Size-Specific (Quality)

A Size-Specific weapon is only usable against a creature of the same size as the weapon. Thus, a size medium weapon may only be used against a size-medium creature. Attempting to use the weapon against an opponent who is incorrectly sized inflicts a -4 penalty to all rolls pertaining to the weapon's attacks and abilities. Creatures two or more size categories different than the weapon cannot be affected by the weapon at all.
