A Wand is a quasi-sentient magic instrument through which a witch or wizard channels his or her magical powers, and thereby centralizing the effects for more complex results. Most spells are done with the aid of wands, but it is possible to do spells without the use of wands. Wandless magic is, however, very difficult and requires much concentration and incredible skill; only truly advanced wizards are known to perform such magic.

In addition, magic with a wand is mostly performed with an incantation, but Nonverbal spells are also possible for more experienced wizards and are a great deal more helpful in dueling, as the opponent has no way of knowing what spell you are going to cast and thus might not be able to adequately protect him or herself in time. Wands are referred to as "quasi-sentient" because they are as close to animate as an inanimate object can get. This is because they are imbued with a great deal of magic.

Wands are manufactured and sold by Wandmakers, and each wand is made of a specific type of wood with a magical substance making up the core. Although the wand cores may come from the same creature, or the wood may come from the same tree, no two existing wands are exactly alike. The study of the history and the magical properties of wands is called Wandlore.
