This tutorial is not about the actual process of creating specialist for Civ4, but about the yields that should be allocated to them to give them the same level of impact as the other specialists. For calculating how much yields a specialist should provide it helps to imaging that each specialist has a certain amount of skillpoint (SP) that can be converted into certain yields. A normal specialist has 12 SP and a great specialist has 18 SP. With these SP, you can go shopping now: = 6 SP = 4 SP = 4 SP (only a recommendation) = 2 SP = 2 SP = 1 SP = 1 SP = 2 SP Further, if you are using Supercheese's Specialist Enhancements I would recommend: = 6 SP = 6 SP So for example, if you want to make an entertainer, you could give him - 1 => -6 SP + 2 => +4 SP + 2 => +2 SP + 1 => +6 SP + 3 => +6 SP Altogether 12 SP. And that's it. I would further recommend to give normal specialists always 3 to make them consistent with the other specialists. If you are interested in the my math that is behind these numbers, see the next post.
