Nightingale Bow

thingiverse

The Nightingale Bow is a one-of-a-kind archery weapon that can be found in Skyrim. Originally owned by Karliah, it can be obtained during the Thieves Guild questline. As the bow is leveled, its enchantments, base strength, and value are directly tied to character level. This means that with every level gained while possessing the bow, damage output increases, weight and overall worth also rise.
