Choose one type of weapon for which you have already taken Weapon Focus. You can also choose unarmed strike or grapple (or ray, if you are a spellcaster) as your weapon for purposes of this feat.

Prerequisites:Proficiency with selected weapon, Weapon Focus with selected weapon, warrior level 8th. 

Benefit:You gain a +1 bonus on all attack rolls with the selected weapon. This bonus stacks with other bonuses on attack rolls, including the one from Weapon Focus. 

Special:You can take Greater Weapon Focus multiple times. Its effects do not stack. Each time, it applies to a new type of weapon. Warriors must have Greater Weapon Focus with a given weapon to take Greater Weapon Specialization for that weapon. Warriors can select Greater Weapon Focus as one of their warrior bonus feats.
