Duel between Arthur and Valiant

The duel between Arthur and Valiant occured when Arthur Pendragon and Valiant, both participants of the Tournament of Camelot, where fighting the last battle in the finale. Valiant had a magical shield, which he had previously used on Ewain and was planning on using against Arthur as well. Since he was not able to prove to the court that Valiant's shield mas magical, Merlin learned the animation spell so that he could bring the snakes to life during the battle.

Although Arthur had previously had a chance to forfeit he denied. He met Valiant in the Tournament pitch the next morning. Their duel was fierce. During the battle, Arthur knocked off Valiant's helmet, and to make it a fair fight, removed his helmed as well, much to the delight of the crowd who was watching. Then Valiant knocked him to the ground and stepped on his shield and disarmed him. Then he pinned him against the wall. Then Merlin arrived and cast the spell on Valiant's shield, turning the snakes to life. For a moment, Valiant didn't understand what is happening because he hadn't summoned the snakes. But soon after that he ordered the snakes to kill Arthur.

But before the snakes could harm the prince, Morgana threw a sword to Arthur, who catched it, killed the snakes and run the sword through Valiant, thus winning the tournament once more.
