Weapon Specialization, Greater (Feat)
Greater Weapon Specialization
Choose one type of weapon (including unarmed strike or grapple) for which you possess the Weapon Specialization feat. Your attacks with the chosen weapon are more devastating than normal.
Prerequisites: Fighter 12, Weapon Focus and Greater Weapon Focus and Weapon Specialization with chosen weapon
Benefit: You add +1 to the base damage on all damage rolls you make using the selected weapon. Base damage improves along with weapon damage at 8th, 15th, 22nd and 29th, meaning that this is a +5 bonus at 29th level. Base damage is always multiplied on a critical hit. This bonus stacks with the base damage increase provided by Weapon Specialization.
Special: You can gain Greater Weapon Specialization multiple times. Its effects do not stack. Each time you take the feat, it applies to a new type of weapon.
