 Fol. When you run out of bombs, go to Peterny, buy some more, run back, then repeat.
This trick is ideal for people who want to level up to very high levels in a short amount of time, collect hard to get battle trophies, level up low level char, get lots of Fol. An example I will show is that in about 5 minutes I got a level 1 character
to level 40.
Norton's hideout code
The code for Norton's hideout is "256". It is easy because the bandits are dumb.
Peppeti Rosseti's autograph
At the hotel in the begging of the game, get to the floor with the battle system just outside of the lounge to the right, near the man standing in front of the door being blocked. Go past that and the next door will hold a brief intermission sequence. You will get Peppeti Rosseti's autograph on the back of your shirt. It will remain there as long as you wear the shirt.
Better item creation
When creating an item, choose original creation. Set the price of the original creation very high (over 4,000. After the meter completes the first finish, check the characters' expression.. If they are smiling (better if three of the characters
are smiling), then press X to see what you have created. If it is unsuccessful, load the game. This is risky where money is concerned. Note: Setting the item original creation price very high increases the chance of creating good items. This requires some patience.
Finding exits
If you cannot leave an area, talk to everyone there.
Use of the Rabbit Ears Chalice
If you do Roger's Ancient Book Sidequest, you'll eventually uncover an item called the Rabbit Ears Chalice in the Ursa Lava Caves. With the item equipped, enter the code below during a battle to have that character blow up and deal damage to the enemy.
Code - Effect
Up, Up, Down, Down, Left, Right, Left, Right, (Circle X or X Circle, depends on refinement) - Character explodes and deals damage.
