"He groped behind him and she forced the bundle of slippery cloth into his free hand. With difficulty he dragged it over himself, murmured, 'Nox,' extinguishing his wand light, and continued on his hands and knees, as silently as possible..."
—Harry extinguishing his wand whilst crawling through the tunnel into the Whomping Willow.[src]

The Wand-Extinguishing Charm (Nox) is a charm[1] that causes the light at the end of the caster's wand to be extinguished, thus acting as the counter-charm to the Wand-Lighting Charm (Lumos).


The Wand-Extinguishing Charm was invented by the same witch who invented the Wand-Lighting Charm, Levina Monkstanley. She invented the Wand-Lighting charm in the 18th century and invented the Wand-Extinguishing Charm around that time too, otherwise her wand would remain lighted indefinitely.[2]

This spell was taught to first year students in Charms class at Hogwarts School of Witchcraft and Wizardry in the 1984–1985 school year by Professor Filius Flitwick.[3] It is also detailed in The Dark Forces: A Guide to Self-Protection[1], and Book of Spells.[2]

Behind the scenes

  • In most of the video games, the Wand-Lighting Charm is extinguished by itself after some time, not requiring this spell.
  • On any Android phone (on Lollipop or better), if a user types Nox in the search bar on the Google app, the torch will turn off. Respectively, the Wand-Lighting Charm turns it on.
