Okay, I feel like I've got a solid team down for the fortnight. Double Sengoku, Dock Kaku, Braham, Log Nami, and Breed. Use Braham on Nami's stage (since taking her down in one turn is extremely hard due to the ATK debuff), use Log Nami if needed to take out Nami on the next turn, then use a Sengoku and Kaku to take out Robin in one turn. The team also has enough HP in case I need to take a hit from Robin.
Drops are interesting. I got a lot of Robins last night, but today I'm getting Namis. Lots of 3D2Y Nami and Usopp books, which sadly I have to ditch due to not having either and not having the space to hold them. Not a single 3D2Y Luffy book yet, and only one Story Absalom book, which is odd (and disappointing, I've actually used him a few times).
My primary goal with the fortnight is to socket 3D2Y Robin, but I'm not expecting to finish her 100% here and that's fine, since Kimono Hats 2 is coming sooner or later, and there's a lot more for me to farm there in general. I'll wait for that fortnight to go nuts with stamina refills.
