Unlocking the Black Pearl Ship
The Black Pearl is a second ship that you can unlock in The Caribbean upon raising the Leviathan’s level to 9 (max). To upgrade the Leviathan, you must collect white crabs found all throughout The Caribbean.
Once the condition is met, the Black Pearl can be found docked next to the Leviathan at Port Royal. You can then board the ship to ride it.
Unlocking the Black Pearl also rewards you with the Dreadnought trophy.
The Black Pearl has superior attack power and mobility to the Leviathan but is fitted with fewer guns. The Black Pearl also has lower HP than the Leviathan.
Below is a comparison of the two ships when both are fully-upgraded.
