The possibilities of Sailing are really endless.
A big benefit of creating a new skill is that it constantly grows and gets improved upon post-release, so an underwater expansion is definitely within the realm of possibility and fits thematically with Sailing. If it’s something players really want, of course.
At the moment all of the Sailing mechanics are going to be on the Ocean (not underwater), as it’s not “diving”, so I don’t think underwater mechanics would form part of the core navigational design of the skill, — but it’s very open ended, so it all depends on your feedback and what players tell us about how they want the skill shaped up to be. ☺️
I’m so happy to hear you’re excited about refinement, I am eagerly anticipating what people will say when they read the blog and see the prototype! ❤️
