Underwater Breathing is an ability that permits its users to inhale submerged. This might be refined through the use of gills, scuba hardware, making air pockets within water, or in any case discovering techniques to inhale submerged. Rarely, users might have the option to inhale within different fluids too, like magma or blood.

This varies from Self-Sustenance in that characters actually need to inhale, however can receive the oxygen they need to inhale from water.
