Contrary to its name, Goatskin isn't a goat 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 a simpler method exists.
Goatskin resides in a barn near 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 advised.
From the barn's upper level, descend into a courtyard, climb onto the carriage, and enter another barn through a window. Locate Goatskin on the upper floor. This process must be completed during the day; Goatskin changes locations at night. Saving your game beforehand is recommended, as successful dialogue checks are necessary to avoid costly bribes (150 groschen initially, rising to 500 groschen upon failure).
Failing skill checks results in a hefty 500 groschen bribe. If you lack confidence in your skills, paying the initial 150 groschen is a viable alternative.
This concludes the guide to finding Goatskin in Kingdom Come: Deliverance 2. For further game tips, including romance options and optimal perk selections, consult The Escapist.
