The Emerald Nightmare: Felwort Mastery

I have a theory on how we can better harvest this felwort, ‹name›. You see, sometimes in order to understand how something comes into being, you have to work backwards. I've recently heard of the corruption of one of our greatest gods, Cenarius. I have no doubt the same corruption that lives in these herbs also resides within him now. If you were able to cleanse that corruption, find a way to understand how it works and remove it, I think we can apply that to how we harvest these herbs.
