Crippling Finesse (Combat)

Your precision is more important than your strength when you strike vital areas.

Prerequisite(s): Dex 15, Weapon Focus (light or one-handed piercing weapon), 5th-level duelist

Benefit: When you make a critical hit using a light or one-handed piercing weapon for which you have the Weapon Focus feat, you can use your Dexterity modifier in place of your Strength modifier when calculating the attack’s damage.
