What Every Mapler Should Know

Single scrolls have been tested before with a lot of painstaking examination.

Remember the meso exploit rollback?
Before it I scrolled a weapon, 5/7 60's passed.
After the rollback I had to scroll it again. 4/7 of the same stack of 60's passed.

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.

Do you realize how absurd that is, from a coding point of view? Why generate a "going to work" for each scroll, if you're only going to lose it when you stack them? And then generate the success state of the next scroll when you use/drop/sell the top one from the stack?
So much easier to roll the success when the scroll is used.

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.

If a way to exploit anything is found, it would be, of course. In fact, I would think that a pre-determined "will succeed" would be much easier to exploit than one that is generated on the spot by the server.
