Magic doesn’t exist, but if it did, the most useful spells in Harry Potter wouldn’t be the flashy duel-enders. They’d be the ten below, the charms and curses a Muggle would use every day. Think summoning the remote instead of hunting for it, lighting a dark hallway without a flashlight, or mending a cracked phone screen in a second. Here’s what each one does in the books and films, and why it would be worth having.
Updated October 30, 2026.
Some spells in this series would be truly useful in real life, as opposed to the ones that only matter in a duel with a Dark wizard. The practical ones tend to be the quiet background spells. Think of the charm that unlocks a door, not the one that blows it off its hinges. Have you ever been so fed up with chores that you wished you could wave a wand and be done? Most of us have also watched a kid melt down in the middle of a store and wished for a magic fix. And almost everyone has said something awkward in front of a crowd and hoped it would all be forgotten. With Halloween coming, let’s step into that world of make-believe for a bit. If you want the real history behind witches, read our myths about witchcraft.
The Summoning Charm
Incantation: “Accio”
Application: The Summoning Charm pulls a named object straight to the caster’s hand. Harry famously uses it to call his broomstick during the first task of the Triwizard Tournament, then flies past a dragon to grab the golden egg.
For a Muggle, this one solves the most common household annoyance there is. Wizards use it for anything, from a quill to a jug of butterbeer. For us it would be keys under the couch, the remote wedged in the cushions, or the lawnmower when you need it. Need the Clorox wipes when the kids make a fresh mess? All of it arrives in the time it takes to say one word.
The Imperius Curse
Incantation: “Imperio”
Application: This one is genuinely dark magic. It puts the target under the caster’s control, and it is one of the three Unforgivable Curses, though it is the only one a strong enough will can resist. In Goblet of Fire, Barty Crouch Jr., disguised as Mad-Eye Moody, casts it on his fourth-year students in class. Harry is the only one who fights it off.
Some of these spells are morally dubious, and this is the worst of them. It is a bossy, overbearing curse, and in the books it is called “Unforgivable” for a reason. Still, picture a toddler mid-meltdown, or a kid who won’t do what you ask, and you can see why it made the list. Used responsibly, if that is even possible, its usefulness is hard to deny.
The Memory Charm
Incantation: “Obliviate”
Application: The Memory Charm can erase a specific memory or, used carelessly, a person’s entire sense of who they are. In Chamber of Secrets, Gilderoy Lockhart tries it on Harry and Ron using Ron’s damaged wand. The wand backfires and wipes Lockhart’s own memory instead.
Lockhart is the warning label. Still, I can’t help thinking a light touch of it would be handy after you misspeak while giving a talk or trip over your words in front of a crowd. One flick and nobody remembers. It should only ever be used with discretion.
The Unlocking Charm
Incantation: “Alohomora”
Application: This charm opens locks on command. In the “Midnight Duel” chapter of Sorcerer’s Stone, Hermione grabs Harry’s wand, taps a locked door on the forbidden third-floor corridor and says “Alohomora!” The trio uses it again and again after that.
No more locked-out-of-the-house calls to a locksmith, and no more digging through a junk drawer for the right key. Anyone who has ever misplaced their keys at the worst moment knows how good that would feel. Harry, Ron and Hermione are noisy troublemakers, and they use it to sneak around Hogwarts and beyond more times than we can count.
The Healing Charm
Incantation: “Episkey”
Application: Episkey heals minor injuries such as broken noses, broken toes and split lips, and it can ease a headache. Nymphadora Tonks uses it to fix Harry’s broken nose at the start of term in Harry Potter and the Half-Blood Prince.
A stubbed toe or a split lip fixed in the time it takes to say the word would cut out a lot of doctor visits for small stuff.
The Disillusionment Charm
Incantation: Not stated in canon
Application: This charm makes the caster blend into their surroundings like a chameleon rather than turning them fully invisible. Alastor “Mad-Eye” Moody uses it on Harry in Harry Potter and the Order of the Phoenix to hide him during the flight from Privet Drive to Grimmauld Place.
Almost everyone fancies being invisible at some point. Picture being the fly on the wall in the room where the big decisions get made. You could listen in on conversations nobody would say out loud. It’s fun to fantasize about, even if the real thing would be closer to camouflage.
The Shield Charm
Incantation: “Protego”
Application: The Shield Charm throws up an invisible barrier that blocks spells and physical force alike, though not the Unforgivable Curses. Harry learns it while preparing for the third task in Goblet of Fire, teaches it to Dumbledore’s Army in Order of the Phoenix, and uses it to protect his friends at the Battle of Hogwarts.
Most Muggles won’t need to block a curse. But the shield also stops physical things, so it would be a handy way to stop anyone who comes at you. A barrier that stops anything thrown your way is still an easy sell.
Water-Conjuring Charm
Incantation: “Aguamenti”
Application: Aguamenti, officially the Water-Making Spell, produces a jet of clean water from the wand tip. In Half-Blood Prince, Harry uses it to fill Dumbledore’s goblet in the cave, and later he and Hagrid use it to put out the fire at Hagrid’s hut.
For a Muggle, I’d skip the firefighting and use it to stay hydrated. Clean water on demand would matter a lot more than a duel spell on any ordinary camping trip or hike. You would never go thirsty again.
Wand-Lighting Charm
Incantation: “Lumos”
Application: Lumos lights the tip of the caster’s wand like a small lantern. Harry, Ron and Hermione use it constantly while exploring the darker corners of Hogwarts and, later, while on the run in Deathly Hallows.
It’s the one spell on this list with a near-exact Muggle equivalent already in every phone. Anyone who has fumbled around a dark room for a phone knows the appeal. A wand would make a flashlight pretty much pointless, and you would not have to find anything first.
The Mending Charm
Incantation: “Reparo”
Application: Reparo fixes broken objects on the spot. A variant, “Oculus Reparo,” repairs glasses: Hermione uses it on Harry’s in the Chamber of Secrets book, and on the Hogwarts Express in the first film. In Half-Blood Prince, Dumbledore and Slughorn use the base spell to put a wrecked living room back together.
This is probably the most useful spell on the list. Harry is always getting into scrapes that leave his glasses broken and crooked, and one quick spell sets them right. For us it is the cracked phone screen, a broken mug, or a car transmission on its way out. Reparo, and you skip the repair bill. A clogged toilet? Skip the plumber and cast it. Spilled water on your laptop? Reparo, and no new one to buy. Think of all the repair shops that would have nothing to do.
