So, to complete my Dark Elf, I had stolen a pair of Dunmer Boots off of a resident at Raven Rock. I was unaware in the first place that you couldn't enchant any kind of boots with fortify whatever mage skill (in this case, destruction for me), so it came to a surprise after I had done this to these pair of boots that I couldn't enchant any other boots like it. Thoughts? Bug? Intentional? I don't know, but it's pretty nice having a pair of boots with 25% off destruction, and 15% off destruction / +10% magicka regen.
