In *Kingdom Come: Deliverance 2*, you'll encounter a diverse cast of NPCs, some friendly, some not so much. Determining their intentions isn't always straightforward. This guide focuses on the Wandering Drunk.
Kingdom Come: Deliverance 2 Wandering Drunk Location

The Wandering Drunk resides in an abandoned barn just north of Semine, slightly off the main roads. While riding north, you'll meet a herdsman warning you about a hostile vagrant nearby.
Inside the barn's vicinity, you'll find a beggar NPC. Approaching too closely will provoke a hostile response. Currently, there's no peaceful interaction; combat is unavoidable. Defeating him yields a gemstone ring, keys, and 2.7 groschen. The barn itself also contains additional lootable items.
What to Do With the Door and Chest Keys?

The game offers no clues regarding the Wandering Drunk's identity. He might be a nod to a similar beggar from the first game, a character who lost everything and became a vagrant without further quest involvement. It's plausible his keys belonged to a former home, included simply for narrative flavor.
Many NPCs in the game carry keys with unknown purposes upon looting or pickpocketing. The Wandering Drunk's keys likely fall into this category.
