I'm going to grab some beer and chips.
I won't interfere too much with the gameplay, but I'll give one piece of advice: read the notes after the list of non-discoverable artifacts, because many people seem to have missed them.
Regarding protection against external influences: I didn't make an exception for checks and left it as is. It's not that big of a probability. I'll just clarify (in the same place, in the notes after the list of non-discoverable artifacts) that all non-discoverable artifacts aimed at that goal (Redkin on a walk, a genie in the palace, Kamoyedov's ultimate ability) are displayed as usual.
To sell my soul
