Armor of Darkness

You create a black, shadowy suit of armor around your body, providing you protection and concealment. You gain a +3 bonus to your Armor Class while the spell lasts. This AC bonus does not stack with armor you are already wearing, but does stack with any kind of shield you have equipped.

You gain advantage on stealth checks made while in any kind of dim lighting or darkness while the spell lasts. The spell takes the form of plate armor or something similar, covering the whole body and any gear you're wearing, including your face, obscuring your features. You gain [sense]darkvision[/spell] out to a range of 60 feet and can see in bright light or daylight without disadvantage if you cannot normally do so. If you already have [sense]darkvision[/spell] then its range is extended to 120 feet. 

You also gain resistance to the radiant damage type while the spell lasts.
