how to solo the boss battle?

[Juliana Maria]

I may be mistaken, but isn't there an option to solo the boss battle?

As for getting through the battle itself solo, I'd like to call it a near if not impossible task. If one has managed to accomplish such a feat, I congratulate them! My guess is you'll want to have your sailing set for the task specifically. Maybe max Take Cover and Open Fire. I suggest being mastered on your cannons and having fury and such maxed. Other than that I guess its just your own personal skill. Good luck to you in your task though!

And if you be asking how to bring a crew along on a boss battle simply go to the look out (L key) and choose accordingly. The crew will be given the option to join and then bring them along automatically i they select 'yes'. Hope I was able to answer some of your questions!
