Unlocking and Utilizing the Free Company Submarine in FFXIV: A Comprehensive Guide

Dive into the underwater world of Final Fantasy XIV with your Free Company's very own submarine! This guide details the process of acquiring and utilizing this exciting feature, introduced in the Stormblood expansion.

Acquiring the FC Submarine:

Free Company Membership and Rank: Ensure your Free Company (FC) exists and has reached rank 6. This rank unlocks access to necessary vendors for Ceruleum Tanks. Reaching rank 6 is relatively straightforward; encourage FC members to participate in in-game activities like dungeon clearing, leveling, crafting, and gathering.
Crafting the Submersible: Navigate to your FC's workshop. Interact with the schematic board to obtain the submersible recipe. Gather the required materials, and the submersible will be added to your FC's crafting log, ready for construction.
Securing Dive Credits: Purchase Dive Credits from Resident Caretaker NPCs located in the following housing districts (requires FC rank 6):
- 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
Each Dive Credit costs 10,000 Company Credits.
Submersible Registration: Once you have Dive Credits, register your newly crafted submersible via the voyage control panel within the Company Workshop.
