One battle per day as a quick action, you can call the spirits of your ancestors to fight alongside you. Your ancestors can't be hurt or affected by the creatures of this world.

At the end of each of your turns, if you are conscious, roll a d6. If you roll less than or equal to the escalation die, a member of your spirit warband strikes from the spirit realm into the world. Make a melee attack against a nearby enemy as if you were making the attack yourself, using any talents, feats, or magic items as you see fit. This attack doesn't take any of your actions.
