I finally figured out how to extract the files in this game lol. I made a mod for some things that really improve the immersion. The brothers no longer pussy out once they've been beaten ONE time. Leading to some interesting effects if a girl gets captured at random forts. Not only that, but you have to push the brother out of each fort down the line if he has enough health to fight against you. In essence I removed the if statement checking that it's their castle under attack and replaced it with an HP check over 5k.
I set the cannon unit to 280 destruction(same value as ram... which is a way cheaper unit that has 4 times the speed). Original value was 62. The overall effect in game was actually pretty effective. Marion bombarded my defense with 2 shots that actually rendered my turret a lot less effective during the later enemies. The first shot being her cannon and the second being her massive bomb ability. She still went down pretty fast, but at least she contributed to their assault in a meaningful way instead of her usual self of dying pathetically.
The next thing I'm working on is figuring out how to stop monsters from disappearing from the map so fast. It's really weird how Hippia starts out with this massive wave of deadly monsters in the beginning of the game and almost half of them die -permanently- after being killed one time(usually in that first assault). Very strange reverse difficulty curve there as your characters get OHKO attacks and not a whole lot to use them on later in the game. So it's like you survive that initial OP onslaught and then the game just rolls over for you lol. I get the feeling the reason why this happens is that ai checks for hiring generals from the "wanderer" pool only 20%(30% on black difficulty) of the time. The game seems to randomly decide to delete "wanderers" by sending them to the "Eastern Lands" once they are not hired, but I can't figure out at what point it has decided they took too long to get hired. I know how to stop the monsters from going to the wanderer pool. I just have to assign them to the nation of hippia and they never permanently die, but that just sounds tedious.
