Star Ocean 3: Till the End of Time (Japan) Cheats

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.

Have Roger join your party either as the 5th or 6th character and when you meet Lenneth Valkyrie at Floor 210 at Sphere 211, an extra scene will triggers.

Go into battle with the Gutsy Bunny equipped, then deequip it immediately. Enemies with 100,000 MP or more have their max MP reset at 99,999, making them much easier to kill with MP damage.

With Fate, Cliff, Maria, Roger, or Nel, run to the edge of the screen, then continuously step (hop) into the edge. You will be invincible to nearly all attacks (but not Heraldry).

To unlock Cave of Trials, simply beat the game.
