This boss wants to be a medieval monarch, maybe he was one in the land of Super Mario World.
He definitely knows how to joust.
And Luigi showed up to the wrong Renaissance Festival.
It’s took me a while to figure out how to beat him.
I tried using Gooigi as bait, and it did not work.
You have to wait for him to miss his jousting thrust, and then get to counter attack. If you somehow get hit, it’s quite a painful sting.
But I defeated him without dying once.
And with that, you get the elevator button to floor seven.
