These metallic nodules were created by Ego Ultd. to allow their marines to operate freely in the void and within Trimino waters during the first interstellar war. These lungs are placed by an artificer in a complicated surgery, replacing your normal lungs. The lungs allow you to breathe normally, even in an antimagic field, and their breathing function can't be suppressed by magic. Outside an antimagic field or any other effect that suppresses magic, these lungs allow you to breathe normally in any environment (including the void), and you have advantage on saving throws against harmful gases such as those created by a cloudkill spell, a stinking cloud spell, inhaled poisons, and gaseous breath weapons . As an action, you can use these lungs to exhale a gust of wind, as if you had cast the gust of wind spell (spell save DC 15) with no components. This property of the lungs can't be used again until after your next long rest.
