Echolocation

You let out a piercing cry that sends invisible waves out in front of you, making everything in sight appear to ripple. 

Any solid object or surface in a 120ft long and 5ft wide line that is hit by your call bounces harmless sound waves back at you. For 1 minute, you know the location of the objects and surface that your Echolocation hit. 

This spell is harmless to people and creatures of every type. 

You cannot cast this spell through solid objects.
