Magia Exedra - Witch of Good Fortune [Nightmare Mode]

You want to clear the fight as fast possible otherwise she's gonna stack ATK and SPD buffs. You ideally want to kill her before she uses her big attack, since it's pretty hard to survive it if your characters don't have an elemental advantage, but it's doable with a good defender. Surviving it the second time is almost impossible though since she will have too much ATK by then. Ayame is pretty good since she can not only remove the DMG buff the boss use right before her big attack making it easier to survive it, but she can also remove the break resistance buff, which can be crucial for a boss you want to break quickly.
