5Atk 3All or 7 atk scrolls on fafnir weapon?

Wait until Unlimited for 20% 9 atk boom if fail scrolls

 Spoiler

so you can spend more NX on protects

They are +3 All STAT too, if I remember correctly. Or wait for the 75%/95% versions of the same scrolls in that one Hot Time or hope for the Hot Time where 100% +10ATT/+3 All STAT scrolls are given out.
