126 free Harry Potter Spells trivia questions with answers — entertainment quiz, new questions added Oct 2026.
This Harry Potter spell trivia quiz is entirely about the magic itself: the incantations, what they do, what counters them and who invented them. It starts with the ones every reader knows (Wingardium Leviosa, Lumos, Alohomora, Accio, Stupefy, Expecto Patronum) and works through the duelling spells, the healing charms, the household charms, the jinxes and hexes of the Marauders and the Half-Blood Prince, the protective enchantments Hermione cast around the tent, and the three Unforgivable Curses. Easy questions ask which spell disarms an opponent or which one lights a wand; the hard ones want the counter-charm to Prior Incantato, the spell that turns a staircase into a slide, the witch who invented the Mending Charm and the year Elizabeth Smudgling made the Disarming Charm famous. Every question gives four incantations or effects, so you have to know the spell, not just recognise the Latin. Every answer was checked against the Harry Potter Wiki's individual spell articles, which cite the books and Wizarding World, and each question carries the sentence that supports it.

Q 01Which disarming spell became Harry's signature and rebounded Voldemort's final Killing Curse?
Expelliarmus
Expelliarmus was such a habit that it gave Harry away among his six decoys: when he merely disarmed Stan Shunpike in the chase from Privet Drive, the Death Eaters knew they had the real one.
Q 02Which charm did Ron use to knock out a mountain troll with its own club?
Wingardium Leviosa
Wingardium Leviosa was the first spell Ron could think of; earlier that day Hermione had corrected the way he said it, and after it saved her from the troll the three became friends.
Q 03Which charm makes the tip of the caster's wand glow?
Lumos
Lumos, the Wand-Lighting Charm, makes the wand-tip shine; Harry casts it to follow the spiders into the Forbidden Forest in Chamber of Secrets and to see inside the tunnel under the Whomping Willow.
Q 04Which counter-charm puts out the light at the end of a wand?
Nox
Nox put out two wands at once in the Shrieking Shack: Harry and Hermione whispered it together so that whoever was upstairs would not see them coming.
Q 05Which charm summons a named object toward the caster, even one out of sight?
Accio
Accio, the Summoning Charm, finally worked for Harry at two in the morning, after a day's practice with Hermione; hours later he used it to call his Firebolt from the castle to the dragon's enclosure.
Q 06Which of the three Unforgivable Curses places its victim completely under the caster's control?
Imperio
Imperio, the Imperius Curse, let Barty Crouch Sr keep his own escaped son hidden at home for years; then Voldemort's side freed the son and turned the same curse on the father.
Q 07Which curse did Harry cast, almost uselessly, at Bellatrix Lestrange in the Ministry Atrium?
Crucio
Crucio: after Bellatrix killed Sirius, Harry chased her into the Atrium and cast the Cruciatus Curse, which only knocked her off her feet because, she taunted, he did not truly mean it.
Q 08What is the penalty for using an Unforgivable Curse on another human being?
A life sentence in Azkaban
A life sentence in Azkaban: so 'Moody' (Barty Crouch Jr in disguise) told the fourth-years in Goblet of Fire, though Crouch Sr had authorised Aurors to use the curses against Death Eaters in the first war.
Q 09What colour of light accompanies the Killing Curse?
Green
Green: a jet of blinding green light accompanies Avada Kedavra, which kills instantly and leaves no mark, so Muggle doctors found nothing wrong with the murdered Riddles.
Q 10Which incantation produces the silvery guardian that drives off Dementors?
Expecto Patronum
Expecto Patronum troubles many qualified wizards, yet Harry cast it at fifteen to save his cousin Dudley from two Dementors, and was tried for underage magic by the full Wizengamot and cleared.
Q 11What animal form does Harry Potter's Patronus take?
A stag
A stag, the shape his father James took as the Animagus Prongs: when it charged the Dementors by the lake, Harry thought his dead father had cast it, then found that he had done it himself.
Q 12Whose Patronus, a doe, led Harry to the Sword of Gryffindor in the Forest of Dean?
Severus Snape
Severus Snape's doe matched the Patronus of Lily Potter, whom he had loved since childhood; in the memories he left Harry he conjures it and, asked 'After all this time?', answers 'Always.'
Q 13Who gave Harry private anti-Dementor lessons to teach him the Patronus Charm?
Remus Lupin
Q 21Which charm did Hermione cast on Cormac McLaggen during Gryffindor's Keeper trials?
Confundo
Confundo, the Confundus Charm, befuddles its target; Hermione used it so Cormac McLaggen missed a save at Keeper trials, and 'Moody' said an exceptionally strong one had bamboozled the Goblet of Fire.
Q 22Which curse causes its target to explode?
Confringo
Confringo, the Blasting Curse, cost Harry his wand: when Hermione fired it at the snake Nagini in Bathilda Bagshot's house, the spell ricocheted round the room and apparently snapped it.
Q 23Which curse did five of Harry's friends bellow together to smash the prophecy shelves in the Department of Mysteries?
Reducto
Remus Lupin, that year's Defence Against the Dark Arts teacher, had no Dementor to practise on, so he brought a Boggart, which turned into one whenever Harry stood in front of it.
Q 14Who devised the method of using Patronuses to carry spoken messages?
Albus Dumbledore
Albus Dumbledore devised the messenger Patronus, a technique used only by the Order of the Phoenix; Kingsley Shacklebolt's lynx used it to warn Bill and Fleur's wedding that the Ministry had fallen.
Q 15Which spell defeats a Boggart by forcing it into a form the caster finds funny?
Riddikulus
Riddikulus, cast while picturing something funny, forces the Boggart into that shape with a whip-crack; Neville's took the form of his Potions master dressed in his grandmother's clothes and vulture-topped hat.
Q 16Which charm makes its target buckle with laughter, weakening them?
Rictusempra
Rictusempra, the Tickling Charm, hit Malfoy in the stomach as a jet of silver light at the Duelling Club; he sank to his knees, barely able to move for laughing.
Q 17Which spell made Harry's legs jerk uncontrollably when Malfoy cast it at the Duelling Club?
Tarantallegra
Tarantallegra, the Dancing Feet Spell, later cost Harry the prophecy: a Death Eater cast it on Neville, and as his legs flailed the glass sphere fell from his torn pocket and smashed.
Q 18Which charm, nicknamed the Thief's Friend, unlocks doors and windows?
Alohomora
Alohomora, the Unlocking Charm, got Hermione, Harry, Ron and Neville through a locked door as they fled Filch in their first year, and straight into the forbidden corridor guarded by the three-headed dog Fluffy.
Q 19Which spell locks a door so that it cannot be opened by hand?
Colloportus
Colloportus, the Locking Spell, seals a door with a squelching sound; Hermione used it in the Department of Mysteries to lock doors against the pursuing Death Eaters.
Q 20Which charm erases specific memories from a person's mind?
Obliviate
Obliviate, the Memory Charm, made Gilderoy Lockhart famous, since he wiped the wizards whose deeds he claimed; cast through Ron's broken wand it backfired and erased his own memory.
Reducto, the Reductor Curse, blasts solid objects apart: at one D.A. practice Parvati Patil cast it so well that she reduced the table in front of her to dust.
Q 24Which spell, nicknamed the Stunner, renders its target unconscious?
Stupefy
Stupefy, the Stunning Spell, fires a jet of red light that knocks the target out; several at once, from the Ministry wizards who came for Hagrid, put Professor McGonagall in St Mungo's.
Q 25Which curse did Hermione cast on Neville when he tried to stop the trio leaving Gryffindor Tower?
Petrificus Totalus
Petrificus Totalus, the Full Body-Bind, later caught Harry himself: Malfoy cast it on him as he hid under his Invisibility Cloak on the Hogwarts Express, then stamped on his face.
Q 26What is the incantation of the Leg-Locker Curse, which binds the victim's legs together?
Locomotor Mortis
Locomotor Mortis, the Leg-Locker Curse: Malfoy hit Neville with it in their first year, and Neville bunny-hopped all the way up to Gryffindor Tower, where Harry gave him a Chocolate Frog.
Q 27Which charm throws up an invisible barrier that sends jinxes back at the attacker?
Protego
Protego, the Shield Charm: Harry taught it to the D.A. in his fifth year, and Fred and George built it into Shield Hats, which the Ministry bought by the hundred for its staff.
Q 28Which Half-Blood Prince curse, marked "for enemies", did Harry use on Draco Malfoy in a bathroom?
Sectumsempra
Sectumsempra, the Half-Blood Prince's own invention, slashes the victim as if by an invisible sword; its inventor healed Malfoy with a song-like counter-curse and later took off George Weasley's ear with it by accident.
Q 29Which jinx, meant to be cast nonverbally, hoists its victim into the air by the ankle?
Levicorpus
Levicorpus, a nonverbal jinx from the Half-Blood Prince's book: James Potter used it to dangle its own inventor upside down by the lake in their fifth year, and Liberacorpus is the counter-jinx.
Q 30Which charm fills the ears of everyone nearby with a buzzing so that a conversation cannot be overheard?
Muffliato
Muffliato, from the Half-Blood Prince's book, fills nearby ears with an unidentifiable buzzing; Hermione disapproved of it at school and refused to talk while it was in use, then cast it herself when the trio were on the run.
