Stunning Spell




Hand Movement

Point wand at target




Renders a victim unconscious

"The jet of red light hit the Death Eater in the middle of his chest: he froze, his arm still raised, his wand fell to the floor with a clatter and he collapsed backwards towards the bell jar."

The Stunning Spell (Stupefy), also known as a Stunner or Stupefying Charm[1] is a charm[2] that renders a victim unconscious and halts moving objects. It is commonly used in duels, and was one of the spells Harry Potter taught Dumbledore's Army. If the spell is used by multiple wizards aiming at the same target, the damage it causes is increased, for example; Professor McGonagall had to be moved to St Mungo's after being hit with the spell by multiple Ministry of Magic employees in 1996, and Madam Pomfrey expressed surprise that it did not kill her. If multiple Stunning Spells are aimed at a dragon, they will work, however one alone is not strong enough.[3] It manifests itself as a jet of scarlet light.

Defence against the Stunning Spell[edit | edit source]

The effects of a Stunning Spell may be counteracted by Rennervate, but will also wear off with time. It can also be deflected by a Shield Charm. Species known to be naturally resistant to the spell include dragons, trolls, giants and half-giants. Rubeus Hagrid was unaffected by this spell when, in 1996, several Ministry of Magic employees attempted to remove him from Hogwarts grounds.

It is also possible to bewitch objects to be resistant to the spell. Fred and George Weasley bewitched their fireworks to explode when hit by Stunning Spells.[3]
