We attempted to rank All the Harry Potter Spells. The list below is from the least useful to the most useful spells in the magical world. Also, In the end, I will show you the fantastic beast movie with all spells too.

All the Harry Potter Spells
Once upon a time, Harry Potter received his owl as well as his admission letter to Hogwarts School of Witchcraft and Wizardry. Since that day, millions of fans of his books have wished to receive their own admission letter from Hogwarts.
The magical school where young wizards learn All the Harry Potter spells and embark on other adventures. We muggles may never meet Harry Potter, study spells from Professor Flitwick (such as the death or light spell), or discover which house we are truly sorted into, but we may as well prepare by learning as many renowned Harry Potter spells as we can.
If your owl has been missing for several decades, or if your child is a Muggleborn witch or wizard waiting for their magical talents to be revealed.
All the Harry Potter Spells will ensure you (or your child) are at the top of your class when that letter finally arrives. After all, even if we can’t study all of Harry Potter‘s spells and what they do at school, there’s nothing wrong with little at-home charm practice.
From levitating spells to death, love, healing, and light spells, to those that make objects fly or may help you fight Voldemort without committing a crime, here are all the Harry Potter spells that every respectable witch and wizard should know.
Reparo
It’s a basic and simple spell, yet it’s quite useful. As her debut spell in the film series, Hermoine uses a version, “Oculus Reparo,” to repair Harry’s spectacles.
Riddikulus
This boggart-banishing charm turns something frightening into something amusing. Like when Neville Longbottom imagined the terrifying Professor Snape…then dressed him in his grandmother’s clothing.
All the Harry Potter Spells: Accio

This summoning charm may be used to bring an object closer to you, making it a perfect spell for the lazy.
Alohomora
Have you misplaced your keys? You’re sneaking into a location where you don’t belong? Taking care of mischief? You’ll never need a locksmith again thanks to this unlocking charm.
All the Harry Potter Spells: Crucio

This terrible spell, one of the three unforgivable curses, produces excruciating anguish for your target.
Powerful? Yes. Are you morally sound? Certainly not. Still, this one enters the list because of its unforgettable use by Barty Crouch Jr. as Alastor “Mad-Eye” Moody.
All the Harry Potter Spells: Petrificus Totalus
This is a full-body-bind curse, which is a very simple spell for a novice wizard or witch.
This tiny spell can quickly immobilize your opponent, as Hermoine did to Neville Longbottom.
All the Harry Potter Spells: Wingardium Leviosa
This levitation charm, one of the first spells taught to underclassmen at Hogwarts, may cause things like as feathers to soar or float.
All the Harry Potter Spells: Sectumsempra

Professor Severus Snape devised this curse when he was a young man. This evil magic inflicts wounds on your victim that may or may not heal.
The curse, while terrifying, created a big dramatic moment when Harry unleashed it on Draco.
All the Harry Potter Spells: Lumos
Why carry a torch when you can illuminate the tip of your wand with this charm? This is an incredibly helpful spell.
Android users may now switch on and off their handset’s flashlight by saying “OK Google, Lumos” and “OK Google, Nox.”
All the Harry Potter Spells: Expelliarmus

Put your opponent on the defensive with this disarming spell that knocks objects out of grasp, such as your opponent’s wand.
All the Harry Potter Spells: Avada Kedavra
The killing curse is another terrible spell…a Dark Arts weapon. It’s plainly the weakest spell of them all, yet its potency cannot be overlooked on such a list.
Having said that, we can’t rank this spell at the top of the list because Harry was able to defeat it with his own mojo.
All the Harry Potter Spells: Obliviate

This incantation has the power to wipe memories from your subject’s memory. If you happen to be Gilderoy Lockhart, you could unintentionally perform this spell on yourself.
