Final Fantasy 14's new Island Sanctuary content provides players with a space to take care of animals, grow crops, and craft and export goods. As players build workshops and granaries, they can also upgrade them with more resources. However, to build more, the island requires expansion.

Expanding the island in Final Fantasy 14 takes patience, as the player will need to rank up their sanctuary level in order to unlock further expansion. Additionally, they will also sometimes need to craft mammet-sized builder tools. The island can expand five times, giving players plenty of plots to build upon.

Every Pathfinder Mk And What They Require

The specific mammets that work in expanding the island plots are called Pathfinder Mks. Speak to them to expand the island area, but expect to pay them in seafarer cowries with the price increasing each time. They will also require the player to be a specific rank and sometimes need particular tools.

Remember that seafarer cowries are best collected through visions done in quests and by keeping the workshop agenda full. Another way to get some is through weekly challenge logs.
