Improved Grapple

(Oriental Adventures, page 63, DnD 3.0)

[General]

You are skilled in martial arts that emphasize holds and throws.

Prerequisite

Improved Unarmed Strike

Benefit

If you hit with an unarmed strike, you deal normal damage and can attempt to start a grapple as a free action without provoking an attack of opportunity. No initial touch attack is required. You can deal normal damage while grappling, rather than subdual damage, without suffering a penalty on your grapple check.

Normal

Characters without this feat make a melee touch attack to grab their opponent and provoke an attack of opportunity when doing so. They also suffer a --4 penalty on their grapple checks when trying to inflict normal damage in a grapple.
