According to
The plain answer is no. The Killing Curse is illegal, not to mention its use carries the punishment of a life sentence without parole in Azkaban. Someone as shrewd and cunning as Lucius' character, who made sure to get rid of Dark magic items earlier wouldn't have intended to use it on Harry.
“Enraged, Lucius pulls out his wand and begins casting Avada Kedavra before being stopped by Dobby who proclaims 'You shall not harm Harry Potter!
In the movie, yes, Lucius Malfoy did start to say the incantation for the Killing Curse before he got stopped by Dobby. However, Jason Isaacs, the actor playing him, stated in an interview that he just said the first spell that came into his head, which happened to be Avada Kedavra.
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.
It is revealed that The Order of the Phoenix was betrayed by Kreacher, Sirius Black's house elf, when Sirius, in a fit of anger, gave Kreacher an order that permitted him to speak to Sirius' cousin, Narcissa Malfoy.
The main reason is that Lucius failed to retrieve the prophecy from the Ministry of Magic, put that on top of all the other times Lucius failed, and it leads to him losing any clout he once carried within the Death Eaters.
Speak to Sebastian in the Undercroft after this and he'll teach you any Unforgivable Curses you have missed up to that point, including Avada Kedavra. It's worth learning the curse as doing so should have no negative outcome on the game's story.
History Of Avada Kedavra
The Killing Curse was created in the early Middle Ages by Dark witches and wizards. Primarily, the curse was used to quickly slay opponents during a duel.
Quirrell didn't use the Killing Curse on Harry, because Voldemort said “use the boy” to get the Sorcerer's stone from the Mirror of Erised. If Quirrell had killed Harry right away, he would have lost the chance to get the stone.
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.
Mastering Avada Kedavra is a very hard job. The killing curse is one of the hardest of all spells to learn and can only be perfected by very powerful witches and wizards.
Following his failure to obtain an important prophecy at the end of Order of the Phoenix, Lucius is sent to Azkaban for a while until Voldemort breaks him out, although he doesn't play much of a role in the series going forward.
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.
Yes, if the curse is powerful enough. Hagrid is half-giant, and it is said that giant-blood can “absorb” some of the power in spells. ... For instance, Voldemort's Avada Kedavra can probably kill Hagrid with ease. Yes, but it would require a stronger than average wizard casting it to have a killing effect.
Voldemort intentionally made six Horcruxes, but when he used Avada Kedavra on Harry, he unintentionally created a seventh Horcrux. Instead of dying, Lily's love for Harry created a counter 'curse' known as Sacrificial Protection and saved Harry.
Expelliarmus was rendered and painted by Mary GrandPré, who has created the original artwork that appears on the cover of the Harry Potter book series, and at the beginning of each chapter.
Its incantation is Avada Kedavra. The only known counter-spell is sacrificial protection, which uses the magic of love. However, one may dodge the green bolt or block it with a physical barrier.
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.
If you decide against learning Avada Kedavra from Sebastian, that's not the last chance you'll get to learn or use the spell. Once you return to the castle, you can visit Sebastian in the Undercroft in the Defence Against the Dark Arts tower, and ask to learn about it.
Can you still learn Avada Kedavra later? If you decline Sebastian's proposal at the end of the “In the Shadow of the Relic” mission, you can still learn Avada Kedavra.
Hogwarts Legacy's Ranrok Dragon is Technically Not 'Alive'
Players will notice the curse is ineffective if they try to cast Avada Kedavra on it, and not making the final boss a living being is actually a genius way to ensure that players do not anticlimactically fell the dragon in a single hit.
As a result, Voldemort was increasingly dismissive towards Lusicus and his whole family, culminating in the Battle of Hogwarts in Harry Potter and the Deathly Hallows - Part 2, where the Malfoys at long last renounced their allegiance to the Dark Lord and defected to the good side.
Lucius Malfoy's failure at the Department of Mysteries combined with accidentally destroying part of Voldemort's soul with the diary of Tom Riddle resulted in his loss of any standing with the Dark Lord. Some believed that he was safer in Azkaban than being free. Lucius was sentenced to life imprisonment in Azkaban.
If money is power, Lucius Malfoy is the most powerful man in the Wizarding World. Unfortunately, as the later books show us, money is in fact not power and Lucius suffers immensely despite his ludicrous wealth. Lucius ends up such a weak Death Eater, he has his wand stripped from him.
