Casseur de Logistille: Destruction Declaration (破却宣言, Hakyaku Sengen?) 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 Luna Break Manual: Magical All-purpose Tome of Tactics (魔術万能攻略書, Majutsu Ban'nō Kōryaku-sho?) 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. When its True Name is released and the book is read, it becomes possible to break all magecraft close to High-Thaumaturgy 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.

Therefore, it is able to phase through every single attack.
Declaration of Complete Destruction [Noble Phantasm]
Casa Di Logistilla. One of the cheat Noble Phantasm of Rider of Black, Astolfo. A witch specially gave it to Astolfo after being charmed by him. This book, containing written within it the means to destroy all spells, can grant A rank Magic Resistance just by possessing it.
Not only that, if its true name is invoked—in other words, if the book is read, one can drag out the possibility of destroying any spell. It could perhaps be called a form of “Eye of the Mind” limited to magecraft. It is the Noble Phantasm that represents the cheat-ness of Astolfo.
Because Astolfo irresponsibly called it by the name “Luna Break Manual”, its true power invoked by its true name didn’t appear until volume 5. Even leaving that aside, it is such an outrageous Noble Phantasm that, if someone like the Witch of Colchis knew about it, she would put him on her list of people to immediately kill at the earliest opportunity.
