DESCRIPTION

This ability doubles the threat range of a weapon. Only piercing or slashing melee weapons can be keen. If you roll this special ability randomly for an inappropriate weapon, reroll. This benefit doesn't stack with any other effects that expand the threat range of a weapon (such as the keen edge spell or the Improved Critical feat).

CONSTRUCTION REQUIREMENTS
