Factions that export will receive VP and resources depending on the building they deliver to. Factions importing and receiving an opponent's ship will gain power. Ships will dig and build in adjacent hexes, so watch out! Ships can also be consumed and form new Dwellings. The ship movement and Dwelling actions add a new tactical movement element to the already deep strategy of Terra Mystica while maintaining perfect information.

The factions must also adjust to an entire new set of 12 round scoring tiles, four new Ship related Favors, three new bonus tiles, three additional power actions, town tiles, and two maps: Loon Lakes and Fjords. The maps and most of the round scoring may also used be used with the base game if desired.
