Description: You know how to wield the eagle's claw with deadly speed.

Prerequisites: DEX 15, Eagle's Claw Proficiency

You can get one extra attack per round with an eagle's claw. The attack is at your highest base attack bonus, but each attack you make in that round (the extra one and the normal ones) takes a -2 penalty. You must take a full attack action to use this feat.
