This is a port of Copper Lungs under the MIT license designed to support Create 0.5.1
Create: https://modrinth.com/mod/create
Miner's Lung: https://www.curseforge.com/minecraft/mc-mods/miners-lung
This mod activates the Diving Helmet/Copper Backtank when in "red/yellow" air quality zones to use the air supply instead of drowning. This gives you Water Breathing ("Free Breathing") and uses time/air from the tank as usual. Air is used at the same rate in either zone.
