Depth : Hidden World
by furti-two
Depth : Hidden World is a Forge world generation mod that adds an underwater dimension of ocean biomes, amber and platinum ores, and a pressure mechanic.
What it does
The mod builds a hidden underwater world of deep oceans, sunken structures and volcanoes, reached through a portal in the center of a sea structure. Deeper parts of the ocean hold new creatures, including an aquatic creeper variant, and ancient guardian ruins are buried in the seafloor. Amber and platinum ores generate in ocean-type biomes.
Below 20 blocks under the water surface, a pressure mechanic starts to damage the player. Surviving the depths requires armor that resists pressure, such as netherite, or a dive suit, which is heavy and slows vertical movement. Amber and platinum tools carry their own effects against enemies and blocks. The mod runs on client and server, so the server and every player need it, and it is published for Forge 1.16.5 under the MIT License, not as open source.
Key features
Underwater dimension
A dimension made almost entirely of water, with volcanoes and amber crystal formations to explore.

Players below 20 blocks under the surface take damage until they wear pressure-resistant armor or a dive suit.
Amber and platinum gear

Fisherman huts, underground temples and buried guardian structures are scattered through the ocean biomes.
