Not having enchanted mantle is not the end of the world guys.
Some people don't even have the non-enchanted mantle!
Just because the feature is there, doesn't mean you have to have it.
Go hardcore, be rich, or pray a lot and get lucky!
People can hardly be satisfied.
Those who are yet to get a successful enchant will want a successful enchant.
Then those who got a succesful enchant will want the right rare stat.
Then those with the right rare stats will want the highest rare grade.
I know this because when I got my second +6 red ac, my first genuine reaction (deep within my heart) was "why is it not +9?!!!". Such ungrateful spoiled brat.
