As a longtime fan, I’ve always felt the Harry Potter films did an incredible job bringing J.K. Rowling’s wizarding world to life. For so many of us, these movies are how we experienced Harry’s story, from his humble beginnings to his ultimate showdown with Voldemort. But let’s be real – squeezing seven huge books into eight films meant a lot had to be cut. While the movies were fantastic, they just didn’t have the room to explore every nook and cranny of Rowling’s world. That’s why I’m so excited about the new HBO series – it feels like a chance to finally see those lost details and storylines brought to the screen. The films gave us the broad strokes, but this series promises a deeper, more complete experience.
Fans of the Harry Potter books will remember many brilliant and strong spells that weren’t included in the movies. Although the films featured a lot of impressive magic – from basic spells like Disarming Charm to the dangerous Unforgivable Curses – some of the most imaginative and important spells only appeared in the books.
5) Waddiwasi

Remus Lupin knew many spells, but Waddiwasi is one of the most unusual. It’s a charm that forcefully launches small objects with great accuracy. We only see it used once in the books, in Harry Potter and the Prisoner of Azkaban, when Lupin uses it to stop a prank by the mischievous ghost, Peeves. Peeves had blocked a keyhole with chewing gum, and Lupin calmly cast Waddiwasi, instantly shooting the gum up Peeves’ nose. Though it seems like a small spell – Lupin calls it “useful” – Waddiwasi can quickly turn everyday objects into projectiles.
4) The Fernunculus Curse

The Furnunculus Curse causes painful, unsightly boils to erupt on the victim’s skin. Harry Potter first tries to use this curse during a duel with Draco Malfoy in Harry Potter and the Goblet of Fire, but accidentally hits Gregory Goyle instead, giving him a nose full of boils. The curse’s unpredictable nature is further shown on the Hogwarts Express when Harry casts it at the same time George Weasley casts a Jelly-Legs Jinx on Vincent Crabbe. The combined effect causes tentacles to sprout all over Crabbe’s face. This curse is a good example of the more advanced, combative magic taught at Hogwarts – magic that goes beyond simply disarming or stunning opponents. Though not as dangerous as the Dark Arts, it’s designed to cause pain, distract, and disfigure, making it a surprisingly strong spell for a student to know.
3) Langlock

Langlock is a strong hex created by Severus Snape as a student, and detailed in his well-used copy of “Advanced Potion-Making.” It magically sticks a person’s tongue to the roof of their mouth, making it impossible for them to speak. Harry Potter learns this spell from the Half-Blood Prince’s book and successfully uses it during his sixth year. He first uses it on the mischievous poltergeist Peeves, who can only express his anger through gestures as he runs away. Later, Harry silences the grumpy caretaker Argus Filch with the spell to avoid being reported for breaking rules, which earns him cheers from other students. Although harmless, Langlock is a useful spell for stopping people from talking – preventing them from casting spells that require words or calling for assistance.
2) Disillusionment Charm

As a movie buff, I’ve always been fascinated by the subtle magic in the Harry Potter universe, and the Disillusionment Charm is a perfect example. It’s not quite an Invisibility Cloak – think of it as a super-powered camouflage. Instead of vanishing completely, it blends you into whatever’s behind you, like a human chameleon! The spell feels like a cold shock to the head, and then poof – you match your background. Remember when Mad-Eye Moody used it on Harry to sneak him away from Privet Drive? That was brilliant! It’s a really advanced piece of magic – they even use it on creatures like Hippogriffs to hide them from non-magical folks, and you can even weave it into regular cloaks to get a weaker version of an Invisibility Cloak. It’s a clever little spell, and it adds so much to the world-building.
1) Deprimo

The spell Deprimo is incredibly powerful, able to create large holes in solid objects with a single blast. It only appears once in the Harry Potter series. In Harry Potter and the Deathly Hallows, Hermione Granger uses it to blow a hole in the floor of Xenophilius Lovegood’s sitting room, allowing her, Harry, and Ron to escape from approaching Death Eaters. It’s one of the most destructive spells outside of the Unforgivable Curses, capable of both destroying structures and providing a quick getaway. While the movie adaptation shows Hermione (Emma Watson) creating a similar hole, she doesn’t say the spell’s incantation, as the filmmakers aimed for simpler spell effects.
