40 Most Powerful Harry Potter Spells and Curses, Ranked

The Wizarding World captures the imagination of fans old and new, creating a sense of belonging and making Hogwarts feel like a second home. The films beautifully bring J.K. Rowling’s books to life, sharing the magic with audiences everywhere. Within this world, a diverse cast of wizards and witches wield a variety of spells, with varying degrees of power.

Spells in the wizarding world come in many forms – from simple charms to powerful curses. Skilled witches and wizards can use them as formidable weapons. While many spells are associated with dark magic and used by villains, others appear harmless but can have surprising effects. The Harry Potter books feature hundreds of different spells, and though not all are equally strong, a few stand out for their incredible power.

Accio Is More Powerful Than People Think

The summoning charm, Accio, is more than just a simple spell – it’s incredibly useful and strong. Harry Potter actually relied on Accio to succeed in the first Triwizard Tournament task. It allows a wizard to instantly summon any object directly to them. For instance, Harry used it to grab his broom during the tournament and retrieve the dragon egg. Even more crucially, he used Accio in the graveyard to summon the Portkey and escape Lord Voldemort.

Most wizards use the Accio charm for everyday tasks – like summoning a drink, a book, or anything else they need without having to move. But it can also be a lifesaver or help retrieve something important that’s out of reach. Being able to instantly have an object in your hand is useful both in daily life and during a fight. Harry Potter, for instance, frequently used Accio to summon his glasses, as he needed them to see.

Alohamora Can Open Most Doors

Alohomora is a simple yet incredibly helpful spell, even first-year students like Hermione Granger could master it. It allows witches and wizards to unlock any lock that isn’t magically protected, and can often get someone out of a difficult situation.

Throughout the Harry Potter series, Harry and his friends frequently rely on the Unlocking Charm. Hermione first uses it during her first year to unlock a castle door and avoid Mr. Filch, and later in her third year to free Sirius Black from Professor Flitwick’s office. While not effective in combat, the charm is crucial for escaping danger and rescuing others, which is just as important as fighting.

Tarantallegra Can Be Used to Force Anything With Legs to Dance

Tarantallegra causes the legs of anyone hit by it to move uncontrollably. It’s generally a harmless spell used for jokes, but it can be surprisingly effective in a duel because it makes it hard for the target to stay on their feet. This could be really helpful for preventing a wizard from escaping, as they wouldn’t be able to run.

The Tarantallegra spell isn’t limited to people; wizards can even make objects like chairs move. While usually harmless if cast carefully, it can be dangerous. A particularly disastrous instance occurred when Zaccaria Innocenti used the spell on Mount Vesuvius, triggering an eruption and causing a massive loss of life. More commonly, it’s used for lighter purposes – Dumbledore famously made the castle’s suits of armor dance with it.

Rictusempra Provokes Uncontrollable Laughter, But It’s Not Funny

Rictusempra is a basic defensive spell often taught to students. It forces the person hit with it to laugh uncontrollably, and while it may seem harmless, it’s actually quite powerful. Constant laughter prevents a wizard from casting spells, effectively removing them from a fight.

Rictusempra could be a surprisingly cruel form of torture. While Crucio inflicts intense pain, being forced to laugh uncontrollably for hours could be just as frightening. Since Rictusempra isn’t illegal like Crucio, it’s unsettling to think about the terrible ways dark wizards might have used it.

Morsmordre Has the Power to Cause Horror

Essentially, this creates a massive image of Lord Voldemort’s symbol, the Dark Mark, in the sky. Though a moving skull with a snake is frightening, it’s harmless on its own. The true power of the Dark Mark comes from the fear it instills in people.

During the time Voldemort was in power, his followers, the Death Eaters, would summon the Dark Mark at the scenes of their crimes, signaling a murder. When Harry attended the Quidditch Tournament, Barty Crouch Jr. conjured the mark, causing widespread panic and injury among the wizards camping nearby. Even though Voldemort is gone, seeing the Dark Mark appear in the sky would almost certainly cause chaos and fear.

Locomotor Mortis Has a Few Important Defense Uses

As a film buff, I’ve always thought the Leg-Locker Curse – or Locomotor Mortis – is a neat trick for escaping a chase. It basically freezes someone’s legs, giving you a bit of breathing room. However, it’s not a perfect defense; their arms are still free to, you know, attack! It can buy you a few crucial seconds, but everyone knows the counter-curse, which Hermione actually used to help Neville after Draco used it on him. Honestly, when you stack it up against other spells we see, it’s not nearly as powerful or impressive.

Diffindo Creates a Deep Cut Through Its Target

The Diffindo charm is a spell used for cutting things. While it’s generally meant for objects, it can be used on people, so Hogwarts teachers always remind students to be careful with their wand movements to avoid accidental injuries. Interestingly, in the game Hogwarts Legacy, Diffindo is a very powerful spell for fighting dark creatures and wizards.

Diffindo is a basic spell taught to Hogwarts students early on, and it can be helpful for wizards who are new to dueling. While it’s not a common attack seen in battles alongside spells like Stupefy or Expelliarmus, it’s still effective, as demonstrated in Hogwarts Legacy. The Severing Charm is also practical for escaping tricky situations, like cutting ropes or anything that’s tying you up.

Impedimenta Can Reduce the Moving Velocity of a Target

The Impediment Jinx was a widely used spell in duels, mainly because it didn’t cause any permanent harm. When cast, it creates a force that either slows an opponent down or stops them from moving. It was even taught at the Hogwarts Dueling Club, meaning most witches and wizards with a magical education would know how to perform it.

Hermione first showed Harry how to perform the Impediment Jinx, which he then taught to the members of Dumbledore’s Army. Interestingly, James Potter also used this spell against Snape during a bullying incident Harry witnessed in a memory. While good for practice duels, the Impediment Jinx isn’t very effective in serious magical fights.

Depulso Is Versatile But Doesn’t Cause Much Harm

Depulso is essentially the reverse of the Accio charm. Where Accio pulls things towards you, Depulso pushes them away – whether it’s an object or a person. In a magical duel, it can be used to create distance between you and your opponent, potentially causing them to stumble and giving you a moment to react, all without causing serious injury.

Although it’s a powerful spell for one-on-one magical duels, it isn’t often used in actual battles throughout the Harry Potter books. Students learn the spell in their fourth year at Hogwarts, and Neville Longbottom famously miscasts it, sending Professor Flitwick flying. It does appear once, however, when Severus Snape uses it against Dolores Umbridge in the play Harry Potter and the Cursed Child. Additionally, the spell plays a crucial role in some fan fiction.

Levicorpus Dangles the Opponent Upside Down

The Dangling Jinx is a spell Severus Snape invented when he was a student at Hogwarts. Harry discovers it while looking through Snape’s old Potions textbooks and decides to attempt it. The spell’s incantation is ‘Levicorpus,’ but Snape originally designed it to be cast without speaking. There’s a straightforward counter-spell – ‘Liberacorpus’ – though it isn’t widely known.

This spell lifts a person up by one foot, suspending them in the air. While it might not sound dangerous, it’s surprisingly effective in a fight, as it makes it hard for the opponent to attack or pursue the caster. Interestingly, Hermione once used this spell to lift Harry while they were in Gringotts, allowing him to reach for the Hufflepuff Cup Horcrux, demonstrating its versatility. Even Lord Voldemort employed it, using it against the wandmaker Gregorovitch.
