Yes, each faction type to which there are 10.
Added custom armor for each of these types (First piecemeal, then didn't like the effect on the tech tree), but really now just 1 piece. Which means you have to make a piece of armor, 1 for each tier to which there are 3
Then put art on the armor to which there is up to 5 different categories on pieces of armor. A male / female version for each race and a Big fallen vs. Kingdom fallen type.
The art on the armor is really where the restrictions come in whether a unit can use the armor, the trick I learned from the henchman female mod and the executed functionality of a full suit from my sacrificial elemental mod.
If you take each of my mods, they are a tutorial on things I've learned in the xml functionality of fallen enchantress. Of course maybe I should write out the info of things I learned, but heavenfall has already trumped things I've done with my stuff. My advantage is most of my mods are small and have exactly 1 effect.
