Description: You can bounce your weapon off one opponent to strike at another with the same throw.
Prerequisites: Blind-Fight, Point Blank Shot, Precise Shot, Improved Precise Shot, DEX 19, Base Attack Bonus +15
Once per round, when you successfully hit an opponent with a thrown weapon that deals bludgeoning damage, you may make an automatic second attack roll against a creature adjacent to that opponent. The second attack takes a -5 penalty. The first creature hit takes damage normally (including Strength modifier, sneak attack damage, and so on), while the second opponent takes 1/2 damage from the weapon + 1/2 your Strength modifier. Only one additional creature can be struck as a result of using this feat. You cannot sneak attack the second creature struck.
Special
: A fighter may select Ricochet as one of his fighter bonus feats.
