🌍 Atmospheric Pressure
Atmospheric Pressure is a survival-enhancing mod that adds a new layer of realism and challenge to your Minecraft world. Your environment now reacts to your altitude, forcing you to prepare before venturing into the highest peaks or the deepest caves.
🛡️ Key Features
[Altitude Sickness] ⛰️
When climbing above Y = 150 without proper protection, the thin air will cause Mining Fatigue, making it much harder to gather resources on high mountains.
[Deep-Sea Pressure] 🕳️
Venturing into the depths below Y = 0 without the right gear will subject you to intense pressure, resulting in a Slowness effect that hinders your movement.
[Specialized Gear] 🛠️
To survive these harsh conditions, you must craft and wear specialized equipment:
Oxygen Mask: Protects you from high-altitude fatigue (Equip in Helmet slot).
Pressure Boots: Allows you to move freely in deep-pressure zones (Equip in Boots slot).
