As soon as a Noble is born, you can assign their Role. This is a requirement for maturing a Noble baby and assigned roles are permanent. The chosen role will determine the pool of available traits for your Noble, their available army slots, their available army types and of course their talents.

Every Role has a specific set of equipment that can be crafted, that compliments each respective Noble Role accordingly (e.g. For Traders you get increased Trading speed & more). Noble equipment comes in different rarities (Common, Uncommon and Rare) and can be crafted in the Blacksmith.

Not all rarities are available immediately. They can be unlocked through research in the "Nobles" tree in the Academy!
