Flagship Upgrade Requirements

Sea of Conquest Guide

Last Updated:

The main upgrading progress in Sea of Conquest is done through leveling up your Flagship. This is your main vessel and source of your combat and trading powers on the high seas as well as being home for your crew of sailors and a source of many resources.

You will also have your own fleet of small ships that add power and versatility to your abilities but they will be capped in level and number by your Flagships level.

Upgrading the flagship will require Gold to pay for it, but you will also need to fulfill other upgrade requirements in your ships cabins to unlock the levels. To help you plan for your upgrades and see what needs to be completed we have a list of the requirements for the early stages of the game.
