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 who warns you about a hostile vagrant nearby.
Inside the barn's vicinity, you'll find a beggar NPC. He'll become aggressive if approached. 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 lootable items.
What to Do With the Door and Chest Keys?

The game provides no backstory for the Wandering Drunk. He might be a nod to a similar beggar from the first game, a character who lost everything and became a vagrant without further quests. It's plausible he simply lost his home and family, and the keys are merely narrative details.
Many NPCs in the game carry keys with unknown purposes. The Wandering Drunk's keys likely fall into this category.
