Item from Stardew Valley by ConcernedApe (Eric Barone)
Found at floor 120 of the mines — the key that opens Skull Cavern and the game's hardest challenges.
The Skull Key is the reward for reaching the bottom of the mines — floor 120. It unlocks Skull Cavern in the Calico Desert, transitioning the player from structured mining (elevator checkpoints, finite floors) to infinite, dangerous descent. Getting the key is itself a significant achievement — the lower mine floors are genuinely challenging. Using it opens the game's most intense combat and mining content.
A dark, skull-shaped key made of some unidentifiable metal. It's cold to the touch and faintly unsettling. The skull design matches the Skull Cavern entrance perfectly.
