with my $100 (8000 ncoin) i got Aden +10
i used 50+ of my cloak enchant on cloak until i get to +7
i used the 2x 10% increased enchant to make it +9
and used 1stable cloak to make it +10
i think u just need to be lucky i got 72 LUC at that time. i might be lucky on making it +10 but making it legendary spent 23 legendary scroll
