I have managed to change my weapons stats so that I do a max amount of damage per hit (one hit kill basically) AND every melee hit heals me to max... so this is basically god mode (no gravity is still a thing lol).
If you want, here's my main weapon (katana) original value and the line below is the modded data (FF FF for max amount; 65535). the game is boring once you have this tbh but still, if you want to rush it, have fun.
I'm still working on the proficiency data because that grind is... too much for me.
I'll update asap.
