The Dark Arts Outsmarted is a book about defensive magic. This book is one of the hundreds of books that the Room of Requirement supplied for Dumbledore's Army in their first gathering there. Seeing this and other such books helped convince Hermione Granger that she and the others were doing the right thing by participating in the group.
