You have read the texts of the perfect way, and know how identify to your enemies' weak spot.
Benefit: You gain a +2 insight bonus on Knowledge checks made to identify creatures, including the one Kirin Style allows. While using Kirin Style against a creature you have identified using that feat, as a swift action after you have hit a creature with a melee or ranged attack, you can add twice your Intelligence modifier in damage (minimum 2).
Essentia: You do +2 Damage / Essentia against creature from your Kirin Style.
