Saving Shield

Saving Shield (Combat)
You deflect attacks that could mean your ally’s death.
Benefits: Whenever an adjacent ally is the target of an attack, you can, as an immediate action, grant that adjacent ally a +2 shield bonus to AC. You must be wielding a light shield, heavy shield, or tower shield to use this feat.

---

(BAB +4): You may use this ability twice a round, despite the normal limits on the use of immediate actions.
