Final Fantasy Tactics Walkthrough

This battle is the last hurrah, so don't drop the ball after coming this far! This version of Ultima is once again weak to Holy, Holy-typed attacks, and Lich spells, so use those to their full extent. Ultima is alone here, so it should be a pretty easy battle. Have your healer just in case, but at this point in the game, your characters should be powerful enough where it won't take them but a few rounds to take care of Ultima. Keep moving your units in and out of range as needed, and use your highest-damage attacks exclusively, to minimize the chances of the demon striking back.

Good luck, and enjoy the ending when you win!
