"There! They'll repel water!"
Hermione[src]

The Impervius Charm[4] (Impervius[4][1]) was a charm that caused an artefact to become waterproof[1] or allow someone better sight in bad weather conditions by preventing the rain from hitting their faces.[4] The charm could also be used to repel mist[3].
