Hmmm....this could cause an issue ... but I will see If I can get it to work...They should both so exactly the same. The only difference is that for the Fake one, the ch.rank is NOT increased.
So you get the skill and ability points plus the HP increase from a normal level-up,
but as your actual level isn't increased and many enemies are generated based on your character level, you gain an unfair advantage over your enemies.
