Ways to increase Critical hit multiplier

 * Monks that choose Master of Stone or Grandmaster of Stone stances gain +1 to their threat range when fighting unarmed, effectively now receiving Improved Critical threat range doubling to 19-20 while in the stance. Mountain stance III/IV threat ranges do not stack with Improved Critical, but do stack when combined with Fists of Iron used for the Earth-Earth-Earth finisher for a x5 threat range, unarmed, on a roll of 19 or 20.
 * Barbarian Frenzied
 * Paladin KotC smite
