You have to defeat at least 15 Doll Queens that are spawned by the Neo Generators, while not killing the Eastern Sage. The Neo Generators will cast Seal, Blind, Poison, Paralysis, and Petrify on your party so you need to protect against that. If you can keep the number of dolls at 2 or less, the Generators will always create another the next turn. This stops them from casting a harmful spell on your team. 2 Star Reward: 3 Mana Prime
