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 slightly north of Semine, off the main roads. While riding north, you'll meet a herdsman who warns you about a hostile vagrant nearby.
Entering the barn's vicinity reveals a beggar NPC outside. He'll become aggressive if approached. Currently, meaningful interaction beyond combat (killing or incapacitating him) appears impossible. After defeating him, you can loot his body for 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 provides no clues about the Wandering Drunk's identity. He might be a nod to a similar beggar NPC from the first game, a character who lost everything and became a vagrant with no associated questlines. It's plausible his story involves the loss of home and family, and the keys are simply narrative flavor, belonging to his former residence.
Many NPCs in the game carry keys with no apparent use, suggesting the Wandering Drunk's keys fall into this category.
