HARRY POTTER WAND SPELLS: (revamp.) 1 of ?

A spell is a magical action often accompanied by an incantation that makes use of the magical force of the wizarding world in order to accomplish extraordinary feats ordinary people (Muggles) cannot perform. Spells often have some kind of physical representation in the form of light and as such can usually miss, be dodged, or blocked with an object (including another spell). The action of performing a spell is referred to as casting or spellwork.
