Nobility's more than money or a title, it's how you carry yourself. Luke's regal bearing took a long time and many a battle to obtain, but it's his. He went from adoring Van to bringing him down before he could destroy the world. It's no wonder that fighting a robot doesn't even make him blink. Luke's a good fighter, far too competent to belong in light. Cinnamon's tricks won't do more than slow him down, as the owner of the Jewel of Lorelai has the mental, physical, and emotional toughness to take down this healer robot with his usual throughness.
