Can't say I've heard of such a patch but this game has the ability to be beaten at a very low level if you know how to abuse the system. easiest way is to devour/card the monsters you meet to have the gf's learn the skills to utilize the junction and conversion abilities. Then take those cards to make items/magic to enhance your characters. Heck I got a file where I played card games for 15 hours (one hour of story, just enough to get ifrit) so Whenever I wanna breeze through the game with OP characters and optimal weapons for everyone I can.
I know this game gets a lot of flak for it's unorthodox style of foraging for everything, including what you equip, but if taken enough time to understand how everything works you can literally control every aspect of your play-through and that's what keeps me coming back.
