But if your party is less inclined to play friendly (or perhaps, less willing to bow to the whims of pirates), then the Pirate Captain stat block is one of the better ones to have at hand.
A pirate captain is nothing without their trusty crew ... Crew members who feel awesome in particular get a big stat bonus which makes them more effective in naval combat as well as deck combat.
Combining DnD-style dungeon crawling ... each with their own unique abilities. The Captain completes random slots on the board as he collects gold. The Pirate Queen commands higher dice rolls ...
