One catch from a Reddit sub noted that I had goofed when rebalancing the difficulty.
I had intended to lower the needed Proof to 3, but another Redditor suggested gaining +1 Proof as well as +1 Danger when you roll a duplicate, which is probably more flavorful.
If you tackle this game, try it out and let me know which way you'd prefer and I'll get the PDF updated along with updated phrasing on the duplicate rolls if improved wording can be decided on.
