Deathblow is a Rogue ability from the Double Daggers Tree in Dragon Age: Inquisition.

Deathblow is an active ability with which you lash out with a vicious strike, and then again against a wounded enemy.

Unlocks: Thrill of Victory and Surprise Attack.
Deathblow can be modified using Thrill of Victory, which adds bonus damage and negates the cooldown if you kill your target, and Surprise Attack, which switches your second slash to a new target rather than moving in for the kill.
