Good question

It's all about RNG.

You can get 1/2 frags every 60 pulls, but since all SR could be obtained in a range of pulls, it's hard to say.

For my direct experience (pieced hashirama 2 weeks ago) i used around 2.7k scrolls and i got a kurama dupe (3rd SR) around 40-50 scrolls before finishing it.

Memo instead pieced him with less scrolls but didn't get the 3rd SR untill he went way past the 3k seals mark.

I am going to break it down.

Let's say you get it at the 1000 Seals:

1 Fragment per 60 pulls = 16.6 Fragments

2 Fragments per 60 = 33.3 Fragments

1.5 Fragments(Average it out) = 24.9 Fragments

Now if it takes 1300 Seals

1 Fragment per 60 pulls = 21.6 Fragments

2 Fragments per 60 = 43.3 Fragments

1.5 Fragments(Average it out) = 32.5 Fragments

Ranging between 16.6 - 43.3 Fragments based on RNG.

So the mean would be around 29.95 based on all the variations.

This is just an estimated value as I do not know the exact rates hashirama's fragment drops.

If you lost count, just count ammount of rares you have and ammount of 20 frags of each rare (duplicate pull) and multiply that by 60-70 (ammount you need to pull a rare). If you havent bought sasori frags before in events, that should give you rough estimate on how much you pulled.

my friend got it at 28 fragments but im still at 32 frags with nothing lol

31 frags of hashirama with 1150+ scrolls used, still no S rare.

I'm currently at 31 edo hashi frags with 1210 SS and a super rare

I got Kurama Naruto at 1030 into GNW and I have 27 Edo Hashi frags

so i need to frags..20 to go sigh..math for me

26 frags for me to get Naruto K.

31 frags for my friend and he got Madara

34 frags for another friend but still not enough for him to get any super rare lol

I'm at somewhere in the 1800 scroll range right now (not 100% sure because I stopped counting the free pulls), but I've done 5 300 pulls, 2 100 pulls, and a bunch of random 10 pulls.

Got Marada at around 1170.

53 Hashi frags right now.

So roughly 1 frag every like 30-35 scrolls. Depends on the RNG. Generally you'll be in the high 20's or low 30's when you get an SR.

910 seal scrolls = 35 edo hashi + kurama naruto

i'm a F2P by the way

i got some frags in free draws many times

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
