Echolocation Attack

You have learned to use the echo of sonic attacks to locate unseen assailants.

Prerequisites: Perception as a class skill.

Benefit: When you take an action that deals sonic damage, as a move action you can grant yourself blindsense (sound) with a range of 30 feet until the end of your next turn. If you have blindsense (sound or vibration), you can instead grant yourself blindsight (sound or vibration, to match your blindsense) with a range of 30 feet or a range equal to your blindsense (whichever is shorter) until the end of your next turn.
