Ok, so I found a chest piece called the Scaled Horn Armor on a vendor in whiterun of all places. For some reason it won't let me upgrade it on the bench. Since I am lacking in blacksmithing perks, I cannot improve it after enchanting it, so like all my other gear I attempted to upgrade it first, no dice, it does not even show on the list. Anyone know why that might be?
I don't think that you can improve the horn variety of the scale armor. Either it was an oversight, or they simply intended to make that variety of armor for the visual flair of the animal fur and horns on the shoulder plate.
I had all of the relevant perks and materials, and it doesn't show up on my list either.
