You can summon the spirit of a great warrior ancestor and allow it to possess you, becoming a mighty warrior yourself. You gain a +4 enhancement bonus to Strength, Dexterity, and Constitution, and a +4 natural armor bonus to AC. Your base attack bonus while possessed equals your oracle level (which may give you additional attacks), and you gain the Improved Critical feat with a weapon of your choice. You can use this ability for 1 round for every 2 oracle levels you possess. This duration does not need to be consecutive, but it must be spent in 1-round increments. You must be at least 11th level to select this revelation.
