What mobs drop Dark Scroll for Earring 30/70%?

Hey

I was wondering what mobs drop these scrolls? I've searched online and most places say that they just don't drop or that the only place that they are is the boss Cygnus boss.

I was wondering if there are other places where these scrolls drop?

Thx <3

 

Int? Dex?

 

Both lol. Also luk.

If there's no monster listed, then it could probably be a Gachapon only item
