If you get Azura's Star, you don't need to use Grand Soul Gems to trap Grand Souls. Azura's Star is a reusable soul gem.
Really?
CooL!
Hey that means I can fill it up with Grand Souls like Minotaurs and fill it up and fill it up again and again?!
Oh man that's infinite Grand Soul Gems!
And that also means infinite weapon/armor enchantments right?
How can I obtain one?
And the grand soul gem has a "common" soul in it.
HUH?
Why does it have a Soul in it? It's supposed to be brand new. I remember buying some, but forgot the place..
Where can I buy empty Grand Soul Gems?
You get azuras star by doing the quest for the daedra god/shrine
So where can I activate the quest for the daedra god/ shrine?
