Defensive Throw
Prerequisite: Unarmed Strike >= 1, Master Grapple, Master Trip.
          OR: Martial Mastery, Master Grapple, Master Trip.
Benefit: When a humanoid foe swings at you and misses your Defense Class by 8 or more, and you are unarmed, you can execute a trip attack against that foe. This costs you one attack of opportunity for the round, but has no actual timecost for you.
Allows: Great Throw.
