Divine Omen is a faction mechanic of Dardania from a Total War Saga: Troy.
As a leader and a warrior, god-born Aeneas was always considered humble and pious. Having been instructed at a young age in the mystical ways, Aeneas believes he is able to read the omens sent by the gods and interpret divine orders that he must carry out in their name. His people could realy rely on him to seek out the will of the divine and earn the favour of Olympus.
Calling upon the gods to reveal such omens take a few turns to become available. Reading the omens require moderate amounts of precious resources which are spent to prepare for the ceremony. After the priests interpret the omens, the will of the gods is revealed in the form of three divine missions. Completing these missions each will reward the player with divine favour of a certain god.
