FREEZING THE LIFEBLOOD [Eastern Races, Combat, Martial]

    You can paralyze a humanoid opponent with an unarmed attack.
Prerequisite: Stunning Fist, Wis 17+, BAB +5.
Benefit: Against a humanoid opponent, you can make an
unarmed attack that deals no damage, but has a chance of paralyzing your target.  If your attack is successful, your target must attempt a Fortitude saving throw (DC 10 + 1/2 your level + your Wisdom modifier).  If the target fails this saving throw, he is paralyzed for 1d4+1 rounds.  A paralyzed character stands rigid and helpless, unable to move or act physically.  He has effective Strength and Dexterity scores of 0 but may take purely mental actions.
