======Challenges in Charming======
=====Book Information=====

  * **Difficulty Level:** Advanced, suitable for study at [[N.E.W.T.]]-level.
=====Description and Content=====
//Challenges in Charming// is an advanced textbook on the subject of [[Charms]]. Its physical appearance is not described in the original novels. As its title suggests, the book focuses on particularly complex and difficult-to-master [[Charms]] that go beyond the standard curriculum for [[O.W.L.]]-level students at [[Hogwarts School of Witchcraft and wizardry]].
The book serves as a reference for advanced magical theory and practical spell-casting for some of the most intricate [[Charms]] known. The most significant piece of magic known to be detailed within its pages is the [[Protean Charm]], a highly complex spell that links the appearance of several objects so that a change to one will be reflected on the others. The inclusion of such a spell indicates that the text covers magic that is considered exceptionally difficult by wizarding standards.
=====Role in the Story=====
The book's primary significance in the series occurs in //Harry Potter and the Order of the Phoenix//. After founding [[Dumbledore's Army]], [[Hermione Granger]] devises a secret method of communication for the group's members. She gives each member a fake [[Galleon]] and, using information she learned from //Challenges in Charming//, places a [[Protean Charm]] upon them.
When [[Harry Potter]] set the time for the next meeting, he would alter the numbers on his coin, and the other coins would instantly change to match. [[Hermione]] explains that the [[Protean Charm]] is `[[N.E.W.T.]]`-level magic, highlighting the advanced nature of the book's content. Her successful casting of the spell greatly impresses fellow student [[Terry Boot]], who notes that it is a very difficult piece of magic. [[Hermione]] explicitly credits her success to having read about it in //Challenges in Charming//. This communication method was inspired by [[Lord Voldemort]]'s use of the [[Dark Mark]] to summon his [[Death Eater]]s, but served a more noble purpose for the [[D.A.]]
