Not sure where you got the idea of saving throws from but Fextralife and a few others have played the dark urge well into act 2 and didn't mention it.
Found the clip which I have the information from. It is from a Youtub/Twitch ..Person named JesseCox (No idea why the URL sounds so weird).
He says that he talked with Swen Vincke about this topic (at PfH if memory serves). The Clip is 45 seconds long, if you are interested.
EDIT: Sorry for the Reddit link, but the direct Twitch-link creates an embedded video that jsut doesn't work.

The bottom line is that what I have seen and what I have heard about rewards does not really interest me. But considering some (probably niche) stuff that I expect for myself, I am happy that you are looking forward to it!
When I have a better idea on how to say what I mean, I may try explaining it again. ;-)
