In The Witcher computer game[]

Stun is a critical effect with the following characteristics:

Geralt is incapacitated, i.e. control of Geralt is temporarily ineffective.
Opponents can kill Geralt with one hit (coups de grâce using ordinary swords or simple finishing blows using non-witcher style weapons).
When stunned, enemies' attacks are temporarily stopped as they remain afflicted.

Enemies who have less than 33% of their vitality left may be stunned and/or knocked down by any short weapon attack. Nevertheless, as with heavy weapons, they can not be used in stun-finishers, meaning that while Geralt performs a finishing move, only increased damage is dealt but the opponent will not die as a result unless the damage exceeds current vitality.
