Final Fantasy Tactics Walkthrough

Before the next battle begins, Ramza and Folmarv have a tense meeting. The fact that this is a battle chapter in the walkthrough should help clarify how that meeting is about to go. Ramza tells Folmarv to release Alma, but Folmarv asks for the stones and the Scriptures in advance. Ramza negotiates, telling him he'll get just the Scriptures, not knowing that the incantation contained inside the Scriptures is actually more dangerous at the moment if left in Folmarv's hands. After Loffrey gets the Scriptures for Folmarv, he glances through it and finds the information that he needs, then Folmarv's group attacks to collect the stones anyway.

You don't even need to defeat Folmarv specifically, just one of the three enemies coming for you. Holy will do it, but if you're using Orlandeau, just send him up and have him use Hallowed Bolt on Cletienne. There's a good chance this will one-shot him, and then all three will run away. It's a very simple battle that shouldn't be difficult at all at this stage of the game. Even without Orlandeau, the battle can be quickly managed by targeting Cletienne with the bulk of the party. Folmarv escapes into the basement, and naturally the pursuit continues.

Equip Japa Mala on everyone possible, and save the game in your secondary (or tertiary!) slot. There's one more battle before the next possible break.
