I acknowledge your enthusiasm, WraithLord, and I really would want this to work with 3.10, but it seems futile. If the solution which has been applied to the ModsOverEurope game works like intended then we can use the same thing over here.
The insane def in "Stigian Corruption" mod represents spirit armor, thats not a typo. Recently I had to lower the prices for the nations commanders, since the AI was incapable of playing this nation. The nation seems highly overpowered but it has vulnerabilities (ex. Nephilim are high cost and 0 protection).
