An actual city finds guide that is helpful, have a R+ for that
Might be worth adding too that each merit upgrade on awareness adds roughly +7% to your item spawn rates, city find rates aren't quite the same some might argue as higher awareness now DOES improve what quality of items you find too.
The pie chart might be a bit dated though, I'm yet to see any cash finds either.
I found that post from Ched to be frustratingly vague, personally. Couldn't quite decide whether it meant +70% to item finds or ched was trying to estimate how much higher gains you would get, factoring in better quality of item, considering the preceeding statement was confirming awareness meant better items.
Or whether he meant merits add 70% to the base rate or increase by 70% of the base rate, e.g. if the base rate is, let's say 10%, whether it would be 80% with 10/10 merits or 17%.
Regardless, I have tentatively threw some merits on awareness because I'm trying to be optimistic about this.
