Dumbledore then non-verbally casts a hydro-kinetic spell, where he draws the waters of the Fountain of Magical Brethren so that it erupts and flows out surrounding and encasing Lord Voldemort inside an enchanted sphere of water in an attempt to drown him and finish the duel.
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.
Expelliarmus. Almost beautiful in its simplicity, the Disarming Charm is frequently used in wizarding duels, forcing one's opponent to drop their wand. As soon as a wizard casts this charm by bellowing 'Expelliarmus', a jet of red light shoots from their wand.
He didn't block it. He enchanted a statue to jump in the curses path to be hit instead of the curse hitting Dumbledore. There is no way to block the curse - otherwise countless people could have easily been saved. The Abada Kedavra has no counter, cannot be blocked and is irreversible.
Though Harry encountered many opportunities that deemed Avada Kedavra necessary, it remains as one of the Unforgivable Curses Harry Potter never cast. For one, he viewed the spell as an immoral practice commonly used by users of the Dark Arts.
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.
Therefore, figuring out a spell that is Draco's favorite is hard and, in the movies, there is no defining moment that cements a spell as his favorite. Based on Harry Potter lore, and an article by The Healthy Journal, Draco's signature spell is a N.E.W.T standard spell, The Protean Charm.
Some would say there's no spell worse than Avada Kedavra, the Killing Curse that Voldemort used so indiscriminately. But it's definitely not the wizarding world's only Unforgivable Curse.
Hermione's bluebell flames
Hermione first uses it against Snape when she and Ron think he is cursing Harry's broom in his first Quidditch match. Her bright blue flames set Snape's robes alight, before Hermione scoops them up and puts them into a jar.
Ginny and the Bat Bogey Hex
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.
Avada Kedavra
It's used to kill people, it's an Unforgivable Curse, and it was Voldemort's favourite, so it's going last.
Other Favorite Spells
Plus, there were some votes for Obliviate (erases memory), Silencio (silences someone or something), Homonculus Charm (reveals someone's true identity and location), and Levioso (levitation, and some fans say that this is Ron Weasley's signature spell).
I've always suspected Molly's lethal spell was a particularly well-placed and powerful stunner that stops Bellatrix's heart, which is consistent with the description of her death: Molly's curse soared beneath Bellatrix's outstretched arm and hit her squarely in the chest, directly over her heart.
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.
The spell that Dolohov hit Hermione with was actually purple: But the Death Eater Hermione had just struck dumb made a sudden slashing movement with his wand; a streak of what looked like purple flame passed right across Hermione's chest.
While most fans agree that Harry is the unrefuted Chosen One, the final Deathly Hallows film (in particular) sways heavily toward highlighting a heroic Neville, revitalizing the debate regarding which boy is better suited for the iconic title. "The one with the power to vanquish the Dark Lord approaches ...
Expec - expecto patronum,' said Hermione. Nothing happened. 'It's the only spell she ever has trouble with,' Harry told a bemused Mrs Cattermole.
Snape save Draco by using Vulnera Sanentur spell. Sectumsempra is a curse invented by Professor Severus Snape, during his childhood, when he was known as "The Half-Blood Prince. He created it with intentions of using it against his enemies and it soon became one of his specialties."
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.
In Cursed Child – Part Two, Draco Malfoy explains to Harry that his wife, Astoria Greengrass, was sick for many years. Draco says she suffers from a “blood malediction,” which ultimately ends up killing her the summer before Scorpius's third year.
He truly believed the Elder Wand had to be passed down through murder, because that is what the legends say. But even if he knew that one only had to be disarmed, Voldemort was still too arrogant to do that. He kills anyone in his way.
Sectumsempra is a curse invented by Professor Severus Snape, during his childhood, when he was known as "The Half-Blood Prince". He created it with the intention of using it against his enemies, and it soon became one of his specialties.
Severus Snape is one of the most divisive characters in the entire "Harry Potter" series. He was a double agent, so many character details were kept a secret. His mother was a witch and his father was a Muggle, leading to the moniker "The Half-Blood Prince."
