Solo Boss Battle?

[Jellyroll]

I stopped playing POTCO a while ago, and the boss battle had been down when I stopped playing. But now that I'm on summer vacation I've decided to start playing again.

Here are my stats:

Not: 31
Cutlass: 15
Dagger: 15
Pistol: 15
Doll: 15
Staff: 12
Grenade: 10
Sailing: Mastered (W/ Rank 1 Take Cover)
Cannon: 21


I was wondering what do you have to do for the boss? I've only tried it once, and it was just to see what I had to do, so I let them kill me.

Would it be possible to beat the boss battle with those stats? Also, what specifically do you have to do?

Thanks
