I understand that touching water causes sanity loss is a direct reference to Don't Starve, but I feel like this does not translate very well into Minecraft. This practically makes obtaining valuable resources and items like tridents, sponges, conch shells, and Heart of the Sea impossible. As trying to explore an Ocean Monument, looking for buried treasure that spawned in the water, or fighting off a horde of Drowned in hopes of a trident will cause the monsters from this mod to spawn very quickly. Those instances of them appearing makes them feel more annoying than scary.

including aqua infinity and respiration as a possible mitigating or outright immune impact would also be a good addendum.

Also, a good idea. I just believe that the shell is the best option because it makes sense from a logical standpoint. The player will think of the baby turtles they raised and protected from monsters while they wear the helmet, which will keep their mind away from the fear and stress of being wet or underwater. Maybe the water-based enchantments and potions could reduce sanity loss, but the turtle shell completely negates it.
