Scroll for shield for magic att. 60%

Hello, I saw an old threads about this scroll that says you can get this scroll through gach only. But that was before Ninja Castle was added to the game. According to hidden street website, Jonin and Kacchuu Musha monsters drop that scroll. Are they really drop in the game, or is it still gach only scroll?

My understanding is that you can only get them via gach in mapleroyals

 

It was removed from their drop table, it's gach only.
