Improved Low Blow

Mobility (PH) , Low Blow (Rac) , base attack bonus +4,

Using the Low Blow feat does not provoke an attack of opportunity when you move into an opponent’s square to perform the attack.

A character with the Low Blow feat may enter an adjacent opponent’s square to make a single attack, then return to his own square. The opponent is considered flat-footed against the attack, but the character is subject to an attack of opportunity.

You are especially good at using the Low Blow feat.
