Hi everyone I am WuTang from server 865 and I have been looking forward to being able to use Yamato with my level 83 Earth Main for quite some time, as the Ninjutsu boosts they give each other makes Yamato's Wood Style-Beam attack (inside his barrier) amazing for damage, at an 80% Ninjutsu boost. Also, having recently received Cloak Sakura, giving her the 40% Ninjutsu Boost is also going to be beneficial to me in the long run, as she's going to do a lot to support my Angel Konan and keep Yamato and Main alive past their 2 round immunity. So as you can tell, I was very much looking forward to Yamato's books coming through, which they did this morning. However, after receiving the first book from the Arena Trial event for free, I upgraded his mystery to +1...and nothing happened. OppaiPaizuri says that the book gives his mystery prompt status, which I believe it does in China, but mine is not prompting. He still waits his turn to add his barrier, which means I am still wasting valuable round 1 damage, a guaranteed combo, and a standard attack slot by having him in. Can anyone offer any insight as to what's going on with that? SHould I report it to OAS support?
