Type: Charm
Pronunciation: STOO-puh-fye
Description: Stuns the target, rendering them unconscious.
Seen/Mentioned: Often; particularly by a number of wizards and witches (including Dolores Umbridge) against Minerva McGonagall in 1996. It's also taught by Harry in his D.A. meetings.
Etymology: English stupefy, which means 'to put into a stupor', a temporary vegetative state.
Notes: The physical manifestation of the spell is a beam of red light emanating from the caster's wand. The spell wears off after a short time, and can be countered by Rennervate. Nearly useless on magic-resistant creatures such as dragons, trolls and giants unless more than one Stupefy spell is used at the same time. The force of the spell is additive or perhaps even exponential, and it can cause severe injury if many spells are used on a target that is not normally resistant to its effects. Hagrid, as a half-giant, is impervious to this spell - or at least, a lone one.
