The Noctic Ward
This set of items was created by a single blacksmith so afraid of the dark and the creatures of the night that he studied the magic necessary to combat it. Despite his best efforts, he failed and instead created a suit of armor that would do the next best thing. The Noctic Ward does not combat the darkness, it forces its wearer to become the darkness. This strange property has caused much stigma around the ward, and many adventurers who possess some of the articles hastily throw them out upon learning of their mysterious origins.
The set has rarely been brought together, but when it has, it has transformed its owner into a creature able to sneak up on shadows.
