Just played the game again to try the new content after the festival and tried a 100% pure run, normal difficulty no NG+. I really like the new content a lot.
Regarding the difficulty, It was pretty easy until the festival but after that the difficulty went up quite a lot I would say and I had to get mental changes and I was forced (or maybe not???) to use SK to kill the magistrates worshippers when they were 2 or more. But this might be because there is not enough new skills or just chests giving gold, blessed water etc for a 100% pure run and anyway it might be even better if a 100% pure run is not possible.
I have a few suggestions too:
1) It would be nice if you could put somewhere the exact mathematical formulas of the skills damages, how much damage do critical hits compared to normal attacks, what does LUCK do exactly in terms of percentages and other things like that. Maybe you can expand the books in the adventurer guild or add a special item which allows us to see those numbers in a single place for weird people like me without bothering normal people with tons of numbers and formulas.
2) The percentage of enemy "weakness" or "resistance" to elements in the bestiary. Not sure if it those percentages are the same for all enemies but it would be good if not.
3) I think you should add the "bubble state" ( the one water mages give you) in the list of common states in the adventurer guild.
