my most recent idea is that High perception should be required to spot tiny items like bullets/berries/ batteries etc at a distance. you can still manually search a square with the ‘x’ key, but i think you should have to have at least 11 perception to be able to spot a single bullet casing from 15 tiles away for example.
or you should also be able to see them regardless if you are in an adjacent tile.
been awake for 36 hours now, so maybe this makes more sense to me than I’ve typed out…
