Recommended mods:

Origins (Forge) https://www.curseforge.com/minecraft/mc-mods/origins-forge

Realm RPG: Sea Dwellers https://www.curseforge.com/minecraft/mc-mods/nocubes-sea-dwellers

The Origins mod adds a great Murfolk player race that allows for underwater breathing, better mining speeds, and vision at the cost of being unable to breath on land, and the Sea Dwellers mods adds awesome underwater villages that spawn in oceans, this mod should have some crafting compatibility with some of the new resources added in that mod if everything is working correctly.

For Spooky Thunderstorms get:

Dark Waters https://www.curseforge.com/minecraft/mc-mods/dark-waters

The Dark Waters mod makes thunderstorms in the ocean absolutely terrifying, which will make you think twice before you decide you want to get the resources needed for your next ritual.
