Echo

You hold out your hand and magically enhance a sound, causing it to echo in a 10 foot square around where the sound originated for the duration. Any creature starting its turn in this area must make a dexterity saving takes 1d6 thunder damage and must make a Constitution saving throw, becoming deafened on a failed save for 1 minute. If the noise this spell targeted already caused thunder damage that damaged is increased by 1d6 and then this spell ends.  

At Higher Levels. If you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
