A Death Blow is the most common method of dealing a killing blow to upon an enemy, excluding ranked assassins. When dealing the killing blow to an enemy, an arrow is displayed on the screen. The enemy can be finished off by swinging the Wii Remote in the direction of the arrow, otherwise the Death Blow mode will end and the enemy will continue to attack.
Successful Death Blows cause slots at the bottom of the screen to start to spin. Matching three of these slot icons activates one of five different trances, or Dark Side Modes, depending on which three slot icons have been matched. Each executed Death Blow has a unique animation which varies between each beam katana models and the direction of the arrow displayed onscreen.
