Lynn

Lynn is live in Suburb, when you reveal about Ben and Hurley, she also discuss about they captured brother.

Mission
Lynn request character went Digging  and Pit. Also went unknown pit, when almost there to giant drill machine, Lynn noticed his brother died of accident.

Lynn said giant drill machine weak spot is sugar, Sugar just in Central City of restaurant. After giant drill machine destroyed, Locust tortured and captured Lynn to Locust Camp, This can be asked to Bodden  when promised.

Rescuing Lynn will be tough, you need to defeat a boss with 30k HP with base attack of 30 if you're wearing full iron-pig gear. I recommend that you go first destroy Spider Nest in the Northeast of village near Locust Camp, destroy it with 66666 HP, and you can get Chicken Mask, Longevous Turtle Shell with 999 Def but 200 endurance, Bricks and Toadstool. The most important here is that you equip the turtle shell. I also recommend shotgun for this boss since it has a damage of 1200 when close-range.
