Whisper Sense

You attune your senses to the air in a sphere whose radius is 30 ft. The sphere is centered on you and moves with you. For the duration, you have advantage on all Perception checks that involve hearing, and every creature that moves at least 5 ft. within the sphere must make a Dexterity saving throw against your spell save DC. On failure, you are aware of the path that the creature takes within the sphere. Creatures that are incorporeal such as ghosts or gaseous are immune to this effect, and creatures cannot be sensed while they are burrowing or underwater.

At higher levels. When you cast this spell using a spell slot of 2nd level or higher, you can extend the radius of the effect by 5 ft. per spell level above 1st.
