Melee Evasion

 
Prerequisite(s): Combat Expertise, Dodge Dex 13+, Int 13+.
 
Benefit: While fighting defensively, you can attempt to negate a single attack made by the target of your Dodge feat. If this opponent attacks you, use an immediate action to make a d20 roll modifi ed by your highest base attack bonus. The result is used as your normal AC and touch AC against that single, specifi c attack from your opponent. You cannot use this feat if your Dexterity bonus to AC does not apply against your opponent's attack.
 
Special: A fighter can select Melee Evasion as one of his fighter bonus feats.
