Yeah, I've only been able to not open one of those piles, and it was in rental's fortress. I found the Slith dealer, but he only had two energy herbs to sell, and I need about thirty... But, yeah, I always open those piles and pick the herbs up.
Hey all. I tried to search this but it didn't work. I know I've seen someone who sells herbs in a city, but I can't find the guy. I think he was a slith. I just found the guy who made knowledge brews, but ran out of energetic herbs. Thanks in advance!
