Starting a battle with full ATB is usually only possible with Pre-emptive Strike. However there is a way to start the battle with full ATB without this. At the start of battle, simply perform a Paradigm Shift to instantly fill the ATB gauge to full.

Tame a Don Tomberry, which can be found at Bresha Ruins 100AF as rare spawn. Use "Battle Mania" to increase your chances of finding him and "Monster Collector" to increase your chances of capturing him.

Perform one hundred consecutive preemptive strikes. If you make a mistake, reload a previously saved game. Make sure to save regularly to keep your progress intact.

Get a "Perfect!" rank after the following quick time-events.

Episode 2, Bresha Ruins AF005: Paradox Alpha.
Episode 2, Bresha Ruins AF005: Atlas (Weakened).
Episode 3, Sunleth Waterscape AF300: Royal Ripeness.
Episode 4, City of Academia AF400: Zenobia.
Episode 4, Augusta Tower AF200: Proto fal'Cie Adam.

Note: 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 reach the area southeast of the safe zone (where Chocolina is located). Find the escalator, which should be blue (going up). If it is not, find its switch to 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. Within a few hours, you should have gained a lot of CP and Gil. Note: This location was selected solely because of 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.
