This cosmetic DLC adds in seven new models for units of a holy order in Christian nations. This is a good pack to get if you also own the Sons of Abraham DLC that changed how holy orders work and added new ones into the game. Holy orders can be created when certain conditions are met and with Sons of Abraham may also be operating independently. The new unit models all look good wielding different weapons, banners, and shields with the heraldry belonging to their order. The unit models themselves will not change depending on what holy order they belong to though, so you will not see anything like the spiked helmets of the Teutonic Order. This DLC is only cosmetic and will change nothing about the units except for their appearance on the world map.
