Specialists, though not called that in game, are created by clicking a square being worked in the city screen. The citizen is removed from working that square, and becomes an Entertainer by default. He can then be clicked again to change him to a Taxman or a Scientist. File:Specialists (Civ1).png * An Entertainer makes luxuries, represented by diamonds or gems, which make citizens happy. * A Taxman increases tax revenue generated by the city. * A Scientist increases light bulb production. * Taxmen and Scientists cannot be made until the city is at least 5 in size.
