Tested this at ~500 corruption, and gold was the same as I was getting pre patch. It doesn’t look like gold is scaling anywhere else either, but I didn’t have the data from before to quantify it, so I can’t be as sure.
Edit: Forgot an additional detail. I tested this with both preexisting gold reward echoes from before patch and also with new ones after resetting the web with Shade. They gave similar amounts.
I was watching for this myself and I am not sure if I was seeing things but it seemed that gold FROM MOBS increased a little around 150 corruption (havent got real figures because I never recorded pre 0.8.5 gold values), BUT at 350+ I am not seeing any substantial/noticeable gold value increase over what I am getting at 150 corruption from mobs.
I have not specifically compared gold chest values but again, it seems like there is no real substantial difference based on corruption.
Honestly tho, this is a gut feeling for me because I havent played enough to have any real data to tell if what I am seeing is true or not…
