Shroud of Night

A shroud of night grants you a number of shadow-oriented defenses. A shroud of night is a very lightweight cloth, made of a thin, gossamer material. It is always black or dark gray. When worn, it ripples slightly even in the absence of any wind or movement. The shroud wraps about the shoulders but occupies space on the body as a vest, not as a cloak. The deflection bonus is active constantly while the shroud is worn. Using dancing shadows or shadow skin requires a command word, such as "nightfall" or "obfuscate."
A shroud of night grants you a +2 deflection bonus to AC. It can also cast the mysteries dancing shadows and shadow skin each once per day, on you only.
