Expert Hearing
Prerequisites: 8 HD
Benefit: Every round, you may make a listen check, DC 20+2 for every creature within a ten foot radius. If you succeed, you can use your hearing to “see,” as though with radar, everything within that radius. With a DC 30+3 for every creature within a twenty foot radius, you may increase the radius to twenty feet. You must choose either the ten foot radius or the twenty foot radius before making the roll. If you make this check, you can even detect invisible creatures, and they are considered to not have concealment anymore. Every round you must make a new check. Another creature may make a move silently check, DC your result on the listen roll, to not be picked up by this ability.
