Improved Critical (dart)

Type of Feat: General Prerequisite: Proficiency with the chosen weapon, base attack bonus +8 or higher. 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. 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. Special: Halflings and Gnomes are small creatures and as such they can never use the following large weapons - dire mace, double bladed sword, doubleaxe, greataxe, greatsword, halberd, heavy flail, and scythe.
