Chapter 16x: 4/58 Turns
Used the Dragonshield on Dorcas at the beginning, because he hadn't gotten Def. yet. Guy self-improved while Marcus soloed the center pirates, grabbed the Sleep staff, and talked to Fargus.
Chapter 17: 4/62 Turns
Dorcas helped Marcus break through the shamans to the west in order to charge the boss while everyone else held the RHS and/or shopped.
Chapter 18: 6/68 Turns
Marcus did his usual thing of charging the boss (this time with a Horseslayer) while Dorcas and Wil followed behind to clean up the scraps. Eliwood defended Merlinus from pirates. Matthew and Guy went east to bro it up with the pirates and magic users, and hit C support level for their trouble.
Chapter 18x: 7/75 Turns
Marcus cleared the way with handaxes and took out Aion with Guy's borrowed Killiing Edge. Guy and Matthew grabbed the southern ruins while Dorcas and company handled the Pegasus knights.
Chapter 19: 6/81 Turns
Marcus, Eliwood, and Dorcas took the outside corridor. Matthew, Guy, and Wil went through the door Serra unlocked with her staff. Wil sniped the mini-boss, and Marcus hammered Darin. Oh, and Marcus killed Legault for fun/EXP (though he still only got 4 for killing him). I missed all of the chests, too. Swag.
Chapter 20: 5/86 Turns
Marcus and Ninian did about what you'd expect. Eliwood and Wil pulled a few clutch kills on the way to the boss to clear Marcus's path. Dorcas and Guy visited villages, killed mages, and shopped.
Chapter 21: 2/88 turns
Marcus charged south and provoked Eubans, who was promptly knocked down to half HP. Dorcas immediately killed him with a lucky hit with the Devil Axe. I completely forgot that this level ends when you kill the boss (at least, Heath pulled the mercenaries back in my game), so I kinda got caught with my pants down, and didn't really accomplish much in terms of experience or chests. I also missed Rath's and Heath's inventories because the chapter ended before I could recruit them.
Chapter 22: 6/94 Turns
Ninian got Isadora's Angelic Robe in Preparations. I considered promoting Guy, but I decided he'd earn more EXP (toward the goal of 700) as a Myrmidon. The only hidden item I managed to grab was the Ocean Seal, but it was the only one I realistically expected to get. Despite Pent being particularly annoying, I managed to acquire the necessary 700 EXP for Chapter 22x: Free Experience Genesis.
Chapter 22x: 20 Turns (Free)
Not gonna lie: I shamelessly exploited the free 20 turns. Eliwood, Dorcas, and Ninian started on the east side, while Marcus, Isadora, Wil, and Matthew went west. Managed to grab all of the chests and kill all of the enemies and grab all of the shiny silver weapons at the end in exactly 20 turns. Even promoted Dorcas at the end (from a level 18 Fighter).
