have you considered adding a mechanic where mid battle a heroine can spend a turn or 2 with a hilichurl/friendly unit and gain buffs from it? maybe change what buffs depending on the unit type.
maybe it could provide a moral boost to all friendly units giving them maybe a speed buff or a typical damage buff? maybe dmg resistance or a buff based on what heroine or churl?
