Clairaudience

for each additional level
Skill: Clairvoyance (IQ/Hard).
You can project your sense of hearing to a distance from your
body. This uses the same rules and range as Clairvoyance
(below), except that there will rarely be a need to change facing.
* If you have the Clairvoyance ability (below), the cost for
Clairaudience becomes a flat 5 points. Use the rules and level
for Clairvoyance, as though you were also using the Audio
technique without incurring the FP cost, skill penalty, or any
other negative effects.
Statistics: Clairsentience (Clairaudience, -30%; ESP, -10%;
Fixed Range, -5%; Reduced Range 1/10, -30%) [13]. Further
levels remove Reduced Range and then add Increased Range,
one level at a time [+5/level]. Psis with Clairvoyance just
remove Clairvoyance from their Clairsentience [+5].
