At the beggining this rebalance mod of mod will requier to be more skillfully, yet each upgrade will be noticeable and you will see it and feel it. When you get to the point of upgrading gold gain, the upgrade possibilities will sky-rocket, but also the challanges you will be able to withstand. The base premisa of the game where ideal is one to two hit base enemies will remain but even with all this the top tier enemies will still be hard to kill. The maxed values of skills after this extension can give you huge power which is why about half of them get lowered from 10% values to 1% values but still with massive overdrive effects if maxed.
