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.
The disarming spell would have specifically taken away Voldemort's powerful wand. Even if he were to use a Death Eater's wand after that, it wouldn't be the Elder Wand. Also, the time between disarming & rearming Voldemort could be used to decisively defeat Voldemort.
Avada Kedavra is illegal. Aurors needed explicit authorization in the First Wizarding War to use the three Unforgivable Curses. They are "moral". They don't wish to kill.
Harry makes use of two of the Unforgivable Curses in the books. Dueling with Bellatrix Lestrange, he attempts the Cruciatus curse, with limited results; Bellatrix says that he has to really hate someone to make the Unforgivable Curses work properly, righteous indignation isn't enough.
Alohomora, which is a spell that unlocks objects (and it's also Hermine Granger's signature spell).
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.
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.
Hogwarts Legacy's Ranrok Dragon is Technically Not 'Alive'
Ranrok absorbs this swirling crimson substance and becomes the Ranrok Dragon that players then fight as Hogwarts Legacy's final boss, but because it is composed of magic and adorned in what looks like metal or stone, Avada Kedavra is not effective on it at all.
Avada Kedavra
Topping the list for the most powerful spells in the Harry Potter universe is no other than Avada Kedavra, Voldemort's favorite to instill his will and fear onto others. The spell itself is a play on Abra Kadabra and is easy to cast by just about anyone in the Wizarding World.
Her sacrifice gave Harry the power of love, a protection spell sealed with the blood spilled by her death.
At the beginning of this book, he measures it against Lucius Malfoy's showing he still has it and it is intact. Dumbledore explains to Harry in book 4 that since both wands contained a tail feather from Fawkes the phoenix, the couldn't face each other as they'd refuse to destroy each other pretty much.
7 Draco Malfoy: The Protean Charm.
Riddikulus
Riddikulus is the spell that's used when facing a Boggart, and it's used to turn the Boggart into something that the caster finds funny.
Avada Kedavra
It's used to kill people, it's an Unforgivable Curse, and it was Voldemort's favourite, so it's going last.
Unfortunately, while you'll be able to use it in the arena, you won't have access to it anywhere else. So if you are looking for another chance to learn Avada Kedavra in Hogwarts Legacy, you can't really, but you can use it for a while at the Dark Arts Battle Arena.
In Harry Potter lore, the Avada Kedavra is accompanied by a blinding flash or jet of green light, and can only be countered by sacrificial protection, which used the power of love. But that's not going to do you much luck in Hogwarts Legacy.
Who is immune to Avada Kedavra? Phoenixes were semi-protected from the Killing Curse, due to them being immortal. In 1996, Fawkes swallowed one intended for Albus Dumbledore, causing him to burst into flame and die instantly. However, he then was reborn from his ashes.
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.
Erroneously believing Snape is the master of the Elder Wand and that Snape's death will make him the master of the Wand, Voldemort kills Snape by having his pet snake Nagini bite him through the neck.
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.
Hermione Granger
Her wandless magic can be seen prominently in The Half-Blood Prince. She performs Confundus on Cormac McLaggen simply by whispering into her hand. She also successfully performs Avis and Oppugno Jinx without the use of her wand when sending birds to attack Ron.
What Is Dumbledore signature spell? There were two; Apparation and Invisibility. Dumbledore must have used these particular skills thousands of time in his lifetime for any number of purposes. His vast gathering of knowledge probably came as a result of his skill in appearing and disappearing at will and unseen.
