These ships can be fought at any time but it is best left until you have completed the majority of the game and have fully upgraded the Jackdaw! They are denoted by a red ship icon. There is one of these icons in each of the four corners of the map: northeast, northwest, southeast and southwest. These icons represent optional ‘boss encounters’ with legendary ships with very high ship levels, massive armour and top notch weapons.
These four naval battles are the hardest challenge you will face during your time with the Jackdaw and as such, you should level up all of its upgrades as much as possible before attempting to take down one of these monstrosities.
Defeat all 4 legendary ships.
In the following pages you’ll find short tactics guides to locating and taking down each of the four legendary ships. Note that these guides/tactics are by no means the only way to destroy these powerful enemies, but through trial and error (a heck of a lot of error) these are the best ways that I found to deal with them.
