"On the wings of a wyvern"

Float like a feather, and have some AC...

 This unique half-plate is made up of a finely crafted steel plate, and intricately woven wyvern scales. This half-plate armor seems to grow lighter when you inhale. You can hold your breath at any point to both lighten the armor and quiet its clattering, negating the normal disadvantage on Dexterity (Stealth) checks imposed by half-plate armor. In addition, if you fall while wearing this armor, you can hold your breath as a reaction to cast the feather fall spell, targeting only yourself, at will. This can only be done once per day, with the expended charge resetting the following day at dawn.

You have a +1 bonus to AC while wearing this armor.

Half plate consists of shaped metal plates that cover most of the wearer's body. It does not include leg protection beyond simple greaves that are attached with leather straps.
