How to unlock the House Champ (King Knight) achievement in Shovel Knight: Treasure Trove - Definitive Guide
If you play and beat cardia (the purple lady) at the top of the airship she tells you to come back once you've cleared all 4 houses.
Once you've done so go back and talk to her and you'll have to play and beat a transformed version of her.
After you beat her in Joustus you'll have to fight a different transformed version of her, which was kind of tough. I don't know if I went into the fight with zero vigor or if it sets it to zero but it took me a fair amount of tries to beat her since I had zero vigor. I was using the armor that restores vigor but couldn't find a useful heirloom for the fight anyways. I had a healing decree which I saved for when I was pretty close to beating her and thought I had a good chance. She has 4 different colored crystals each with their own attack, you have to bash them when they're low enough then bounce on top and then bash or bounce on top of the boss.
Hope this helped, good luck. Also not only are you rewarded with the achievement after you beat her but you get a useful item for a different achievement as well.
