Bodyguard (Feat)

Your swift strikes ward off enemies attacking nearby allies.

Prerequisites: Combat Reflexes (Feat)

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 must make a to-hit roll against the attacking opponent, and if it succeeds, instead of dealing damage, you aid your ally with a +2 bonus to their AC, using up your attack of opportunity. You may not use the aid another action to improve your ally's attack roll with this attack.

Normal: Aid another is a standard action.
