I only need 8 underbrush to finish one of the harbinger quests. The problem is the underbrush on the market and on branches is way too expensive. I would be willing to do a combination of items and SB or a trade of some sort. Any of the cubs in my den are up for trade, some of them have mutations. I have 27 locust wings, pennyroyal, and some other miscellaneous items. Just tell me what you're looking for and I'll try to make it happen.
