Faith Boost

From Final Fantasy Wiki

Faith Boost, also known as Face Up, is a reaction ability in Final Fantasy Tactics. The Bard class learns it for 500 JP. Whenever the unit with this ability takes damage, they will boost their Faith level, making their magical attacks more effective, but will also become weaker to magical attacks. Since this is a Bard ability, only male characters can learn it. However, Alma Beoulve automatically has this reaction ability equipped when she joins Ramza's party during the final battle against Ultima in the Airship Graveyard.
