So I've recently unlocked GNW treasure, and didn't pull for about 2-3 weeks of unlocking it, I drawn around 10 free pulls, and got nothing from it.
Recently I used 60 seal scrolls, and got toroi, pakura, edo zabuza, and a few other 10 pull ninjas, can anyone explain how is this possible? I thought it would require around 180 SS to get 3 rares, but with 60 I got 3, so I'm confused.
