Boost (ability)

Boost is a recurring ability that increases damage.

Final Fantasy III
Used by Black Belts. Using it once increases damage dealt, while using it twice increases damage further. Using it three times will hurt the Black Belt and release all the stored energy.

Final Fantasy IV
Technically, not called Boost, Yang's ability Power allows him to forfeit a turn, and attack at double power the next turn, much like many other incarnations.

Final Fantasy VIII
Guardian Force attacks are enhanced by Boost via timed button presses.

Final Fantasy IX
Boost is a support ability that enhances Garnet and Eiko's summons.

Final Fantasy X
Boost is a command that is available to the Aeons if you press right on the command menu. It allows the Aeon's Overdrive gauge to fill up quicker, at the cost of the Aeon taking more damage. It's the opposite of Shield.

Final Fantasy XI
Boost is used by Monks. It raises the next attack for approximately three minutes and is stackable. It works well in conjuction with Chi Blast and to increase enmity. Boost can be enhanced by wearing Temple Gloves.

Final Fantasy Tactics Advance
Boost is usuable by Archers. It increases their next attack. The Templar's Cheer is identical.
