Stupefy

Probably one of the most famous spells in Harry Potter and the Order of the Phoenix, Stupefy is a spell, and is used to stun your opponent. When casted correctly, a jet of red light should come out of your wand and hit the opponent, to show the most affect, squarely in the chest. This spell will knock your your opponent out for a particular amount of time, depending on how accurate your cast is and where it hits the opponent. A completely accurate stunning spell can knock the opponent out for hours on end. Stupefy is also very affective when used by more than one wand at the same time, and can cause serious damage or injury to your opposition when at it's most powerful.

Rating
5/8-Stupefy is a spell that you will learn around your fourth or fifth year at Hogwarts School. It is quite hard to learn, but easy once you perfect it and cast it properly.

The Order of the Phoenix
Stupefy is probably used most commonly in the fifth of the Harry Potter series, with both good and bad results. Harry and his many friends from Dumbledore's Army (D.A) learn the spell so they can be ready to fight Voldemort and his followers, because Professor Umbridge refuses to teach them any defensive spells or magic. Stupefy is used for the first serious time on the head of Gryffindor house, Professor McGonagall when she tries to save Rubeus Hagrid, Hogwarts Gamekeeper and teacher of Care for Magical Creatures from being taken away by Umbridge along with Draco Malfoy and the rest of the Inquisatorial Squad. The spell is also used in the Department of Mysteries several times by Harry and his friends Ron, Hermione, Luna, Ginny, and Neville on Voldemort's Death Eaters in the battle for the prophecy containing important information about Harry and Voldemort.

Learning
Stupefy can be considered as a hard spell to learn, but is actually very easy once you perfect it. When learning Stupefy, the stunning spell, wave your wand in the direction of an up-side down triangle and say clearly and loudly: Stupefy! If correct and accurate, the red jet of light should shoot directly from the end of your wand and hit the opponent. this video shows Harry Potter defeating Dean Thomas in a duel using Stupefy and stunning him.

Appearance
There is usually one main colour in a correctly cast stunning spell; red. When cast, the spell will travel a little slower than average at the opponent. Stupefy also has two or three smaller red spirals swirling in and out and around of the main cast, making it more powerful. When a correct stunning spell hits your opponent, it will normally stop and not make an extra blast of light, however, when stupefy is cast correctly and most accurate, it may produce smaller blasts or sparks while travelling towards the opponent.
