Bottomless Ocean mod

To get to the dimension, one must build a portal out of prismarine and light it with a true heart of the sea (Currently obtainable only through cheats, but will be added soon to survival). Currently, your portal will appear at the bottom in a cave, where in survival you will die to the extreme pressure. In later veersions this will be changed to make the player spawn at the surface (Y 319). Here is all the content of the mod:

Tuna: The tuna is a fish found near the surface, drops raw tuna which can be cooked and gives slightly more saturation and hunger points than other fish.

Sailfish: this predator lurks slightly deeper than the rest of the fish, it is defensive and attacks the player if it is attacked. it hunts tuna, salmon and cod as well as manta rays. The Ai of this fish currently doesnt work the way you could expect.

Manta ray: These peaceful giants are found about as deep as sailfish. By feeding a manta ray tuna, one can tame it and ride it around the ocean. Keep in mind that it doesnt provide you with water breathing so you will need to use water breathing or get to the surface every once in a while. To go up and down use Ctrl (down) and Space (Up). Be careful of sailfish while riding a manta ray as they are aggressive to them.

Tripod fish: these fish are found at the deep seafloor alongside glow squids. Getting to them might not be easy, as the pressure is very strong down there which will almost instantly kill the player. They drop tripod fish legs which can be used to brew the pressure resistance potions.

Pressure: This is an effect that you get as you get deeper into the ocean. If you get deeper than Y 250, you get pressure 1 which just slows you down. below Y 200 you will get even slower and take a bit of damage. Y 150 and less will deal a ton of damage killing you quite fast. to resist pressure you can use the turtle helmet to resist 1 level, or the pressure resistance potion to nullify it completely.

Seastone: this is stone found below the surface, its a light blue stone which pairs great in building with prismarine, it is also the only stone that can be waterlogged.
