The spell that Hermione uses most is either Alohamora or Reparo.
Hermione's bluebell flames
This spell becomes one of Hermione's trademarks. We don't hear the incantation for it in Philosopher's Stone, but it could be a variation on Incendio. Hermione first uses it against Snape when she and Ron think he is cursing Harry's broom in his first Quidditch match.
If there is a spell to encapsulate the asset Hermione is to everyone's favorite magical trio, it has to be Alohomora. Alohomora is, fittingly, the spell that is used to unlock locks. Much like her character throughout the entire series, Hermione is wicked smart, cunning, resourceful, and the best problem-solver.
Evanesco. Evanesco is an extremely interesting and difficult spell to learn and perform. It's a unique transfiguration spell that makes things vanish. Now don't get this confused with an invisibility spell, because this is not an illusion.
Hermione explains that the hourglass is a Time-Turner; she has been using it all year to get to all her classes. Professor McGonagall instructed her to tell no one about it.
What Spell Does Hermione Cast On Her Parents? In Harry Potter and the Deathly Hallows — Part 1, the war with Voldemort (Ralph Finnes) is getting worse, and Hermione casts the spell Obliviate on her parents because she's terrified that he will discover them. This means that they don't remember her or know who she is.
In Deathly Hallows, Hermione faced a real test of her physical and psychological stamina. 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.
Roughly translated, Expelliarmus – the Disarming Charm – means 'to drive out a weapon' and that's what it does: forces the subject to drop whatever they're holding. Usually that's a wand, which is why it's often seen in duels, and Harry definitely took that to heart, given how much he used it in combat.
As the youngest Weasley, we're sure Ginny observed more than her fair share of unpleasant spells over the years but it was the Bat Bogey Hex she was famous for – and with good reason.
But what is the absolute worst of them? Some would say there's no spell worse than Avada Kedavra, the Killing Curse that Voldemort used so indiscriminately.
That said, there are degrees of difficulty when it comes to casting the Unforgivable Curses. The Imperius Curse is presumably the easiest, followed by the Cruciatus Curse, and, finally, Avada Kedavra.
The spell used was Densaugeo. It is a hex which causes the teeth to elongate at a grotesque, alarming rate. The Shrinking Charm can be used to counteract this spell.
It is also likely that she invented the Dumbledore's Army parchment jinx, given the apparent lack of a counter-jinx or cure apart from the boils fading on their own, as well as being specifically stated to identify traitors from the army.
Extended Description. The three curses that are classified as Unforgivable are the Imperius Curse, the Cruciatus Curse, and the Killing Curse. Mad-Eye Moody introduces Harry and his class to these curses in Harry Potter and the Goblet of Fire.
Firestorm. Firestorm was a spell that created a large ring of fire around the caster's wand. This spell is one of the last and most powerful spells that Albus Dumbledore cast using the elder wand before his death.
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. Moaning Myrtle flies off, screaming.
The darkest of the Dark Arts, Harry Potter unforgivable curses are the Cruciatus Curse, the Imperius Curse, and the Killing Curse. Although the curses are highly illegal, Harry using Unforgivable Curses happened, but he uses them once he was thrust into the Second Wizarding War.
The three Unforgivable Curses in Harry Potter are Crucio, Imperio, and Avada Kedavra, and all three are available to Hogwarts Legacy players.
In the book Hermione rescues Sirius with "Alohomora", but in the film, she uses "Bombarda", a spell made up for the films. In the French adaptation of the movie, the spell "Alohomora" is used, instead of Bombarda.
The Deathly Hallows Part I begins with a whole bunch of double-crossing and betrayals. Snape betrays the Order of the Phoenix. A guy from the Ministry of Magic becomes a Death Eater, which is probably how the Ministry ends up falling. And that's just the beginning of the movie.
Her real parents were Daneel and Dean Novak, Pureblooded wizards. Turns out Daneel was Tom Riddles younger sister, Daneel Riddle. Of course, the Riddles were related to Salzar Slytherin himself, and this made Hermione the living heir of Slytherin. The problem with being a female Slytherin heir, is that they're cursed.
Moody's death came at the betrayal of Mundungus, and the moment he disapparated, Moody was struck by a killing curse by Voldemort and fell off his broom to a certain death.
