What's Going On In The Mill?

Use your Redcap Soup to disguise yourself as a redcap. Find the redcaps in the room upstairs. Finish parleying with them before the potion runs out. It will last 15 minutes. Return to Hubert with your discoveries. - Redcaps Questioned (0/3)

"It may not be a good idea for you to actually go into the mill," mulls Hubert. "There are many threats there, not all of which we can anticipate. We also don't know if this will work on the smarter redcaps. But with this potion in our hands, I have another idea." "I happen to know that there are some redcaps lurking upstairs in one of the bedrooms. Go to them in this disguise and see what you can find out about what's been happening in the mill." SPOILER: Drink the potion and then go uptsairs in the inn. They will appear in the empty room after you drink the potion.
