Prerequisite: Dex 13, Dodge, Mobility.

Benefit: Whenever you score a critical hit with a melee attack, you can immediately make a 5-foot step as a free action, even if it’s not your turn (such as when you make a critical hit as an attack of opportunity). This does not count against your total movement for the round, nor against the number of 5-foot steps you can take.

Special: You can apply the effects of only one critical feat to a given critical hit unless you possess Critical Mastery.
