Final Fantasy Tactics Walkthrough

Another uphill battle increases the overall difficulty, so try to get as many characters with Ignore Height or high Move stats as possible, then beef up their Move further with items like Battle Boots. The faster you can take out Meliadoul, the better, because the Summoners and Archers are out of range at first and will just compound the misery until you can finish the battle. Someone with Holy will be extremely helpful here because you can lock it on to Meliadoul and it will hit her and only her even if she moves.

Meliadoul uses skills that have a 100% chance of breaking your equipment, so the faster you can stop her, paralyze her, kill her, or steal or break her sword, the better. Alternatively, the Maintenance ability learned from the Chemist class can nullify her ability to break equipment, but using it does require you to give up on other support abilities. You might be better served to just take off your best equipment and use some slightly older stuff, because even if your equipment is protected, Meliadoul's abilities still do a lot of damage. Teleport is a great skill for this battle, and it's fun to watch your characters appear behind her apply a beating, so give that a shot as well. She should be your prime target, though you might have to take enemies out if you're climbing your way up to her. Try to pick away at her from range so that when you do reach her with your front line soldiers, it won't take long to finish the job. When you knock her to critical HP or KO her, she'll teleport away.

As you move on, don't forget to replace any equipment that might have gotten broken!
