Shelleton Key

Shelleton Key is a passive item.

Effects

 * Allows any chest or locked door to be opened without using a key.
 * Increases curse by 1 while held.

Trivia

 * If the player has Heart Locket, it grants an extra heart container.
 * This item's name is a portmanteau of Shelleton, a demon found in the Gungeon, and Skeleton Key, a type of master key reduced to its essential parts.
 * It is also a reference to an item Skeleton Key from The Elder Scrolls series from Bethesda Software, which serves as an unbreakable lockpick. Its unlock condition is derived from the fact that the item is usually associated with the Thieves Guild and Nocturnal, a Daedric Prince who also has some association with the Thieves Guild.
 * This item's tagline is a reference to the fact that locks in the Gungeon are sentient, and thus they literally die to the player when the Shelleton Key is used.
