House Rules: Feats – Bodyguard

Your swift strikes ward off enemies attacking nearby allies.
    Prerequisites: Combat reflexes.
    Benefit: When an adjacent ally is attacked, you may use an attack of opportunity to attempt the aid another action to improve your ally’s AC. You may not use the aid another action to improve your ally’s attack roll with this attack.
    While using the aid another action to improve an adjacent ally’s AC, you can intercept a successful attack against that ally as an immediate action, taking full damage from that attack and any associated effects (bleed, poison, etc.). A creature cannot benefit from this feat more than once per attack.
    Normal: Aid another is a standard action.
