Causes explosion

"As they soared upwards, away from the two remaining Death Eaters, Harry spat blood out of his mouth, pointed his wand at the falling sidecar, and yelled, 'Confringo!' He knew a dreadful, gut-wrenching pang for Hedwig as it exploded..."
—Harry Potter's use in the Battle of the Seven Potters[src]

The Blasting Curse is a spell that causes anything that the spell comes into contact with to explode. The incantation is Confringo. Confringo is probably one of the most destructive curses in the spell arsenary, aside from Reducto. The difference between this spell and Expulso is that Confringo uses heat to cause explosions, and Expulso uses pressure.

Known uses

Possible uses


Hermione using this curse against Nagini.

  • This spell may have been the cause of the explosion which killed Fred Weasley during the Battle of Hogwarts.
  • On 1 November, 1981, Peter Pettigrew may have used an extremely powerful blasting curse to decimate a street and kill twelve Muggles at once while evading Sirius Black, who was blamed for the crimes and Pettigrew's alleged death. [2] The explosion was so fierce, it left a massive crater in the street, with the pipes showing. The Ministry gave an excuse of a "gas leak" to the surviving Muggles, and thought that Black was the one who used the curse.

Known practitioners


Confringo is Latin for "I break".

Behind the Scenes

  • In Harry Potter and the Deathly Hallows: Part 2 Professor McGonagall possibly uses the Blasting Curse to duel against Snape (just in case this is not the Blasting Curse, it is referred to as the Fiery offensive spell), defeating Amycus and Alecto Carrow in the process. The curse McGongall used, however, could have been a spell that shapes fire into magnificent, swirling shapes, and when hit it causes the victim to pass out from heat exhaustion.
  • In Harry Potter and the Deathly Hallows: Part 2, Harry uses the Blasting Curse against Nagini in an attempt to kill her and possibly to provoke Voldemort to chase Harry, so the snake would stay behind unprotected. Immediately after this instance, Voldemort also casted several Blasting Curses at Harry as he jumped into a corridor and escaped Voldemort's wrath.
  • Both this spell and Expulso share similar effects, though - unlike the latter - Confringo is sometimes accompanied by fiery explosions. The reason for this may be that Confringo is the result of a sharp, local temperature increase where as Expulso increases the local pressure to cause explosions. However, in the Deathly Hallows video games, Confringo is an explosive spell, while Expulso serves as some sort of "machine gun" spell.
  • In different varieties of games and films, the colour of Confringo varies. Its two main colours so far are a light blue and purple, or simply a fiery explosion.
  • A spellbook for this spell could be found nearby an old building close to an Acromantula lair and some abandoned nuclear power plants.
