This mod adds a (mostly functional) oxygen sealing mechanic, that SOMEHOW! is compatible with Valkyrien Skies. Additionally, it adds the ability to create functional submarines (mostly functional submarines, to be precise) Fill tanks with Liquid Oxygen, use JEI for recipes, pump liquid oxygen into the vent block to PRESSURIZE AN AREA! THE FUTURE IS NOW!
To make a dimension unbreathable add it to the cconfig file Feel free to use in your modpacks! If you are looking for a config for Starlance use this:
