Easy Gil and CP
This trick requires a turbo controller with auto-fire capability and a team that is able to win every random encounter in Academia -400 AF- without switching Paradigms or using items. Go to Academia -400 AF- and make your way to the area southeast of the safe zone (where Chocolina is located). You should find an escalator. It should be blue (going up). If it is not, find its switch and make it blue so you do not end up at the bottom of the escalator. Face the escalator and set A to auto-fire. You will swing your sword wildly at the air when an encounter is imminent. In a matter of hours you will have lots of Gil and CP. Note: This location was selected solely for its proximity to the safe zone, but anywhere outside the safe zone will work as long as your wild sword swinging does not move you into the safe zone. Academia -400 AF- was selected because it is the only zone where you can have random encounters while standing still.
