Contrary to its name, Goatskin isn't a literal goat hide in Kingdom Come: Deliverance 2. He's a crucial character you must locate during the "Into the Underworld" main quest in Kuttenberg. Katherine will direct you to the inn, but finding him involves some detective work. Here's a simpler approach:
Goatskin hides in a barn above the Black Horse tavern. Access the barn behind the tailor's shop and ascend the ladder. Remember, this is a private area, so stealth is key.
Once upstairs, drop into the courtyard, climb onto the carriage, and enter the adjacent barn through a window. Climb to the top floor – Goatskin will be there. This strategy only works during the daytime; he changes locations at night. Saving your game before interacting with him is advisable, as successful dialogue checks are needed to avoid hefty bribes (150 groschen initially, rising to 500 groschen upon failure).
Failing skill checks will significantly increase the cost to progress the quest. If you're unsure about your skills, the 150 groschen bribe is a safer bet.
