Epic Changes for MapleStory Weapons!

And how rare is the advanced scroll?

Cause it looks like the advanced scroll is pretty much a free 3 star item.

Using only advanced scrolls, the percent of items you try will get to
1 star: 100%
2 stars: 90%
3 stars: 72%
4 stars: 50.4%
5 stars: 30.24%
6 stars: 15.12%
7 stars: 6.05%
8 stars: 1.8%
9 stars: 0.363%
10 stars: 0.0363%
11 stars: 0.00363%
...

Using regular scrolls
1 star: 80%
2 stars: 56%
3 stars: 33.6%
4 stars: 16.8%
5 stars: 6.72%
6 stars: 2.016%
7 stars: 0.403%
8 stars: 0.0403%
9 stars: 0.00403%
...

Not great odds but up to 6-7 stars will be fairly common if people can get their hands on mass quantities of Advanced scrolls. Or up to, well... 4-5 stars, really, for regular ones.
