The Abyss is a new dimension added by this mod, and it's accessed via portal; the frame blocks can be found like ore in any type of ocean biome (Vanilla ocean biomes), to light the portal you will need a Heart of the Sea Steel, which is shapelessly crafted with flint and steel and a heart of the sea.
This mod is a WIP and is currently very barebones, however I will be updating it as I get more content lined up.
Current state the mod adds:
Biomes: 3
- Abyss Depths
- Abyssal Expanse
- Cragfield (Early version)
Creatures: 3
- Abyssal Salmon
- Abyssal Anglerfish
- Deepsea Crab
Armor Sets:
- Diving Suit (Required to access the abyss.)
I would highly recommend an recipe checker mod such as JEI, as the recipes added by this mod can be rather complex.
