Pinpoint Hearing
You hear echoes so clearly that even the reflected sound of your footsteps or the hum of a starship’s engine can disclose hidden secrets.
Preqrequisite
Echolocation Attack, Perception 9 ranks.
Benefit
You gain blindsense (sound) with a range of 30 feet. If you already have blindsense (sound or vibration), you instead gain blindsight (sound or vibration, matching your blindsense type). When using the Echolocation Attack feat, you extend the range of your granted blindsight by 30 feet.
