Just curious as I just noticed this option when i just made my enchanting 100. I now have a ring with 50% frost/fire resistance, and a necklace with 50% shock resistance and 43% one handed damage increase, to go along with the nightingale armor. So i don't think i will need to do much more enchanting.
Anyways, i was just wondering if its worth it to make any skills legendary? pros/cons?
