Everything was multiplied by 10 instead of 173 for some reason
Ah, that's because the effect is actually equal to prestige point^0.43. Meaning they double every time prestige grows by 5 times. Otherwise it's going to grow too fast (prestige is already a bit too fast).
sorry for the confusion! Right now the balancing is not well made. I’ll try to improve that and also make it more clear how prestige works.
