Demigod-War born

One of your ancestors is a god of war, and you've inherited some of their power. While some of these these Demigods, who some refer to as "Blood-stained" rush into battle without thinking, some asses their surroundings before making a move. these demigods are ideal soldiers for some armies. However, the Blood-Stained are rare, as gods of war tend to fight alone. when you select this feat, you cant choose another feat with the name "Demigod" in it. in addition, choose one deity from the War domain.
