CHOKE HOLD [Combat, Martial]

    You have learned the correct way to apply pressure to render an opponent unconscious.
Prerequisites: Improved Grapple, Stunning Fist.
Benefit: If you pin your opponent while grappling and
maintain the pin for 1 full round, at the end of the round
your opponent must make a Fortitude saving throw (DC 10 +
1/2 your level + your Wisdom modifier).  If the saving throw
fails, your opponent falls unconscious for 1d3 rounds.
