Each of the battles to unlock a Row IV class is a solo battle with the Main Character as your only party member. The class line you choose will determine the Old Woman's charge attacks, charge diamonds, triggers and debuff resistances. The Old Woman's element will be determined based on the grid you are using. If you are using a Fire, Water, Wind, or Earth grid the Old Woman will have advantage on you, whereas if you use Light or Dark she will have the same element.
The battle becomes considerably harder with Phalanx II. You can wait out the 3 minutes for it to pass or you can Dispel it. At 25% Repel can deal a lot of damage and potentially KO you so it is recommended to use Dispel or the Robomi Rocket summon to remove Repel.
