I have explored every piece of the map possible with a level 1 ship and have earned 200 EP. I cannot earn anymore. Upgrading to a level 2 ship requires a Lighthouse, and that requires 250 EP. So how do I earn the missing 50 EP??
Ashraman you should keep your ship constantly exploring those already-explored areas. In addition to the EP, you'll discover gold/grog/gems every few voyages.
