"There! They'll repel water!" — Hermione Granger after casting the charm on Harry Potter's glasses during a thunderstorm[src]

The Impervius Charm[4] (Impervius)[4][1] was a charm that made an object repel water[1] and mist.[3] This could be used to allow someone better sight in bad weather conditions by preventing the rain from hitting their faces.[4]

This charm did not repel solid objects, as seen when Hermione Granger attempted to defend herself and her comrades against the cascading and burning treasures in the Lestrange Vault.[5]

History[]

"Good day, students! Today we will be learning the Impervius Charm. If you're ever caught in a rainstorm and forgotten your umbrella... The Impervius Charm will repel rain and keep water out of your eyes! Before you learn by doing, learn by watching me demonstrate the Charm!" — Professor Flitwick to his seventh-years[src]

During the 1990–1991 school year at Hogwarts, Professor Flitwick taught seventh-year Charms students how to perform this spell.[6]

On 2 September 1997, this charm was recommended by Hermione Granger to Ron Weasley as a way of protecting Corban Yaxley's belongings from the rain in his Ministry office until it could be stopped.[7]

Etymology[]

The incantation is derived from the English word "impervious", which means "not allowing something to pass through" or "not penetrable".

Behind the scenes[]

• The charm may also be related to the Imperturbable Charm, an enchantment used to completely block everything out of a given area for a certain period of time, including sound and presumably water.
• In the Harry Potter films and video games, Harry and other Quidditch players use Quidditch Goggles to protect their eyes instead.
