Originally Answered: Can Albus dumbledore look through the invisibility cloak? No, he couldn't.
Additionally, in Harry Potter and the Chamber of Secrets, Professor Dumbledore looks right at Harry and Ron underneath the Invisibility Cloak while in Hagrid's hut, suggesting that Dumbledore might actually be able to see through the Invisibility Cloak.
(More technically, Barty Crouch Jr.) The Invisibility Cloak of the Deathly Hallows is supposed to be unlike other cloaks, which can be detected through alternative means. But, in Goblet of Fire, Barty Crouch - disguised as Mad-Eye Moody - steals Polyjuice ingredients and sees Harry while he's wearing the cloak.
The subsequent sacrificial protection put on Harry, shielding him from harm, was a form of ancient magic. Both Albus Dumbledore and Voldemort were aware of this ancient magic, and Voldemort was known to "despise" it.
@AlexChan: however it is established that Snape must have learnt about the cloak for sure by the time of GOF ( 'Potter! ' Snape snarled, and he actually turned his head and stared right at the place where Harry was, as though he could suddenly see him.
Basically. Voldemort thought Snape was a death eater spy pretending to be a order spy; Dumbledore knew Snape was a order spy pretending to be a death eater spy who was pretending to be a order spy.
These wizards can see invisible creatures. Sound familiar? Dumbledore knew Harry and Ron were under the invisibility cloak at Hagrid's hut in Harry Potter and the Chamber of Secrets, as his eyes flickered in their direction.
In Rowling's Harry Potter series, Dumbledore demonstrated the ability to possess wandless magic on several occasions, most memorably when he cast Aresto Momentum without a wand to save Harry from falling to his death during a Quidditch match.
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.
If, by unfortunate means, Muggles do happen to observe the working of magic, the Ministry of Magic sends Obliviators to cast Memory Charms upon them, causing them to forget the event. Some Muggles are aware of the wizarding world.
At different points, Dumbledore possessed all three Deathly Hallows. He won the Elder Wand from Grindelwald, had the Invisibility Cloak in his possession when James Potter died, and wore the Resurrection Stone as it sat in Marvolo Gaunt's ring. Dumbledore's powers are really quite extraordinary!
The three Deathly Hallows – the Invisibility Cloak, the Resurrection Stone and the Elder Wand – have tempted many a wizard over the years.
When Draco attacked Harry in the train in Half-Blood Prince, why he didn't take the invisibility cloak? Draco wanted Harry to remain undetected as long as possible, so he left the invisibility cloak. Besides, if Draco had taken it, then once Harry was found, he would have immediately reported the theft of his cloak.
As J.K Rowling revealed, Albus Dumbledore had mastered Parseltongue too – although he could not speak it aloud. We're not sure why Albus learnt the language, but perhaps the Hogwarts headmaster wanted a better understanding of Voldemort.
Albus Dumbledore is the most obvious person who can defeat Voldemort, and the Dark Lord seemed to realize it. Rowling herself has explicitly stated in the books that Dumbledore is the only person Voldemort fears and recognizes as a genuine threat to his own power.
Because in Fantastic Beasts he is still a young man, late 30's - early40's, while in Harry Potter he's in his golden years, either 108 or 110. So it's kind of like asking a 90 year old who walks around in PJ's and a robe why he no longer wears the suits that he wore in his younger years.
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.
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.
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.
It's made explicitly clear that Hermione Granger is an exceptional witch with abilities far beyond her age. It's no surprise, then, to see her performing wandless magic in high school. Her wandless magic can be seen prominently in The Half-Blood Prince.
He could have easily defeated Malfoy outright when he showed up, or even after losing his wand. But that wasn't the plan. He needed Malfoy to get the wand so Harry could take it from him. It would have been convenient for Malfoy to kill him, too, but he know Malfoy wasn't brave enough for such an act.
No, Dumbledore's dark secret was never that he had aided Grindlewald or sought the Deathly Hallows, although he expressed regret for both of these things years later. The secret he swore to keep hidden, out of shame and remorse, was that he had taken part in his sister Ariana's death.
He has grown afraid of Harry's connection to Voldemort. Perhaps Voldemort, knowing Dumbledore's love for Harry, would possess Harry and provoke Dumbledore to kill him. So, Dumbledore attempted to avoid Harry throughout Book 5 for Harry's own good.
During their very first conversation in Harry Potter and the Sorcerer's Stone, Dumbledore tells Harry that he sees himself holding a pair of thick, woolen socks when he looks in the Mirror of Erised.
