The Drowner's Map is one of the first you'll find in Kingdom Come: Deliverance 2, introducing you to the whole map mechanic for finding hidden treasures. This one isn't too difficult to solve, though as with other maps, it's poorly drawn to say the least—I guess Medieval mapmaking wasn't the most exact science.
You'll pick up the Drowner's Map from an unfortunate submerged treasure hunter who was looking to claim the fabled water goblin's plunder for himself. Luckily for you, he wasn't successful and so you can liberate the map from his somewhat soggy corpse. For those who are stumped or want to know where the treasure is, I'll explain its exact location on the map and how to reach it.
