Honestly, I thought the prices on the scrolls were fine and the scroll of wealth already increased coin rewards pretty significantly. If anything, instead of changing the scroll of wealth I would look at optimizing some of the other scrolls like scroll of accuracy/speed.
I'm happy that the black ore resource gain was increased though - it's really a pain to farm 200 of it if you wanna create The One Ring and Buttplug.
One major annoying thing though is how my save file doesn't recognize the huge purchases I've made with Selim in regards to his affinity scene: I purchased the Dragon Sword already and his affinity is like, tiny.
