Unlocking the Secrets of Elden Ring: What Does the Slime Key Open?
For many adventurers navigating the treacherous landscapes of Elden Ring, the discovery of a seemingly innocuous item can spark a burning question: "What does the Slime Key open?" This particular key, often found in the early to mid-game, is a gateway to some significant rewards and crucial progression within the Lands Between. Let's delve into the specifics of this important item.
The Primary Target: The Royal Remains Set
The most prominent and sought-after reward unlocked by the Slime Key is the Royal Remains Set. This is a full armor set that offers respectable physical and stance defenses, making it a viable option for many builds, especially in the earlier stages of the game. It's particularly known for its distinct, somewhat unsettling aesthetic, fitting right into the grim world of Elden Ring.
Where to Find the Slime Key
Before you can open anything with it, you need to acquire the Slime Key itself. It's typically found in the Crypt of Sellia, located in the Caelid region of Elden Ring. This area is known for its challenging enemies and hidden passages. Players will need to navigate through the crypt, often dealing with spectral enemies and traps, to reach the location where the Slime Key is stashed.
The Door It Opens: The Chamber of Miquella's Haligtree
The Slime Key's primary purpose is to unlock a specific door within the Cave of the Forlorn. This cave is situated in the Consecrated Snowfield, a late-game area that requires players to obtain two halves of the Haligtree Secret Medallion to access. Once inside the Cave of the Forlorn, you'll encounter a locked door. Using the Slime Key on this door will grant you access to a treasure chamber.
Within this chamber, you will find:
- The aforementioned Royal Remains Set (Helmet, Armor, Gauntlets, Greaves).
- A significant amount of Runes, which are the in-game currency used for leveling up and purchasing items.
Why the Slime Key is Important
The Slime Key is significant for several reasons:
- Early Access to Good Gear: While the Consecrated Snowfield is a late-game area, obtaining the Haligtree Secret Medallion can be done at various points. If you manage to access the area earlier, the Royal Remains set can provide a substantial defensive boost that can help you tackle later challenges.
- Completing Sets: For players who enjoy collecting all the armor sets in the game, the Slime Key is essential for obtaining the complete Royal Remains set.
- Resource Acquisition: The runes found within the treasure chamber are always a welcome bonus, especially when you're looking to invest in new weapons, spells, or stat upgrades.
A Note on Progression and the Slime Key
It's important to note that while the Slime Key unlocks a valuable treasure, it is not necessarily a mandatory item for completing the main story of Elden Ring. However, for players who wish to maximize their gear and build options, or those aiming for 100% completion, the Slime Key and the rewards it provides are highly recommended.
Frequently Asked Questions about the Slime Key
How do I get to the Cave of the Forlorn?
Accessing the Cave of the Forlorn requires you to obtain the two halves of the Haligtree Secret Medallion. Once assembled, you can activate a secret teleporter at the Grand Lift of Rold to reach the Consecrated Snowfield, where the cave is located.
What if I can't find the Slime Key in the Crypt of Sellia?
Ensure you have fully explored the Crypt of Sellia. The Slime Key is generally found in a specific chest or on a corpse within the crypt. Double-check walkthroughs or detailed maps if you're having trouble pinpointing its exact location.
Is the Royal Remains Set good for the entire game?
The Royal Remains Set offers good early to mid-game defenses. While it can still be viable later on with upgrades and careful build management, you will likely find stronger armor sets with higher defense and specialized resistances as you progress through the later stages of Elden Ring.
Can I use the Slime Key on other doors?
No, the Slime Key is specifically designed to open the single locked door within the Cave of the Forlorn leading to the treasure chamber containing the Royal Remains Set. It is not a universal key for all locked doors in Elden Ring.
