Art
The Art Specialty can also produce very helpful support and recovery items. Make sure to have someone with the right talent to specialize this skill.
Maze Of Tribulations
Use the save point immediately before fighting Gabriel. Once the saved game icon turns blue, return to the arena in Fun City. Talk to the old man in the audience in the north side of the arena. Accept his offer to recover your memories. You will return to Arlia on Expel. Leave Arlia and you will have your Psynard. You can now find the hidden Maze Of Tribulations dungeon at the lone dot on the desert island that is located southwest on the world map.
No Encounters in Dungeons
Like the other Star Ocean for PSP, if you open the disc tray while in a dungeon, you will not face any battles. Just remember to close the disc tray everytime you change screens (causing it to reload data), or before boss fights.
Voice Player
Beat the game once on any difficulty, and you unlock the Voice Player. Beat the game with additional characters in your party to unlock their respective voices.
Weapon Sharing
If there are anybody in your team that are using the same weapon, have one of them concentrate on leveling up his/her customization skill. This way, you will only need to have that character forge the weapons and share it with the other, saving SP.
