I haven't messed with weapons yet, but for armor.. I Make the Piece I want, Imbue 2-3 Resist pieces so that I still have 2-3 properties left, I enhance it, then if I succeed, from there I will choose if I need to fix the rest of the resist or add extra properties that I need.
I did manage to make my 100 LRC, all 130 Peice Luck Suit for my gargoyal. though you can't add luck into earings, or neckless which I think is BS since hats, and gloves for humans can have luck....
