The Skeleton Key is a rare key obtained from the Treasure Hunter after completing the quest "Open Sesame".
The key can opens bronze and silver pirate chests, and have a 20% chance of breaking per use. If you have a corresponding key in your inventory when opening a chest (say bronze chest = bronze chest key), then the Skeleton Key will not be used. It should also be noted that this key will not open lockboxes, even if they are the corresponding color.
- Unlike some other desert island quests, the "Open Sesame" quest can be completed multiple times and more than one Skeleton Key can be acquired.
- The Skeleton Key was crafted by a highly skilled blacksmith named Ealgar. The key is supposed to be of ancient origin as explained in Ealgar's Journal.
