I mean honestly, I really don't understand. It's enchantments are exactly the same the TG master's, just 5% better. It's more of a letdown than Linwe's. It doesn't have any real benefit to combat, or any kind of skill that would have any use at all. Pickpocket/Lockpicking is completely useless. Bartering can easily be compensated for, so the only remotely viable enchantment is +50 stamina, which Nightingale already has; just instead 40 points. A wasted opportunity, in my opintion.

Bonus. but yeah they could've given it unique enchantments or at least a new model. i took it from the basemant but i never used it because of the things you listed.

Well, it was his old Guild armor, so what did you expect? He's a retired thief. You don't have to use it; to me, it's a nice set for my collection of armor and to others it has a certain role playing value.

Too many of the unique armors adorn my shelves for collections. I want to actually wear armor that I didn't craft for once
