Instant Oxygen Refill
by Mistysnowfox
Instant Oxygen Refill changes how breath recovers underwater, so air returns in one step rather than gradually.
What it does
Once the mod is installed, breathing air is restored at once after a player surfaces, matching how recovery worked in older versions of the game. Potions of water breathing and conduits also refill oxygen fully in a single action. The mod runs on the server alone, so players join without installing anything.
NeoForge is the only loader with files, and builds cover 1.21 – 1.21.11. The license is the MIT License, and the code is not open source in the catalog sense. The latest file is 1.0.0 for 1.21.11, published 2026-05-16.

Are you annoyed by how slowly the oxygen refills? This mod makes the oxygen refill instantly, like in pre-1.13 versions! It also makes water breathing potions and conduits refill oxygen fully.
