Echolocation

For the duration, you make an audible "click" with your tongue once every minute, applying a -1d4 penalty  to any Stealth check you make for the spell's duration. During this time, you transform the "clicks" into a visualization of your surroundings, grating you blindsight out to a range of 60 feet. However, creatures and objects you can "see" appear in shades of gray.
