Secret Spell Scroll

if it's over 20 secret spell scrolls, in over 10 people's shops, there's almost 0% chance of it being from gachapon, and if they were from gachapon boxes then there would have been a screeenshot or two of people getting them. Also, the multitude of people selling them seems to indicate that it wasn't someone server transferring and trying to bring a good portion of their mesos with them (if this were the case it wouldn't be so many people, or you would have seen these up in people's shops after the last server maintenance if a group of people transferred worlds en-masse).

I'd say it's safe to assume that the dupe hack is back.


Edit: Or the dupe hackers are selling off some of their stash from the dupe hacking last year.
