I have been trying to find a way to do this . It looks like there is no randomization. When I've run RMSS or rolemaster (the original) we could randomize the level there e were rules for it. I've got AutoHarp and it is a great program but I don't see a way to randomize it in it either. For example I want to send a group of orcs against a party. The only thing I can do is send a 1st level orc. that is the only thing it shows. Unless I want to level up that orc. which takes too long to be practical in a caompaign for a non improtant npc.
