Greater Ironclad Reactions (Armor Mastery)

You are able to quickly react to attacks.

Prerequisite(s): Combat Reflexes, Ironclad Reactions, Base attack bonus +11 or fighter level 8th, armor training class feature, proficiency with medium armor.

Benefit(s): You can use Ironclad Reactions more than once per round, but not more than once for each act you take that provokes an attack of opportunity. Each 5-foot step you take still counts as expending one use of an attack of opportunity.
