I am playing the casse and saw that in custom battles i can recruit quite a lot of goidilic units and midlander spearmen. What do i have to build to get them?

P.S.: This mod is absolutly awesome. I am in love with your trait sytem which gives the gameplay so much more depth. Battles seem more challenging too. I still win almost all of them but at least losses are now at 1:4 and not 1:10 ratio. Thans for your dedication and hard work.
