Holy Blood

Holy blood is a stat feature that is unique to Fire Emblem: Seisen no Keifu, and it affect certain stat growths and determines which holy weapon that character is allowed to wield. In-game holy blood is said to be shown by a special mark, unique for each crusader; as Diadora was acknowledged for having major Naga blood by a mark on her forehead, normally hidden by her circlet.

Holy Blood is split into two types: Minor blood and Major blood. These two blood type are further slipt into 13 different types based on each of the Twelve Crusaders, plus Loptous: Baldo, Odo, Hezul, Noba, Dain, Neir, Ulir, Blagi, Fala, Tordo, Holsety, Naga and Loptous. All have different affects on stat growth. It is not fully understood how holy blood is passed on to children, especially how major blood is only given to certain children.

Holy blood is displayed on a large circle in a character's info page. This circle is split into tweleve equal parts, with a thirteenth part as a smaller circle in the center. Each part has an open small circle with a crusader's name next to it.

- Minor blood is indicated by a small, blue circle. It raises a character's weapon rank by one level in their crusader's weapon type.

- Major blood is indicated by the same blue circle, but this time it's glowing wildly. It doubles Holy Blood growth bonuses and raises a character's weapon rank to * rank in their crusader's weapon type. They can also equip the holy weapon of their lineage.

- Loptous blood is indicated by a purple circle, that is located in the center part.

Characters in the first generation can pass their own holy blood on to their children in the second generation, giving the player limited contol over which second generation charcter can wield which holy weapon.
