Set the Class as Cleric before battle, equip the Divine Favor skill during/before battle, and use the skill and win a duel against an opponent to get the boost.

Since I don't have it myself, I'm guessing the boost either immediately reseted directly to zero or per stage, and either via offensive or defensive loss.
