Casseur de Logistille

is a thick magic-binding leather book specially given by and inherited from a witch, Logistilla, to Astolfo, after the former was charmed by the latter. It contains records of the means to shatter any magecraft, granting its owner the passive ability to deal with magecraft of A Rank and below. Though his Magic Resistance is normally D Rank, it is greatly elevated to A Rank, effectively making him immune to all modern magecraft.
At the start of the Great Holy Grail War, he forgets its True Name, granting it the "suitably attached name" of until he later is able to remember its real name by recognizing the moon is not in the sky. It is related to the legend of how Astolfo found his reason on the moon. Whenever the moon is visible to Astolfo, he would have no reason for it would be on the moon. On the other hand, should the moon not be visible, Astolfo regains his reason, thus remembering this Noble Phantasm's True Name.Fate/Apocrypha - Volume 5: "空に輝く月はない。

「さあ、行くよ--マスター--」" When its True Name is released and the book is read, it becomes possible to break all magecraft close to greater magecraft excluding Reality Marbles. It could perhaps be called a form of "Eye of the Mind" limited to magecraft.
Astolfo can also use Casseur de Logistille as a Saber, with it functioning as a Skill in Fate/Grand Order. It eventually upgrades to Casseur de Logistille (Strong).
