Fencing Grace

Combat

Your dashing style and fluid rapier forms allow you to use agility rather than brute force to fell your foes.

Prerequisite: Dex 13, Weapon Finesse, Weapon Focus (rapier).

Benefit: When wielding a rapier one-handed, you can add your Dexterity modifier instead of your Strength modifier to that weapon’s damage. The rapier must be one appropriate for your size. In addition, if you have the panache class feature, you gain a +2 bonus to CMD against attempts to disarm you of your rapier while you have at least 1 panache point.
