The '''wand''' of [[Cho Chang]] is of unknown length, [[wand wood|wood]], and [[wand core|core]]. Like most [[Wizards|wizards and witches]] in [[Great Britain]], she likely purchased it at the age of eleven from [[Garrick Ollivander]] before beginning her education at [[Hogwarts School of Witchcraft and Wizardry]] in [[1990]]. She performed a wide range of powerful magic with the wand, from [[Charms (class)|charms]] to [[Defence Against the Dark Arts|defence]]. During her training with [[Dumbledore's Army]], Cho also learned to produce a fully corporeal [[Patronus]], a feat which [[Remus Lupin]] mentioned to be quite impressive for young wizards.
