It makes no sense to twist it once, one chance out of sixteen.Ten procurts cost 500 coupons, even if you get one fragment at a time, then 80k coupons will be released on the ninja. But it may not fall out, and then about 100k coupons. How many players have and want to spend that much? And they give you like 10 minutes to spin, will you have time?

P.S. At 10, it turns out 60% that it will fall out and 30% will not fall out, not enough.

I will add, scrolled 200 key (20 spin) in Great plate, and how many Sasuke fragments i got? One .... ONE Carl, in Amount could be even worse.
