A single piece of armor isn't useful for much; it struggles even to stop arrows from the Natives' short bows.
But hundreds, even thousands, of these armor plates linked together to form a whole can make up the external defense module of an Aether Armament, capable of blocking the fangs and claws of Magical Beast Alien Forms or the bullets from Alchemical Firearms.
If you then add the power boost from an Aether Furnace Core, it can even block Alchemical Cannons!
Ultimately, that is the most powerful trump card of Viscount Grant, the Governor of Harrison Port, used to suppress the surrounding Natives. Naturally, the more spare parts for this defense module, the better.
Though in theory, these basic inscribed armor plates can be made by any Initiate Inscription Craftsman, not everyone has such steady hands or the trust of the Viscount to be given this evidently crucial and error-intolerant job.
Moreover, inscribing such an armor plate took Ian close to half an hour.
