This particular armor is normally worn by members of the Shadow Army. It is given to the regular infantry ranks of them. The combination of metals and minerals found in the Shadow Realm create an almost impenetrable armor. Forged by the Elder Blacksmith inside the Dark Citadel, they are also specially fitted to each individual soldier.
The metal, Shadow Stone, gives off a defensive aura that further protects the wearer. Corrupt Stone smelted with it gives the wearer more strength and other physical boosts.
This is an entry to the contest because it's powerful. And why not.
