Echolocate

You heighten your senses, granting yourself the ability to use echolocation. Until the spell ends, you have blindsight out to a range of 10 feet. If you become deafened while the spell is active, your blindsight is suppressed while you are deafened.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the range of the blindsight increases by 10 feet for each slot level above 1st.
