Atmospheric Pressure
by pporz
Atmospheric Pressure is a NeoForge equipment mod that adds air pressure mechanics, so altitude and depth start to matter during survival play.
What it does
High places and deep caves change the conditions a player has to handle. Climbing above Y 150 without proper protection causes altitude sickness, and thin air brings Mining Fatigue, which makes gathering resources in high mountains much slower. Players are expected to prepare before reaching the highest peaks or the deepest caves.
Two equipment pieces answer these conditions. The Oxygen Mask goes in the helmet slot and protects against high-altitude fatigue, while the Pressure Boots go in the boots slot and let a player move freely through deep-pressure zones. The mod is built for NeoForge and has files for 1.21.8 only. Servers that run it need every player to install it too. The code is released under the MIT License, but the project is not open source, and a public issue tracker is linked from the project page.
