King of Crusaders 3 Where is the fusion culture?

The fusion culture can be formed by the fusion of two cultures with a cultural acceptance of more than 40%, which requires the ruler to hold the earl collar belonging to both cultures at the same time.

The fusion culture can choose the traditions, cultural pillars and aesthetics of the two original cultures, and get all the innovations that have been discovered by the two original cultures, and the acceptance of the two original cultures will be 100%. The prestige cost of creating an integrated culture is determined by mutual cultural acceptance. The higher the cultural acceptance, the more Earle leaders will transform into integrated culture when creating culture.
