Echo Location

You create a burst wave of silent clicks only the intensely trained can hear and travels up to 100 feet away. The burst will echo back to you revealing the location of objects. The direction and a very short glimpse of the silhouette from non-earthly and/or non-magical entities, such as creatures or objects within range, are briefly revealed to you. This effect does not work on entities that are in total cover. i.e. closed rooms, closed off areas, magical spherical barriers, etc.
