I am playing Heroes 7 on crushing/prolific difficulty and I find it a bit too easy because I literally win 4 or 5 fights and I"m already levelled up half of my wheel. Just winning one fight can level me up 5 times. I greatly prefer leveling up much more slow, so what I'd like to do is put in a fractional modifier on XP gains so that I gain XP much more slowly (along with the AI). I'm messing around in the editor and looking through cookedPC files but completely unsure how to do this. I'd hate to modify the XP gain of every single creature, it would be far easier to just have a global modifier on hero levelling.

Anyone know how? Thanks so much!
