Description
A simple mod I made that adds a new Dimension - the Deep Ocean!
It's literally the vanilla deep sea biome but it goes on forever and the water goes up to block 200. I needed an ocean dimension for a modpack I'm working on but couldn't find one so I just made this myself. Might come back to add some more content to the dimension eventually, but for now it's exactly what it says on the tin - a deep, endless ocean.
HOW TO USE
1) Build a portal out of prismarine blocks. Just like a nether portal.
2) Craft a Sea Key using a piece of kelp and a prismarine shard as shown in the image.

3) Use the Sea Key to light the portal and travel to the Deep Sea.
I will probably port to fabric when I have time because I also want to make a Fabric version of the modpack I made it for, but for now this is Forge only.
Feel free to use in modpacks and such, I bet it would go really well with any mods that add content to the ocean.
