This should effect all spawned ritual forces (including forces at AI rituals). There are 5 different versions of this mod - one for each diffucultiy. Spawned armies will match that difficulty - no matter what difficulty you actually play.

does this mod affect the spawned ritual forces for the AI? I was playing a close skaven campaign and i noticed when the vortex forces spawned for the first half of the final ritual they were at half strength, and for the last half of the final riture they vortex forces spawned as a single chaos army with only 10 units and lvl 15 warlord. does any one know if this mod will change it so the Enemy AI will face the same amount of forces as the human player during the final ritual?
