Focused Sense
You can sharpen an imprecise sense to detect things with precision at closer range.
Preqrequisite
Blindsense.
Benefit
As a move action, you can gain blindsight (using the same sense as your blindsense) with a range equal to half that of your blindsense until the beginning of your next turn. You can use this ability with only one type of blindsense (such as sound or vibration) at a time.
