Blindsense

Blindsense is a powerful form of hearing that allows a creature to determine the shape of its environment through sound waves (i.e. echolocation). It works in all directions simultaneously, so it can be very difficult to sneak up on a creature with blindsense. Blindsense can be used to establish Line of Perception and grants a +2 Racial bonus to Listen checks and Awareness.

Blindsense is an Auditory sense.
