|Title:||False Copy of Inscribed Creation|

The weakness in the ability is that it not only requires Avenger to be wounded, but he must also be alive and conscious, as he must consciously activate the ability by chanting its name. It can only focus on a single target, and it is useless against high-level attacks. The damage is also generally not a great problem for a Servant level opponent, as they can still hold up, while Avenger, who is far below the level of an average Servant, will quickly die from such wounds.
It is not as useful as a scripture that returns twice the damage, and this form of reversal curse generally has no effect on Heroic Spirits with strong Magic Resistance. Against Saber's exceptional resistance, it should even make the damage to his own body worse, but once all of its conditions are met, it will completely ignore even Magic Resistance even as potent as that of Saber. It is generally only a distraction or hindrance that works well in combat when paired with Bazett's Fragarach. Avenger would normally quickly die and the wounds won't impede the enemy much, but the threat of Bazett makes the enemy quick to utilize their trump card and become targets for Fragarach.
It is a copy of the Book of Zoroaster, Avesta: The Universal Revelation of Inscribed Creation (遍く示し記す万象, Amaneku Shimeshi Shirusu Banshou?). Avesta is a support-type book Noble Phantasm that records events accurately and correctly out of its own volition. Avenger describes it as being on the level of an automatic typewriter that is useless in a fight due to it being unable to harm anyone, while its only advantage is that it is able to put indescribable emotions and emotions one isn't aware of into words. It was used as the catalyst to summon Angra Mainyu in the Third Holy Grail War, but it instead summoned Avenger, a man who became Angra Mainyu after becoming free from "order" due to having his name removed from the book and having the records of his existence erased.
