Encountering a diverse cast of NPCs in *Kingdom Come: Deliverance 2* is part of the game's charm. Some are friendly, others hostile, and their intentions aren't always immediately clear. This guide focuses on the Wandering Drunk and what to do with him.
Kingdom Come Deliverance 2 Wandering Drunk Location

The Wandering Drunk resides in an abandoned barn slightly north of Semine, a short detour from the main roads. While riding north, you'll encounter a herdsman who warns you about a hostile vagrant nearby.
Inside the barn, you'll find a beggar NPC outside. 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 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 with no associated quests. It's likely he simply lost his home and family; the keys are probably from his former residence, purely for narrative flavor.
Many NPCs carry keys with unknown purposes. This is likely the case for the Wandering Drunk's keys as well.
