After Credence defies him, and he is outed for faking the Qillin election, Grindelwald retaliates by aiming Avada Kedavra at Credence in retaliation. Grindelwald tells his acolytes to use the curse during Crimes of Grindelwald.
How did Dumbledore block Avada Kedavra from Grindelwald?
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.
The Headmaster's brilliance is practically limitless; more importantly, there are brands of magic that he would never resort to, regardless of the situation. He could have theoretically defeated Voldemort with a simple Avada Kedavra, but he chooses to err on the side of compassion, instead.
A newer spell that appears in The Crimes of Grindelwald, Protego Diabolica summons a circle of flame around its caster, keeping all allies safe and incinerating opponents. In the script, Protego Diabolica is described as black, but the movies portray it as light blue spell.
The Harry Potter wiki describes this spell as an “incantation to a protective spell, a modified version of the Shield Charm. Protego Diabolica conjures a protective ring of fire around the caster.”
Originally Answered: Who is actually more powerful between Severus Snape and Gellert Grindelwald? Grindelwald. Grindelwald is renowned on the same level as Dumbledore and Voldemort. And while Snape is powerful, he is nowhere close to Grindelwald.
Effect. Unforgivable Curses are the three most powerful and sinister spells known to the wizarding world, and are tools of the Dark Arts. They were first classified as "Unforgivable" in 1717. They are the Killing Curse, Avada Kedavra, the Cruciatus Curse, Crucio, and the Imperius Curse, Imperio.
The intent of the caster is a vital component of the spell. While Snape was still able to produce Avada Kedavra without any intent to kill, being a great wizard, the mix of hesitation and necessity probably resulted in the spell being blue.
Simple answer is, that's only in the movies. They often play fast and loose with things that might look or sound cool in the moment but make no sense in the overarching story. Ron never casts Avada Kedavra at Nagini in the books.
The Killing Curse, as an "unblockable" Curse, cannot be intercepted by another spell, except in circumstances of Priori Incantatem, where the caster and his opponent's wands and spells are locked together. An explosion or green fire may result if the spell hits something other than a living target.
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. In 1707, the Wizards' Council was restructured into the Ministry of Magic, which allowed for more strict restrictions on certain types of magic.
In the final movie, Harry Potter and the Deathly Hallows pt. 2, Molly first hits Bella with a spell that freezes her, most likely Petrificus Totalus. Then, she launches another one that shatters her entire body into pieces, which could be expelliarmus, bombarda, stupefy, or any spell that can produce such an effect.
The Disarming Charm became Harry Potter's signature spell, and it notably caused the final defeat of Lord Voldemort during the Battle of Hogwarts by rebounding his Killing Curse, because the Elder Wand recognised Harry as its master through the spell connection, and thus strengthened the Disarming Charm to the point ...
Nevertheless, while the impact of Avada Kedavra was unforgettable, Crucio was far more deadly than that, and Imperio as it could make a victim beg for death solely to stop the pain.
The author explicitly states that both women were fighting to kill, despite Molly refraining from casting the Unforgivable curse Avada Kedavra. The result of the duel actually comes about as a result of nothing more than spectacular accuracy on Weasley's part.
After the Wizards' Council was reformed into the Ministry of Magic, tighter restrictions were placed on the use of certain kinds of magic. The Imperius Curse was deemed by the Ministry to be Dark magic, and, along with the Cruciatus and Killing Curses, were declared "unforgivable" in 1717.
Harry used the Imperius Curse multiple times during the Gringotts heist to accomplish their mission. Harry never used the Killing Curse, Avada Kedavra, due to his moral stance against murder and his personal connection to its victims.
Death. Fifty-three years after his defeat, Grindelwald was slain in his prison cell by Lord Voldemort, who was searching for the Elder Wand for himself. It was only during the confrontation in Grindelwald's cell that Voldemort learned Albus Dumbledore had claimed the wand long ago.
When it comes to the area of Transfiguration, McGonagall definitely has the upper hand. But when it comes to inventing spells, the Dark Arts, Legilimency and Occlumency, Snape has the edge. McGonagall is surprisingly skilled in the Dark Arts but not on the same level as Snape.
How much did McGonagall know about Snape? Dumbledore and Snape formed an alliance not to tell ANYONE about protecting the boy as it would put his protection in danger. Thus, it cannot be that McGonagall knew about Snape. As for the relationship of Lily and Snape, most teachers knew about that.
