Items that boosts Maker?

It would be cool to be able to make your own scrolls with maker using jewels, stat crystals, (tons of) monster crystals, and blank scrolls (from gachapon so that nexon doesn't lose money).

The real question though would be dark scrolls -

Would you only be able to make light scrolls ( high medium low crystals making 10, 60 and 100% respectively) or would dark scrolls be a possible "failure" result? or even a result of using black/dark crystals adding a chance for the scroll "turning"

The latter would be more interesting, the higher the quality of the black/dark crystal the higher the % of yielding a dark scroll.

I don't agree with blank scrolls being gacha though - If they had to make money off it Nexon could make far more money making blank scrolls a straight up cash shop item. People would be more likely to directly buy them than to gamble for them.

Otherwise making them achievable in game somehow would be preferred.
You could go all out - You have to do one series of recipes just to make the blank scroll, then another set to use them.
