4.2 Submarines

Submarines!!! Lets talk Submarines. Super excited about them and would love others to share the excitement with and share speculations. Plus a good place to share when we start to learn what is needed.


Main things I have been wondering about:

1. Are certain mats more likely to be used for them over others, what would be best to stock? Right now our FC is just stocking a stack of each base crafting materials, with some raw mats to the side.
   
2. Would they be using the same materials used by airships to unlock their upper plans like the Shirogane castle do or will there more likely be new ones so everyone starts on the same footing?
   
3. What overall is to be expected from the submarines besides underwater instead of in the air?

If it's like last time, the base parts will use materials that can be gathered in the open world and then the higher level parts will require some materials only available from the voyages. What to expect? Judging from what I've seen, a new cutscene from launching them while the rest is a near carbon copy of airships.
