Improved Grapple [General]
You are skilled at grappling opponents.
Prerequisites: Dex 13, Improved Unarmed Strike.
Benefit: You do not provoke an attack or opportunity when you make a touch attack to start a grapple. You also gain a +4 bonus on all grapple checks, regardless of weather you started the grapple.
Normal: Without this feat, you provoke an attack of opportunity when you make a touch attack to start a grapple.
Special: A Monk may select Improved Grapple as a bonus feat at 1st level, even if she does not meet the prerequisites.
A fighter may select Improved Grapple as one of his fighter bonus feats (see page 38).
