BLINDSIGHT [Combat, Martial]

     You sense opponents in the darkness or when blind.
Prerequisite: Blind-Fight, Wis 19+, BAB +4.
Benefit: Using senses such as acute hearing and
sensitivity to vibrations you detect the location of
opponents who are no more than 5 feet away from you.  Invisibility and darkness are irrelevant, though you
cannot discern non-corporeal beings.  Except for the
decreased range, this feat is identical with the
exceptional ability blindsight defined in the Monster
Manual.
