What Every Mapler Should Know

That would be one of the singularly most stupid things ever.
For one thing, they stack, and they can't have different RNG's in a stack. Since they clearly do not all have the same success/fail in the same stack, I call BS.

What makes you think that?
Scrolls stack in your inventory. That means they don't have an individual continuous existence the way equips do. Therefore, they couldn't keep a "is going to work" field even if they had one.

[COLOR="#FF0000"]Single scrolls have been tested before with a lot of painstaking examination. I don't know how stacks work, perhaps there is a "is going to work" field that has the whole stack set to one that goes through the RNG again when the top scroll is removed.

I could probably prove it to you, but it would take a lot of work and I've lost my own touch with that sort of thing since I stopped coding for private servers and such two years ago.

Edit: Also, if it was in fact done while you were scrolling and a way to exploit that was found, and believe me, it would, white scrolls wouldn't be so abundantly duped. [/COLOR]
