This massive set of plate armor seems almost too heavy for a normal person to wear, with oversized pauldrons that lead into a very thick back plate offering excellent protection at the cost of the weight you'd have to carry.
To a worthy person, however, this armor is as light as a feather. The thick back will unfurl into large metal wings, giving the wearer a fly speed of 30 feet. In addition, if the wearer is not flying they can use a bonus action to give themselves half cover, using their large wings as protection.
The wearer has disadvantage on dexterity (stealth) checks. If the wearer's a strength score is less than 15, their movement speed is reduced by 10 feet. If they are attuned, however, there is no strength requirement.
Note: I am not the original author of this item. I just added it to D&D Beyond™ with a few language corrections and the proper modifiers to remove the strength requirement and add the flying speed when attuned. I am not able to reduce the weight, so you'll need to manually customize the item after attuning.
Plate consists of shaped, interlocking metal plates to cover the entire body. A suit of plate includes gauntlets, heavy leather boots, a visored helmet, and thick layers of padding underneath the armor. Buckles and straps distribute the weight over the body.
Notes: Set: Speed (Flying), Ignore: Heavy Armor Speed Reduction, by a cleric or paladin, Movement, Warding, Str. 15 Required, Stealth Disadvantage
