Aqualung
by peterwolfpl
Aqualung is a Fabric and NeoForge equipment mod that adds an underwater breathing item worn in the head armor slot, giving players more time below the surface.
What it does
The item extends the time a player can stay underwater by a large margin. Its oxygen bonus of +49 means air is consumed roughly fifty times more slowly than in vanilla. The change makes exploring, cave diving and building underwater far less tedious while keeping air a constraint that still matters. Survival worlds keep their sense of danger, and players still need to plan around their air supply.
Typical uses include ocean exploration, underwater bases, shipwreck and ruin visits, coral reef builds, flooded caves and long underwater mining sessions. The mod also includes a torch in a glass casing for lighting underwater builds. The server and every player need the mod installed. It is published for Fabric and NeoForge across four game versions, 1.21.11 – 26.3, and is released under the Apache License 2.0, which means it is not open source.
Key features
Breathing item for the head slot
A simple underwater breathing item goes into the head armor slot and works alongside the rest of the equipment.
Oxygen bonus
An oxygen bonus of +49 slows air consumption to about one fiftieth of the normal rate while submerged.
Glass Cased Torch
A torch encased in glass is added for placing light in underwater builds without losing it to the water.
Recipe from diving materials
The item is crafted from glass, a nautilus shell and turtle scute, which ties it to ocean resources.
