How to Unlock the Free Company Submarine in FFXIV

To embark on this underwater journey, you must first join a Free Company in FFXIV. If you're part of a new FC, aim to elevate it to rank 6. This level unlocks access to essential vendors for purchasing Ceruleum Tanks, which can be achieved by engaging in various in-game activities such as clearing dungeons, leveling up, and participating in crafting and gathering.

Next, head to your FC's Company Workshop in your FC house. Interact with the schematic board to unlock the submersible recipe. Once you've gathered all the required materials, the submersible will appear in your FC crafting log, ready for construction.

But that's not the end of it. To enable subaquatic voyages, you'll need Dive Credits. These can be purchased from Resident Caretaker NPCs in various housing districts:

  • Empyreum: X:10, Y:12
  • Lavender Beds: X:12, Y:8
  • The Mist: X:11, Y:11
  • Shirogane: X:10, Y:14
  • The Goblet: X:11, Y:10

Remember, you need to be at FC rank 6 to buy Dive Credits, and each credit costs 10,000 Company Credits. Once you have your Dive Credits, register your submersible at the voyage control panel in the Company Workshop.

All Voyage Sectors and Submarine Ranks

Now that your submersible is ready, let's dive into the voyage sectors and the ranks required to explore them.
