Blood Vengeance

Half-orc or orc, nonlawful.

Whenever one of your allies is reduced to negative hit points or killed, you may enter a state similar to but less powerful than a barbarian's rage as a free action on your next turn. If you have the rage class feature and are already raging, your morale bonuses to Strength and Constitution increase by +2 for the duration of your rage. If you do not have the rage class feature, or you have no more rage rounds left, this weaker rage gives you all the benefits and penalties
