Well so far so good, not many were here For the Daimyo World Boss but we managed to get to the 9th (didn't pass it so no 3rd convoy).

First convoy drop Originam Book of Han, didn't get it but I assume it's 10%, because

Second convoy drop Original Gikeiki, 135Hp (28 per level) and +10% attack.

Also got top 10 and a finisher (with 150 Kobans )
