You are skilled at grappling and fighting while unarmed.

Benefit: You are considered to be armed even when unarmed - you do not provoke attacks of opportunity when you attack foes while unarmed. Your unarmed strikes now deal 1d6 damage if you are medium sized or 1d4 damage if you are small sized, and you can deal lethal or nonlethal damage, at your choice.

A character with this feat may attack with fists, elbows, knees, and feet. This means that a character with this feat may make unarmed strikes with his hands full.

You do not provoke an attack of opportunity when performing a grapple or throw combat maneuver. In addition, you receive a +2 bonus on checks made to grapple or throw a foe. You also receive a +2 bonus to your Combat Maneuver Defense whenever an opponent tries to grapple or throw you.

Normal: Without this feat, you are considered unarmed when attacking with an unarmed strike, you can deal only nonlethal damage with such an attack and may make attacks only with your fists. You provoke an attack of opportunity when performing a grapple or throw combat maneuver.
