The Gladiator

As fast as you can, you whip your sword around in a smooth arc and flawlessly parry the attack. Velkadin stumbles back in surprise at your speed, and you hammer him with combo blows. He manages to block them all, but barely. You feel your confidence soar. Twirling around, you swing your sword and give him a long, shallow cut on his jaw. Velkadin grips his wound and then stares in shock at the blood on his hands.
"I win." you say, sheathing your sword.
The crowd is cheering wildly at your first victory, but Velkadin is obviously angry.
"You've only scratched me!" he roared in fury. "I challenge you to complete this battle!"
You pause, knowing that Velkadin is challenging you to a fight until surrender. You also know that Velkadin will never surrender. But do you really want the crowd (not to mention that girl) to think you're a coward? You think over your choices....
