A bit too much woundwart, the ratio could be toned down and perhaps upped for other herbs. This is the second summer season and there is barely anything save for woundwart.
Haunted woods dosnt grow any herbs, i know its.. haunted, but there's grass and trees that grows there, i dont see why herbs for potions wouldnt either.
Maybe if a herb picking skill was implemented, certain nodes would give out more herbs than just one.
