Description: Your senses are as keen as the bat’s.

Prerequisites: Ability to use wild shape to become a dire bat

You gain the extraordinary ability blindsight which operates regardless of your form. Like the dire bat, you emit high-frequency sounds, inaudible to most creatures, as a form of “sonar” that allows you to locate objects and creatures within 120 feet. Since this ability relies on hearing, any circumstance that deprives you of that sense also negates your blindsight.
