Nightmare x15
You can complete this mission effortlessly by playing through the new Story chapter, but if you want a shortcut…
Garland’s Lost Chapter: Cycle of Battle Pt. 7 (Normal difficulty) has 5 Nightmares in 3 waves, completing the mission in 3 fights.
Scorpion x40
Relm’s Lost Chapter: A Thousand Words Pt. 6 (Normal difficulty) has 5 Scorpions in 3 waves, completing the mission in 8 fights.
