Type of Feat: General
Prerequisite: Proficiency with the chosen weapon, BAB +8
Required For: Overwhelming Critical
Specifics: Combat ability doubles the critical Threat range with a given weapon. A longsword that normally threatens a critical on a roll of 19-20 would now threaten a critical on a roll of 17-20. A weapon that would normally threaten a critical on a roll of 20 (ie only 1 out of 20) now threatens a critical on a roll of 19-20 (ie now 2 out of 20).
Use: Automatic. The threat range of a Keen weapon is already doubled, increasing to triple with this feat. This feat can be selected multiple times, applying to a new weapon category each time.
