Caste System (Civ4)

Caste System is a labor civic in Civilization IV.
== Strategy ==
Caste System allows you to assign unlimited Artist, Scientist, and Merchant specialists in your cities. This notably does not include Engineers and Priests, the specialists who add hammers to city production - these still require their prerequisite buildings.
In Beyond the Sword, the civic is buffed by an additional effect giving +1 from worked Workshops.
