This spell (incantation unknown), which produces a powerful bluish-white bolt, can be used to break large magical protections such as Protego horribilis.[1]


It was used by Lord Voldemort in 1998 to break the defensive enchantments cast over Hogwarts Castle during the Battle of Hogwarts. It seemed to strain even him to cast it, though this may have been because he was illegitimately using the Elder Wand at the time.[1]

Voldemort breaking the shield causing the Elder Wand to crack

  • In the second film adaptation of Harry Potter and the Deathly Hallows when this spell was used by Voldemort with the Elder Wand, it cracked the Elder Wand slightly along its length. Whilst one may take this as an outward sign of the power required by this spell, it should be noted that Voldemort was not the master of the wand then, so it may be easier to cast in other circumstances.
  • There is no actual mention of this spell in the novel.
  • It is possible that this is the Lightning Spell (the spell that Voldemort uses upon retrieving the Elder Wand from Dumbledore's tomb in order to test its immense power), as it has a similar colour and texture to that spell.
  • It is debatable whether this spell's primary purpose is actually shield-penetration; it is possible that it is merely a spell that channels enormous amounts of raw brute power, which in this particular case was used to overwhelm Hogwarts's shields. This hypothesis is all the more likely if it is indeed the same as the Lightning Spell
  • In Harry Potter and the Half-Blood Prince, Dumbledore uses an unidentified spell to temporarily lift the Hogwarts enchantments while he and Harry pass through on broomsticks on their way back from the cave. If the spell discussed here is indeed specifically a shield-breaking one (see above speculation), it is possible he used it. 2a4ccd4d-8857-7814-09cf-de5c1633887d
