You begin carefully regulating your breath so that you can continue playing longer or keep breathing longer in adverse conditions.

Until the spell ends, you can breathe underwater, and you can utilize bardic performances that would normally require breathable air. In addition, you have advantage on Defensive Rolls against gases and environments with adverse breathing conditions.

Inhales seamlessly intertwine with exhales, an unbroken circle of air. Your breath becomes a resilient melody, enabling you to play longer, endure, and conquer adverse environments with unwavering endurance.
