Commanders may also be assigned to battalions within the army (in the Reorganise Army view).
A Chinese strategist who is your courtier or vassal will randomly teach Chinese leadership traits to your commanders. In the future I will do my best to keep Mercenary Commander updated and functioning with new patches to both CK2 and Dark World, but I will likely depend on users to help me identify issues. Also, only characters with a title higher than a baron may become commanders (unless there's not enough counts/dukes/kings in the empire to fill all commander slots). The following lifestyle traits have commander modifiers: Commanders may be wounded, maimed, made incapable, or killed during battle. Lifestyle event chains will not trigger for characters who already have a lifestyle trait. With multiple family murders, only the worst trait will be retained. Courtiers of Holy Orders and Mercenaries may also be assigned as flank leaders if part of their liege's troops are in the army, even if they do not have the commander title. The traits considered 'inappropriate' depend on religion. A trait that has opposites (functionally including different levels of the same characteristic) cannot be had simultaneously with them.
Some methods of religious conversion have a chance to leave characters with sympathy for their former religious group.
