- As an action you can cast levitate on yourself without expending a spell slot. While concentrating on it, you also create a 5-meter-radius sphere of pure, fresh air that forms around you and moves with you. The spell keeps out hazardous gases and water, but solid objects can pass into the sphere. The air remains pure and clean for the duration of the spell.
Once you have used this action, you can't use it again until you finish a long rest.
