Cybernetic

Metallic valves are surgically grafted onto the ends of certain tubes in your lungs that offer some protection against inhaled toxins, but also contain microscopic pressurizes that can supercharge the air you breathe. As a reaction, when you’re subjected to an inhaled affliction or other effect that requires you to be able to breathe, you can shut these valves to gain a +2 circumstance bonus to the saving throw.
