Immediately eliminate status effect
While in battle sometimes monsters will perform attacks that cause changes in your otherwise normal status. (Such as sleep and paralysis.) When this happens it is possible to easily rid yourself of these two status changes by simply pressing the B button (blue button) when the turn of the player with the status change comes up. The dialog box at the top of the screen will say for example "Gre is alseep," and show a close up of your character, now press the B button and your character will be fully awake or fully able out of paralysis on his/her next turn.
Music Test
After finishing the fifth and final ruins, enter the tavern and then check the jukebox. A list of all the music in the game is now available to play.
Save money
To save money when you have another character and you get to the final floor, switch to Gre and defeat the Boss. Additionally, Gre has the power to make the Boss wait longer.
Use Special Moves Without Using FP
To use any special move without using any FP simply wait until you are in battle to master a technique. (This is really useful on bosses)
