Here are several ways you can get seal scrolls and fragments: There might be more if I missed any

1. GNW packs - attend wars and hope your guild leader gifts you a pack. There are 3 different packs with different amount of seal scrolls.

2. Black market - they appear as fragments

3. Weekly missions - they appear as fragments

4. Weekly log on the mini client - they appear as fragments

5. Monthly Sign-ins (you can get max 2 depending on how much you sign in)

6. Weekly events such as Matsuri (fragments and/or 1 seal scrolls depending on how many matches you finish), sage battlefield (top 3 in your field), rescue the jin (fragments in packs),

7. Weekend missions - Puzzles (fragments), TI scrolls (can't remember which one), Lucky Throw (you have to land on 12?)

8. Sealed ninjas/treasure (1 scroll for each ninja you kill but it is max 2 per day you can get rewards and they are random)

9. Survival trial and trial breakthrough - a higher chance of appear in trial breakthrough and 8-10/12 of survival trial

10. Ninja quiz - getting 10/10 allows you get a chance of getting 1 seal scroll

11. Chase missions - the ones I'm aware that give out 1 seal scroll are the vanilla naruto and sasuke mission

12. Space-time - 1 fragment for 5000 betting coins, the rewards for participating in space-time finals
