I was enchanting my elmore +7 legendary cloak and it dropped below +7, i used the scroll enchant cloak and now it is +2, the succes rate of the combination legendary cloak and the scroll enchant cloak is bad, i forgot the exact number but at +6 it was 34% or something, now at +2 it says success rate is 63%, but this guy in previous forum posting said this
"I used it at +9 and made 10 i think it was around 64% chance to +10"
If that is correct then there is something wrong with the success rate with the combination legendary elmore and scroll enchant cloak.
