FALLING STAR STRIKE [Eastern Races, Combat, Martial]

     You have mastered the art of striking a nerve that blinds a
humanoid opponent.
Prerequisite: Stunning Fist, Wis 17+, BAB +4.

Benefit: Against a humanoid opponent, you can make an
unarmed attack that has a chance of blinding 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 blinded for 1 round per level you possess.  In addition to the obvious effects, a blinded creature suffers a 50% miss chance in combat (all opponents have full concealment), loses any Dexterity bonus to AC, grants a +2 bonus on attackers’ attack rolls (they are effectively invisible), moves at half speed, and suffers a –4 penalty on most Strength- and Dexterity-based skills.
