"He raised his own wand, pointed it at Winky, and said, “Rennervate!” Winky stirred feebly."
Amos Diggory uses the spell on Winky[src]

The Reviving Spell[4] (Rennervate)[1] is a charm that awakens whomever the caster's wand is pointed at.[3] Consequently, it serves as the counter-charm to the Stunning Spell.


This spell is accompanied by a flash of brilliantly coloured red light.[1]

This can be used to counteract a single Stunning Spell, although it is ineffective against multiple Stunners hitting an individual.[5] It's also ineffective against Dark Magic such as the Drink of Despair.[1]

The original incantation was Enervate, which means "to weaken".[7] Due to this misconception, J. K. Rowling officially renamed it to "Rennervate",[7] which means "to energize".

Behind the scenes

  • Despite this spell being used to revive unconscious people, it is ineffective against the Full Body-Bind Curse, which can be undone by the General Counter-Spell. This is probably because the former is a curse, and also because of the fact that rather than being rendered unconscious, the victim is being paralysed and still conscious. Rennervate acts as a more specific counter-charm to Stunning Spells, Sleeping potions and presumably the bewitched sleep spell as well, but can also be used on sleeping targets anyway.
