My server is only a few days old. I noticed that the page on the seven days icon(the one with orochimaru where you claim 11 seal scrolls for using 40 in the last days or w.e) isn't there. Does it appear once you've used them?

Does each bench mark with them stack, meaning if I spend $ to draw 40 seal scrolls, will I get that additional 11 scrolls?

Also, if anyone knows. What are the most common 3 star draws from seal treasure?
