Ebony Mail

Ebony Mail is one of the most powerful cuirasses. If judged worthy, its power grants the wearer invulnerability to all common magical attacks that drain talents and health. Eternal Champion was one of the owners of the mail. It was hidden in Black Marsh after the previous owner, a warrior named Helath Stormbinder, lost the favor of Boethiah. Following a strange map, the Eternal Champion eventually found the resting place of the mail and retrieved it for his war against Jagar Tharn.

Later on, Boethiah also rewarded the Ebony Mail to the Hero of Daggerfall, after he finished a simple elimination job.

Skyrim
In Skyrim, the player is awarded the cuirass after completing Boethiah's Calling. This cuirass grants the wearer a version of Muffle and also deals 5 poison damage per second on enemies near the wearer. Another unique feature of the Ebony Mail is a shadow that covers your entire character while you're crouching with the mail equipped, and small tendrils of shadows will leak off of you. This visual effect makes the player feel like it should be rather more difficult to be detected by NPCs, especially when combined with other muffling and/or sneak-boosting equipment, though the shadow effect itself may likely be just that: visual. Most NPCs won't notice you until you are within an extremely close proximity while wearing this armor. When aiming with some bows while wearing this armor you cannot see your sights, nor your target because of the tendrils that leak off of the Mail once crouching or in combat. This is rather unfortunate, considering that the armor makes you almost undetectable. Moving forward very slowly lessens the blinding effect.
