You are an expert at defending yourself and those around you.
Prerequisites
Combat Expertise, base attack bonus +4.
Benefit
While using this style, any time you use Combat Expertise to grant yourself a dodge bonus to AC, the dodge bonus is increased by 1.
In addition, when you use Combat Expertise or take the total defense action you can designate one ally that is in a space adjacent to you. That ally gains a circumstance bonus to AC equal to the bonus you granted yourself. If the ally is unconscious or helpless, this bonus is doubled. The ally loses the benefit if they are not adjacent to you, and the bonus lasts until the start of your next turn.
This circumstance bonus does not stack with with any dodge bonuses gained by that ally via their own use of Combat Expertise, fighting defensively, or taking the total defense action, nor does it stack with the bonus granted by another ally’s use of Guardian Angel Style.
