so about every 60 to 70 pulls you get 1 or 2 hashi frags. Usually every 60 pulls i was at 32 hashi frags before i got madara. Hope this helps

To be clear i have been pulling for hashi and every 60 maybe 70 seals i get hashi frags. Now depending on my RNG they are either hashi x1 frags or hashi x2 frags. Meaning every 300 seals used you can have anywhere from 5 - 10 hashi frags with 10 being optimal which almost never happens so somewhere between 6 - 9 in reality. So one person can get 36 hashi frags and only have used 1200 frags the first super rare drops between 950 and 1300 frags depending on RNG
