Belt scrolls, and the 'attack belt'?

Thanks for the confirmation. Any ideas if there are any other ways to get those scrolls or was it just that event?

The 100% scrolls are still littered throughout the FM, but I don't know how people get/got that many. I think there are too many to have them all left over from the event, especially since they are fairly cheap (500k/scroll). Never seen a 10%, and 60%s are expensive/rare. Essentially, idk where the scrolls are coming from, but the 100%s (most likely) are coming from somewhere, and perhaps the 60%s.
