The Armour of Agility is a legendary Medium Armour that doesn't limit your AC's Dexterity bonus.
Layered sheets of smelted, shaped, and smithed steel have been etched with a sweetly luminous gold. Its outward appearance is heavy. And yet it's so light when you lift it, like lifting a bag of shrunken dead leaves.
