Weapon Finesse

Weapon finesse allows the character to use his dexterity modifier instead of the strength modifier when making melee attack rolls with light weapons, rapiers, and unarmed strikes. The highest of the strength and dexerity modifiers will be used for attack rolls with qualifying weapons. The strength modifier is still used as a bonus to the damage roll, however.

Prerequisite: Base attack bonus of +1 or higher

The following weapon types benefit from Weapon Finesse: Dagger, Handaxe, Kama, Kukri, Light mace, Light pick, Rapier, Short sword, Sickle and Unarmed. Note in particular that as of May 2006, light hammers do not benefit from weapon finesse, but this is a known bug that will be fixed in a future update.

A fighter may select this as one of his fighter bonus feats.
