Benefit: During your action, designate an ally within your reach. When you fight defensively or use Combat Expertise, your ally gains a natural armor bonus to AC equal to the dodge bonus you gain from fighting defensively or Combat Expertise. You can select a new ally on any action. Allies who move out of your reach lose this natural armor bonus.
