DESCRIPTION
Only piercing or slashing melee weapons can be keen.
This ability doubles the threat range of a weapon. 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 spell or the Improved Critical feat).
