She didn't say any incantation, but she definitely used 2 spells. The first one froze Bellatrix, most likely petrificus totalus as it looked like what happened to Neville when Hermione used that spell on him. Then for the second spell I guess reducto, as this spell shatters things and blasts them into pieces.
Bellatrix then started taunting Mrs Weasley over her son's death, proceeding to laugh at Molly's enraged response that the Death Eater "will never touch our children again!". This provided an opening for Molly to strike Bellatrix with a curse that hit her straight in the heart, killing her.
Harry became so enamoured with the spell that he eventually used it to finish off Lord Voldemort. Here's how Harry's relationship with Expelliarmus became his signature – and why that's a good and bad thing.
Cruciatus Curse ('Crucio')
Harry tried to use this spell himself. The first time was against Bellatrix after she had killed Sirius.
In the film, Bellatrix casts a blue spell at Ginny Weasley instead of a Killing Curse, who deflects it using a Shield Charm.
After being on the run from a bunch of Snatchers, the gang were taken to Malfoy Manor, where Bellatrix proceeded to torture Hermione using the Cruciatus Curse.
The three Unforgivable Curses are the Cruciatus Curse, which causes unbearable pain; the Imperius Curse, which allows the user to control the actions of the victim; and the Killing Curse, which causes instant death.
Grindelwald refused to tell him, so Voldemort murdered him with the Killing Curse. Grindelwald was responsible for a lot of death when he was raising his army of wizards.
What spell almost killed Draco? In the films, Sectumsempra appears as a small flash of white light which causes a cut when it strikes the target. In LEGO Harry Potter: Years 5-7, Harry uses Sectumsempra on Malfoy only to find out the spell has, apparently, painlessly sliced him in half.
Overview. Avada Kedavra, also known as the Killing Curse, kills a person instantaneously and without injury. There is no countercurse for it, and only one person, Harry Potter, has ever survived it.
When he killed Severus Snape (Alan Rickman) in Harry Potter And The Deathly Hallows Part 2, Voldemort (Ralph Fiennes) used his Horcrux snake Nagini instead of his favorite Unforgivable Curse Avada Kedavra.
When Snape killed Dumbledore. In probably the most shocking twist of the series, Snape cast the unforgivable Avada Kedavra curse on Hogwarts' beloved headmaster.
In order to conjure the avada kedavra curse, you have to want to kill your victim. We all know that Voldemort could easily kill a child without an ounce of remorse... but not Snape. Snape didn't want to kill Dumbledore, and this was why the spell was blue instead of the usual green.
5/10 HARRY CAN'T BEAT: Bellatrix Lestrange Is A Prodigy
Bellatrix is Voldemort's most loyal and most powerful Death Eater of all, and she claimed many victims in Voldemort's name. Fortunately, Voldemort forbade Bellatrix to kill Harry, and then the series' best mom, Molly Weasley, personally vanquished Bellatrix.
No, we don't know what spell did Molly use to take down Bellatrix, but it certainly wasn't Avada Kedavra. Whatever spell she used, it didn't disintegrate Bellatrix either.
Yep, that happened: Bellatrix and Voldemort had sex sometime around Order of the Phoenix or Half-Blood Prince, and their wild night in bed led to a child named Delphi Diggory/Riddle/Lestrange. According to Delphi herself, she was born sometime before the Battle of Hogwarts.
In 1998, Fred participated in the Battle of Hogwarts, defending the castle's passageways with his twin. While fighting alongside his brother, Percy, he was killed in an explosion possibly caused by Death Eater Augustus Rookwood.
Malfoy spots Harry and casts a Cruciatus curse; Harry, defending himself, using the Half-Blood Prince's Sectumsempra spell without knowing its effects. To his horror, it gashes Draco's face and chest, spilling his blood everywhere.
Rictusempra, the Perpetual Tickling charm, which apparently can be stopped by the Finite Incantatem charm, was used by Harry against Malfoy in the Duelling Club. The intent was, of course, to tickle Malfoy to the point that he would be unable to jinx Harry in return.
At the end of Fantastic Beasts 3 though, Grindelwald attempts to use Avada Kedavra on Credence, but Albus and Aberforth Dumbledore successfully block it using golden magic.
Harry Used The Imperius Curse Multiple Times During The Gringotts Heist. Death Eaters had a history of using Imperio to make innocent victims do their bidding.
Confringo. Commonly known as the Blasting Curse, Confringo causes the target to explode. To make it even more dangerous, it produces flames that ignite upon contact with the target. If Confringo fails to kill the target immediately, they will instead suffer a slow and painful death.
Merlin's beard/Merlin's pants
Merlin's beard, Merlin's “baggy y-fronts,” Merlin's pants, or simply just his name are all common curses uttered by the wizarding community in times of surprise or crisis.
