There's a number of newbie herbs out there that can be fully seen with 40 exp*per. Blueberries, nettles, taproot to name a few. It seems like a small thing, but without knowing to raise exp to 4, the world seems very barren for beginners. With it your minimap at least has a bit of character to it. I actually get 4 exp even on my suicide alts just so the world seems a bit less empty.
It seems to me like this should be something everyone gets so beginners can't make a simple mistake that makes the game empty and boring for them in their earliest moments. All of these forageables fully seen with 40 score should be fully seen with 10 score I feel.
