Piranha Strike (Feat)
You make a combination of quick strikes, sacrificing accuracy for multiple, minor wounds that prove exceptionally deadly.
Prerequisites: BAB +1, Weapon Finesse (Feat)
Unlocks: Furious Focus (Feat), Powerful Precision (Feat), Invincible Warrior (Feat)
Benefit: When wielding a light weapon (including weapons with the Finesse quality), you can choose to take a -1 penalty on all melee attack rolls and combat maneuver checks to gain a +2 bonus on all melee damage rolls. This bonus to damage is halved (-50%) if you are making an attack with an off-hand weapon or secondary natural weapon. When your base attack bonus reaches +4, and for every 4 points thereafter, the penalty increases by -1 and the bonus on damage rolls increases by +2. It is increased by 50% (+3) if you are using a two-handed Finesse weapon. You must choose to use this feat before the attack roll, and its effects last until your next turn. The bonus damage does not apply to touch attacks or effects that do not deal hit point damage. This feat cannot be used in conjunction with the Power Attack feat.
