Fu: X, Shot: 0, Maximum picks: 1
You can feel what is about you in the dark. This feeling is not sight, rather it is a combination of hearing and an extremely fine sense of vibration. It is always active, with no need to spend Fu or Shots to activate it.
You can sense movement along a cave floor you are standing on out to five meters times your Perception, and sense walls, objects and people standing still within your Perception meters. This sense is about as effective as sight, but can work around corners and in complete darkness. It allows you to fight and work at full effect.
By spending an action and Fu, you can amplify your sensitivity, adding the amount of Fu spent to your Perception for a single check.
This sense does not work well on the surface, where wind and the multitude of living, moving things confuse you to no end.
This is a counterpart to ElfinSenses.
