God who resides in Izumo.
Breath of the soul.
Residing in the mountains and watery heavens, Amaterasu.
Let this freely become the proof of purification.
Thy name is Weighted Stone of Tamamo.
Become the sacred treasure, Mirror of Uka!
The Eightfold Blessing of Amaterasu (水天日光天照八野鎮石, Suiten Nikkou Amaterasu Yano Shizu Ishi?, Eightfold Blessings of Amaterasu on the Weight Stone under the Sunlit Watery Heavens) is a mirror that Tamamo-no-Mae wears on her body. It is the temporarily released form of the Weight Stone of Tamamo (玉藻鎮石, Tamamo Shizu Ishi?), a sacred regalia among sacred regalia, which was enshrined at Izumo after being brought from heaven by "Takehinateru-no Mikoto." According to the descriptions of the Nihon Shoki, it was taken from Izumo at the order of the Imperial Court and then later enshrined at Kawachi. It possibly later came to be known as the Yata no Kagami, the divine repository of Amaterasu, and it is thought to be the prototype of the Tokusa-no-Kandakara (十種神宝, Ten Kinds of Sacred Treasures?) of the Mononobe clan, which holds the power to revitalize souls and life-force.
The mirror levitates around Caster in battle, which she uses it to hit enemies in close combat. Once its function as a Noble Phantasm is activated, she summons a circle of levitating ofuda surrounded by a number of glowing torii, charges the mirror with energy, and stands in the middle of the circle to draw in the energy. The energy drawn in allows her to use her abilities without the need to expend any prana for a limited time. It is normally a divine treasure of the land of the dead, an EX rank Noble Phantasm, that can even bring the deceased back to life, but the Servant form of Caster hasn't been granted the authority to use that much power.
