Breath control

Using Breath Control, a Jedi can literally numb the body's instinct to shut itself down after long periods without oxygen, allowing the user to be able to go without breathing for hours, even days. This is very effective in situations where the air is very thin; underwater; or in any environment with toxic fumes. The Jedi Exile used this power to negate the poisonous gases in a bar on Nar Shaddaa.
