Benefit

If your attack with an unarmed strike or a light or one-handed melee weapon hits, the strike deals normal damage and you can attempt to start a grapple as a free action; no initial touch attack is required. If you succeed in starting the grapple, you must drop your onehanded weapon, but if you started the grapple with a light weapon, you can use it in each round to make an attack against the creature you are grappling without taking the normal -4 penalty on the attack roll. If you initiated the grapple while armed, however, you cannot make additional grapple checks to deal damage during the round in which you use this feat. You have the option to conduct the grapple normally, or you may hold a creature one or more sizes smaller than you with your off hand. If you choose to do the latter, you take a -20 penalty on grapple checks against that creature and you cannot deal damage with your grapple checks, but you are not considered grappled yourself. You don't lose your Dexterity bonus to AC, you still threaten an area, and you can use remaining attacks against other opponents. While maintaining this latter type of hold, you can move normally (possibly carrying your opponent away), provided you can drag the opponent's weight.
