Ending Blow

Ending Blow is the first Hidden Skill in Twilight Princess that is taught by the Hero's Spirit. Once a foe is knocked down, the A Button symbol, followed by "Finish", will appear at the bottom of the screen. If the A Button is pressed, Link will jump at the downed foe and plunge his sword into the enemy, killing it. However, if the enemy moves out of the way, Link will be vulnerable while trying to get his sword out of the ground.The ending blow will kill any enemy with a single hit.It is also the only hidden skill you must learn as you'll have to finish ganondorf in the final fight with the ending blow
