Nightwing's Veil is a unique Spired Helm. Due to its boost to all skills, in addition to a boost to Cold skill damage, Nightwing's Veil is particularly popular among characters such as Sorceresses that use Cold Spells, Amazons that specialize in abilities such as Freezing Arrow, Iron Wolf hirelings specialized in Cold Spells or for Paladins that are using Holy Freeze. Nightwing's Veil is the only helm in the game that increases cold skill damage, making it usually the best helm for such classes by a considerable margin.
