dunno how exactly the spawn thing works but i know the mongols get more armies when they conquer certain regions, they get spawns when conquering most persian settlements till Baghdad, settlements they conquer afterwards dont grant them anything, or atleast shouldnt
if you wanna know exactly where you'd have to look into a file called "campaign_script" (\mods\SS6.3\data\world\maps\campaign\imperial_campaign)
