Runes are probably the most important thing in this game and the upgrade success rates are an insult.
The mana required to get a few 6* runes to +9 can take you days/weeks to farm.
The prices they charge for buying manastones is almost blackmail.
If you were able to hack this, you could run dungeons legitimately with less chances to get banned..
Does anyone know if rune upgrade chances are checked server side?
