Greater Critical

Greater Critical (General)
Select one weapon that you have already applied the Improved Critical feat to. You have learned to wield that weapon with such skill as to inflict devastating amounts of damage on a regular basis.
Prerequisites: Improved Critical, base attack bonus +16.
Benefit: When using the weapon you selected, your threat range is tripled. This super sedes the doubling provided by the Improved Critical feat.
Special: This feat can be gained multiple times. The effectsdo not stack. Each time you take the feat, it applies to a new weapon. A character who has seven or more levels of thebarbarian class may not select this feat. If a character with this feat ever gains seven or more levels in the barbarianclass, he immediately and permanently loses this feat.
