A set of armor once worn by a demon. Demons are incredibly intelligent, some even moreso than humans. This armor was handed out by a war with the humans. Though this armor, which was the culmination of all demonic techniques, posed a threat at first, the humans soon overpowered the demons, then using their own armor against them.
Demon Mail (デモンズメイル, Demonzu Meiru?), also known as Demon's Mail, Demon, Black, or Demon Armor (デモンズアーマー, Demonzu Āmā?), is a recurring piece of heavy armor in the series. It is part of demon equipment set.
Demon Mail is a mid to high-ranked suit of armor that can be bought for 25,000 gil or found at Falgabard. It can be equipped by the Onion Knight, Freelancer, Warrior, Dragoon, Viking, and Dark Knight classes.
Demon Armor is the strongest armor for Dark Knight Cecil, providing 9 Defense, 3 Magic Defense, and -10 Evasion. It can be bought for 3,000 gil at Fabul. In the 3D remakes, Demon Armor remains largely the same, but loses the -10 Evasion penalty.
Demon's Mail is a mid-ranked heavy armor that provides 27 Defense, absorbs Shadow-elemental damage, increases the power of the user's Shadow-elemental attacks, and teaches High Tide.

Steiner and Freya can equip it.
In the original version, Demon Mail is a mid-ranked heavy armor that provides 29 Defense, +5 Strength, and +3 Vitality.
