Hey guys, I've got a couple of questions regarding the number of seal scrolls needed to recruit rare ninjas. I've read that, on average, 60 - 70 seal scrolls are required to acquire a rare ninja from the treasures. What I'm not sure about is that whether these seal scrolls need to be used together or whether they can be spaced out in batches of 10 or 20.

My second question is in regards to that I've also read that the treasures can reset? If that's true, how often do they reset, and if I wanted Sasuke Susano'o, for example, would I have to dump like 900 seal scrolls into Kage treasure at once? Lol, I apologize if these questions are *, but I've been drawing from Kage treasure whenever I managed to get my hands on 10 seal scrolls, so if it's better to hold on to the seal scrolls until I can do 7 multi-pulls at once, then please let me know if that's what I should be doing :)

I'm not f2p, by the way. Thank you in advance!
