I'm afraid after the ritual those stats will all go to 1!
There were balance changes made that affect the later stuff in Ego Draconis I think. One example I can think of is in the original version a fight with a demon in Dragon form was really easy and now it's really difficult. However in other parts it was made easier and I think allows you to level up faster than the original. Nightmare difficulty was added too. Old build guides will mostly still be okay anyway.
