Status Plate

A Status Plate (ステータス・プレート) is a common artifact in Tortus that is used as both a form of identification, and as a way of showing one's current stats of the person it is assigned to. They were first created by the Liberator Oscar Orcus.

Description
Status Plates are rectangular silver plates that are twelve centimeters wide and seven centimeters tall. They are inscribed with a magic circle, where a person places a drop of their blood onto, in order for it to recognize them as their owner. The plate would then change its color depending on the color of their owner's mana. After receiving their blood, a Status Plate can display the stats of their owner whenever they say "Open Status". It is possible to keep the plate in either an activated or semi-activated mode. There is also a feature that lets a person alter the numbers on display. People would make use of it in order to prevent the wrong individuals from getting access to their information.

Status Plates are currently the only artifacts that are in widespread circulation throughout Tortus. They are produced through a mysterious artifact that was believed to have existed since the age of gods. Every year, new plates were produced under the strict supervision and control of the Holy Church.

Applications
A Status Plate's main function is to take various parameters of a person's abilities and quantifies them. It also lists out all the skills that its owner can use. The Status Plates also double up as identification cards, because of its unique feature of changing its color to that of its owner's mana, thus making it difficult to fake them, or to use someone else's. There is also a function that allows the user to hide their stats and skills for privacy purposes.

Another feature of the Status Plates is that they can be used in conjuncture with appraisal magic. If someone capable of using appraisal magic analyzes an item within their area of expertise, the Status Plate will display the information for its user to read.

Trivia

 * Status Plates apparently display the name one chooses to associate themselves as, rather than the name they are given at birth. This is evident by Yue's Status Plate displaying the name that Hajime gave her, instead of her original name "Aletia Galdea Vesperitio Avatarl".
 * In the Anime, Status Plates are shown to have a small chain with a cross-shaped ornament attached at the end. It is unknown if they are included in the Light Novel, but it is not shown in the Manga.
 * Prior to the invention of Status Plates, the Holy Church would determine a person's job, stats and skills by using a magical tool in the form of a portrait of Ehit that could only be created through a special forge in the Divine Mountain. These portraits were placed in each of the church's cathedrals, and each person was required to be examined by it once they reached a certain age. When someone touched it, their mana went into the portrait, and determined how much total mana they had, what their aptitudes for the various fields of magic were, and what their job was. There were mana inhibitors spread out in a line across the edges of the portraits that were used to make these estimations. Because each person had a unique mana signature they went through the inhibitors at different rates and in different ways. If someone didn’t have an aptitude for a certain kind of magic, their mana wouldn’t be able to make it through that inhibitor at all and stop there. In addition, all jobs were classifications made by the church, and the only time new jobs were added to the list was when someone accomplished great deeds in a new field that didn’t already have a job assigned to it.
