Well just in theory You could change the apropriate numbers in party.txt and have them level every level if set to 1 but it would require to start a new game for this. I usually set req min level to 5 and level every to 1 for all applicable ones. The game begins to be hilariously op pretty damn quick. It is possible to waste metzger with just me and slulik (before VC trip) and slavers camp with me sulik and vic also before VC trip. Though i fiddle with every lock that i encounter before slave camp in order to gain more xp.
