Where to find the basement key in Blue Prince

The basement key can only be found in the antechamber. Unlike the other keys you’ll need to unlock doors around the map, the basement key can only ever be found in this room, and you won’t have to solve any puzzles to get it. With that said, getting into the antechamber is a puzzle in itself. You need to unlock the doors leading into the antechamber using levers in three other rooms: the Grand Hall, the Secret Garden, or the Greenhouse.
