Filthy Outburst

 
Prerequisite(s): Dark Speech, Base Will Save 7+
 
Benefit: As a swift action, you loose a blistering torrent of foul curses and wicked insults in the Dark Speech. All living creatures within 60 feet that can hear you must succeed on Will saves (DC 10 + 1/2 your character level + your Cha modifi er) or become deafened for a number of rounds equal to your character level. As long as an affected creature is deafened, it takes a —4 profane penalty on saving throws to resist evil spells or spell-like abilities. Whenever you use Dark Speech in this manner, you take 1d6 points of Charisma damage.
 
Special: If you cannot take ability damage, you cannot select this feat.
