Starting the Eternal Corridor quest at Marni’s mansion
To begin your journey, you need to head to Marni’s Mansion in Delesyia, where the entire questline kicks off. Inside, you’ll find the Old Research Journal, which acts as your entry point into the Eternal Corridor.

Once activated, you are transported into a structured sequence of puzzle zones, each acting as a gate that tests different mechanics. This isn’t a simple combat quest—you’ll need awareness, patience, and adaptability.
The Eternal Corridor is divided into multiple distinct areas, and you must complete each one in sequence to unlock the final encounter.
Gate of Advancement
This serves as your introduction. Expect basic traversal and interaction puzzles that teach you the rules of the corridor.

Skypillar Archipelago
Here, verticality becomes important, requiring you to carefully move between floating structures while managing timing and positioning.

Steamclouds Station
This area introduces movement disruptions and environmental hazards, forcing you to adapt quickly and avoid being pushed off course.

Steelsail Archipelago
You’ll encounter more complex navigation challenges, combining timing, movement, and awareness of shifting platforms.

Fleet of Archives
This is the final puzzle stage before the boss. It blends previous mechanics into a more demanding sequence, ensuring you’re fully prepared with Nature’s Retribution skill.

Facing Clockwork White Horn at the Clockwork Heart
After completing all puzzle zones, you reach the Clockwork Heart, where the boss—Clockwork White Horn—awaits.
This fight is not about brute force. It’s a positioning-heavy encounter where understanding attack patterns is critical.
How to defeat Clockwork White Horn
Step 1
Stay close to the boss at all times. Position yourself underneath its body to avoid many of its sweeping and ranged attacks.

Step 2
Watch for the invulnerability phase. When the boss becomes briefly invulnerable, it signals the incoming ram attack, which is its most dangerous move.

Step 3
Dodge the ram attack immediately. This move can deal massive damage, so prioritizing avoidance is more important than dealing damage in that moment.

Step 4
Build stagger using force palm. Focus on increasing the stagger bar steadily. Once the boss is staggered, you’ll get a window to land uninterrupted attacks.

Step 5
Avoid the horn rend attack. This attack becomes especially threatening later in the fight, often catching players off guard when they get greedy with damage.

Step 6
Capitalize on stagger windows. When the boss is down, unleash your strongest attacks to shorten the fight significantly.
White Horn Ring stats and effects breakdown
The White Horn Ring is designed for players who favor sustained combat rather than burst-heavy builds.
| Effect Type | Impact |
|---|---|
| Attack Boost | Minor increase to base damage |
| Attack Speed Penalty | Slightly slower attacks |
| Stamina Regen | +2% regeneration |
| Combat Style Fit | Aggressive, stamina-heavy play |
The stamina regeneration is the standout feature, especially if you rely on dodging, chaining attacks, or maintaining pressure during boss fights. While the attack speed penalty may feel noticeable, the trade-off becomes manageable if you adapt your timing.

When you should use the White Horn Ring

You’ll get the most value from this ring if your playstyle involves constant movement and sustained offense. It works particularly well in longer fights where stamina management becomes critical.
If you rely heavily on quick attack speed builds, this ring may feel slightly restrictive, but for balanced or stamina-focused setups, it provides a reliable boost.
