Severus Snape, as the "Half-Blood Prince," created several powerful and infamous spells, most notably Sectumsempra (deep cuts), Levicorpus (hangs victims upside down), Muffliato (fills ears with buzzing), Langlock (glues tongue to roof of mouth), Liberacorpus (counter to Levicorpus), and the Toenail-Growing Hex, with some sources suggesting a total of seven significant creations, including the Laceration Curse (often synonymous with Sectumsempra).
He also made notes in the margins of several spells that he had invented himself, including Sectumsempra, Levicorpus, Langlock, and Muffliato. When Severus left Hogwarts, he fell in league with the Death Eaters, though he never lost his old copy of Advanced Potion-Making.
Overview. Sectumsempra is a very dark curse that causes a cut (Latin "sectum" = "cut") which will not heal ever (Latin "semper" = "always").
Liberacorpus was the incantation for the counter-jinx to the Dangling Jinx (Levicorpus).
With James Potter the spell Snape used just left a nasty gash on the side of James' face, but other than that it didn't keep cutting into his face. So it makes sense that Snape's spell was most likely a prototype of Sectumsempra and Harry just used the final spell properly, not more or less than it was intended.
Page 394 in Harry Potter and the Prisoner of Azkaban refers to Professor Snape's famous line, "Turn to page 394," which directs the Defense Against the Dark Arts class to werewolves, as he tries to reveal Professor Lupin's secret, although the specific content (werewolves) appears just before the climax in the Shrieking Shack scene in the actual book text.
It's not a common spell. Snape made it up. It was most definitely not Ministry approved. Because it isn't part of the 3 Unforgivable Curses.
Meteolojinx Recanto is used to stop or reverse these weather-altering spells and restore the natural weather conditions. It's mentioned by Arthur Weasley in Harry Potter and the Deathly Hallows, who is referring to the constant raining within certain Ministry of Magic offices.
Protego Maxima is a stronger version of the Shield Charm that, when cast in combination with Fianto Duri and Repello Inimicum, conjures up an almost impregnable magical protection barrier.
In Harry Potter, the "Three D's" are the essential principles for successful Apparition (magical teleportation): Destination, Determination, and Deliberation, taught by Ministry instructor Wilkie Twycross to avoid "splinching" (leaving body parts behind). You must firmly visualize your Destination, have the unwavering Determination to reach it, and then move with focused Deliberation, without haste, to arrive safely, notes the Harry Potter Wiki and Harry Potter Lexicon.
The injury was caused by Snape's Sectumsempra spell in order to stop the Death Eaters from hurting George (who he thought was Harry) and Lupin, but missed and hit George. Hermione and Kingsley then arrived, both unharmed, followed by Arthur and Fred Weasley, both concerned for George.
When Harry critically injured Draco Malfoy with the Sectumsempra curse, it was actually enough to have him expelled, as Professor Minerva McGonagall stated Harry was lucky not to have been, due to Snape giving lenience to prevent others from finding out that he was the one who invented the curse.
Defodio is a burrowing charm. Its primary function is to excavate or dig into materials, essentially allowing the caster to create holes or trenches. Think of it as the wizarding equivalent of a mini-bulldozer, but way cooler and with more incantations.
Accessed through an abandoned red telephone box the Ministry can be reached by dialling 62442 (which spells 'MAGIC' on an alphanumeric keypad).
He was knowledgable with the Dark Arts as well as many forms of magic, being the only Death Eater to be able to fly without a broom like his Master. Still, Snape could never beat Voldemort. The Dark Lord was a prodigy himself, and his level of skill in Dark Arts was unmatched.
The Dark Mark could also be cast into the sky using the spell Morsmordre, signifying a murder had taken place or a heinous attack. A famous usage of this happened during the Quidditch World Cup, when Death Eaters invaded the campsite where the event was held.
In this game, casting Protego Diabolica causes a ring of blue fire to erupt around the player character, damaging all enemies inside the circle whilst three successive waves of flaming dragons are launched at the opponent.
Fianto Duri was the incantation of a charm that, when combined with a protective spell such as Protego Maxima, could cause magical defences to become hard or more durable.
The Severing Charm (Diffindo)
The Severing Charm allows the caster to cut or tear through an object using the incantation Diffindo. Whilst it is not an easy spell, it is one that Hogwarts students should be able to perform. Harry once used this Charm to cut through Cedric Diggory's bag when he wished to talk to him.

They are the Killing Curse, Imperius Curse and the Cruciatus Curse. The use of any one of these spells is enough to land a witch or wizard a one-way ticket to Azkaban.
Harry never used the Killing Curse, Avada Kedavra, due to his moral stance against murder and his personal connection to its victims.
In the Deathly Hallows part 2, Ron Weasley performs the Imperius curse on Bogrod, the goblin teller. [11] Deathly Hallows pt. 2 / During the scene where the trio break into Gringotts, Ron Weasley effortlessly uses the Imperius Curse on Bogrod, the goblin teller, without hesitation.
