In The Elder Scrolls IV: Oblivion, the Skeleton Key is a prized Daedric artifact that significantly enhances your lockpicking abilities. This unbreakable lockpick not only makes unlocking doors and chests easier but also boosts your Security skill by 40 points as long as it’s in your inventory. To obtain this powerful tool, you’ll need to complete the “Nocturnal” quest, which becomes available once your character reaches level 10.

Once you’ve achieved level 10, head to the Nocturnal Shrine located northeast of Leyawiin. The shrine is marked by a large statue of the Daedric Prince Nocturnal. Upon arrival, speak with Mor gra-Gamorn to initiate the quest. Nocturnal will task you with recovering the stolen Eye of Nocturnal, a sacred artifact that has been taken by thieves in Leyawiin.
Investigating in Leyawiin
Travel to Leyawiin and make your way to Weebam-Na’s house, situated in the center of town. Inside, you’ll find two Argonians: Weebam-Na and Bejeen. When questioned about the Eye of Nocturnal, both will deny any knowledge of the artifact. To uncover the truth, you’ll need to eavesdrop on their conversation.
To do this, enter stealth mode by crouching and position yourself out of sight within the house. If your Sneak skill is low, consider using an invisibility spell or potion to remain undetected. Wait patiently until the two Argonians discuss the Eye’s whereabouts. They’ll reveal that the artifact is hidden in Tidewater Cave, located southeast of Leyawiin near the coast of Topal Bay.
Retrieving the Eye of Nocturnal
Make your way to Tidewater Cave, which is inhabited by various creatures such as trolls and wolves. Ensure you’re well-prepared with appropriate gear and healing items. Once inside the cave, follow these directions to locate the Eye:
- Take the first left turn.
- Continue straight and take another left at the next intersection.
- Proceed until you reach a flooded section of the cave.
- Dive into the water and swim through the submerged tunnel.
- Look for a glowing orb next to a chest; this is the Eye of Nocturnal.
After securing the artifact, exit the cave and return to the Nocturnal Shrine.
Claiming the Skeleton Key
Present the Eye of Nocturnal to the shrine to complete the quest. As a reward, Nocturnal will grant you the Skeleton Key. This unique item functions as an unbreakable lockpick and provides a constant 40-point boost to your Security skill while in your possession. With the Skeleton Key, lockpicking becomes significantly easier, allowing you to access locked areas and containers with minimal effort.
Tips for Using the Skeleton Key
- Unbreakable Lockpick: The Skeleton Key never breaks, eliminating the need to carry multiple lockpicks.
- Security Skill Boost: The 40-point increase to your Security skill enhances your ability to pick locks and can help you access areas that were previously too challenging.
- Auto-Attempt Feature: With the Skeleton Key, you can use the “Auto Attempt” option repeatedly until the lock opens, bypassing the lockpicking minigame.
- Caution When Arrested: If you’re arrested, the Skeleton Key will be confiscated along with other stolen items. To avoid this, consider storing the key in a safe location before engaging in activities that might lead to arrest.
By following these steps, you’ll acquire one of the most valuable tools in Oblivion, making your adventures in Tamriel more accessible and enjoyable.
