How did you fight the knight?

I'm not asking for a guide, I'm genuinely curious to know what kind of strategy you used. Who did you give the shadow mantle to? (Unless you went in mantleless, which crazy but props to you) Did you only use rude busters or normal attacks too? Did you take your time to heal/defend or went full offense for as long as you could take it? Did you sacrifice any character along the way? Stuff like this. I'm genuinely curious
