IMPROVED GRAPPLE [Combat, Martial]

    You are skilled in martial arts that emphasize holds and throws.
Prerequisite: Improved Unarmed Strike.
Benefit: If you hit with an unarmed strike, you deal normal
damage and can attempt to start a grapple as a free action without provoking an attack of opportunity.  No initial touch attack is required.  You can deal normal damage while grappling, rather than subdual damage, without suffering a penalty on your grapple check.
Normal: Characters without this feat make a melee touch
attack to grab their opponent and provoke an attack of opportunity when doing so. They also suffer a –4 penalty on their grapple checks when trying to inflict normal damage in a grapple.
