Normal/Rare/Epic/Unique Items

so from 1 to 2 stars is 80% chance 20% break chance?
from 2 to 3 is 70% versus 30% break chance?

or why are you only talking about the first star?

According to the scroll.. It doesnt say about percentage. HOWEVER One user from Insoya/Tespia User called Nexon[phone call].. and asked about the percentage.
0star -> 1star 90%..
1star -> 2star 80%
8tar -> 9star 10%
9star -> 10star I dont know about this one.
