Evasive Reflexes

 
Prerequisite(s): Dex 13+.
 
Benefit: When an opponent gives you a chance to make an attack of opportunity, you can instead immediately take a 5-foot step.
 
Special: Evasive Reflexes can be used in place of Combat Reflexes to qualify for a feat, prestige class, or other special ability. You can take both this feat and Combat Reflexes.
