The curst position of Defense Against the Dark Arts notwithstanding , Hogwarts does quite well in this section ( so what if   the teacher is reuse every single shoal year ? ) The bookman are taught some of the most telling spells bonk in the series , far more so than in other subjects like metamorphosis or Charms , for deterrent example .

In fact , whenHarry Potterstarts his own surreptitious club in the 5th year — Dumbledore ’s Army — the magic trick he trains them with is entirely based on his experience defending against the Dark Arts , so to verbalize . The leaning provided measures some of the more telling spells in the category against those that do n’t really make a sufficient encroachment .

Best: Salvio Hexia

Hermionecarries the group on her shoulders , a fact that is made painfully clear   on the final leg of their journeying .   After escaping from the Death Eaters at Xenophilius Lovegood ’s dwelling , the trio disapparate into the safety of a forest .

To safeguard themselves against any waylay enemies , Hermione puke an improbably powerful charm that allegedly forbid any hexes from aerate in their neck of the woods — in Latin , Salvio refers to " shelter " . This patch requires insistent uses depending on the area being covered .

Useless: Confundo

Confundo , also cognise as the Confundus charm , shin the thought processes of those it is used against , providing the castor with enough time to escape or come up with a plan of action .

This tour is not needs safe , however , as it can easy backlash much like Obliviate if not employed with precaution . More importantly , one must see the ethical consequences of this appeal :   omit thefiner degree of ascendence provided by the Imperius Curse , how different is Confundo , really ?

Best: Protego

An extremelyuseful magical spell , the Shield Charm can be employedin a salmagundi of position ( and come in a wide kitchen range of applications . ) The standard version is helpful in terms of blocking a large number of flak spells , or even existent objects ,   on occasion reflecting the projectile away from the body .

The advanced I , like Protego Maxima , Protego Horribilis , and Protego Totalum make declamatory - scale shields , but a dark mode also exists in the form of Protego Diabolica , an enchantment used by Grindelwald to furcate   his devotees from the betrayers .

Useless: Finite Incantatem

The magic that Finite is based on is quite interesting : and it has been a commodious method to negate the action   of small level hexes . In any suit , the General Counter - Spell , as it is also make love , is terribly ineffective against complex magic , for instance , literally any curse   Voldemort might have place on his Horcruxes .

Also , Finite Incantatem can not interpolate the resolution of any enchantment , which is why Snape is forced to use a complex mantra to help seal Draco ’s injury after Harry recklessly flings Sectumsempra at him .

Best: Impedimenta

This might technically be a curse , indicating a minus aura , but can be a lifeguard if one find oneself in struggle against a highly agile adversary .

The Impediment Jinx slows the opponent down , much like a deadening - motion reel , although its duration does not exceed more than a couple of seconds . Still , give how wizarding duel often occur at lightspeed ( assuming that ’s the speed of a spell ) ,   the reward proffered by Impedimenta can altogether change over   the tides of victory .

Useless: Reducto

If   stray incorrectly , Reducto can turn   rather virulent — imagine a patch , which can make thing to burst into dust , circumstantially come to an friend ( or even having it reflected towards the drug user . )

This obviously does n’t intend that it should n’t be used at all , considering that Dumbledore ’s Army default towards the Reductor Curse while purge the Ministry ’s Department of Mysteries for any cue towards Sirius ' whereabouts . To be honest , though , the fact that nobody got hit by it , hero or villain , was nothing more than unpatterned sure-enough portion .

Best: Expecto Patronum

A   Patronus is notoriously   challenging   to externalize ,   but this has more to do withthe castor ’s mental United States Department of State than their magic power . As long as one is strictly happy , or make do to reap forth any memories of comfort , they will be capable to   move Dementors   in the opposite commission as if   they were made of newspaper .

The Patronus creature is also   one of the safest elbow room to deport messages to other people ( although it is obscure if there is Dark Magic powerful enough to put down them . )

Useless: Riddikulus

By definition , the Boggart - BanishingCharm is mean to elicit the most absurd reply , as the Boggart is compelled to   transform itself from the caster ’s bad phobia to their most uproarious vision . Granted that it is quite amusing to watch Neville   attire Professor Snape in his grandma ’s mothbitten outfit , but how often do people come across these entity , really ?

Riddikulus works on a unlike spirit level , that of helping a young witch or wizard master their inmost fears , but it would be of no assistance in a genuine duel .

Best: Expelliarmus

The awesome thing about Expelliarmus is that it elegantly effloresce the moral inwardness of Harry Potter : the act of disarming someone might take away their artillery , but does n’t injure them in any way of life .

Several other magic spell can be used for the same purpose : Stupefy , Petrificus Totalus , or any one of the Unforgivables , but   this one is a sincerely passive way of terminate the battle . This is what Dumbledore   continuously tries to explain to   Harry , and this is why the latter ’s final spell against Lord Voldemort is Expelliarmus .

Useless: Rictusempra

Rictusempra was edited out of the cinematic adjustment , one of the several record spellsthat were unfairly axed ( primarily because watching Draco writhe around under an unseeable tickle - power would have been incredibly hearty . ) As part of DADA , the chance of this magic spell have any sort of determination is dreadfully low .

First of all , one would assume that Rictusempra only technically works on people prone to ticklishness , and secondly , it ’s not unimaginable to hold still for a few seconds and respond with a conclusive Avada Kedavra   in the middle of laughing one ’s guts out .
