Attack bonus

Your attack bonus with weapons is a combination of:


 * Base attack bonus + ability modifier + weapon's enhancement bonus + other modifiers

Most melee weapons weapons use Strength for calculating attack bonus. With the Weapon Finesse feat, your attack bonus with a light melee weapon, a rapier, or unarmed uses Dexterity.

Ranged or thrown weapon use dexterity for calculating attack bonus. With the Brutal Throw feat, your attack bonus with thrown weapons (but NOT ranged weapons) uses strength.

Certain weapons use different abilities for calculating attack bonus (e.g., Epic Dynastic Falcata or Staff of Nat Gann).
