What to know
- The Ruined Lantern is a secret artifact in Abyss that boosts oxygen, movement speed, and carry weight.

In Abyss, progression becomes increasingly demanding as you dive deeper into hostile underwater zones. If you’re struggling with oxygen limits, slow mobility, or tight inventory space, the Ruined Lantern is one of the most impactful mid-to-late game upgrades you can unlock. This artifact isn’t purchased from a shop or found randomly—it requires completing a specific quest chain tied to a hidden NPC.
What is the Ruined Lantern in Abyss
The Ruined Lantern is considered a power spike item because it directly improves survivability and farming efficiency, making resource grinding and deeper biome exploration far easier.
Angler Cave is a dangerous underwater zone designed for higher-level players. You should not attempt this area underleveled or with early-game diving gear. The oxygen drain is significant, and the surrounding waters are populated with aggressive fish, including Angler variants and other hostile species.

| How to Obtain | Complete quests for the Lightkeeper NPC |
| Location of Lightkeeper | Inside Angler’s Cave |
| Quest Goal | Finish Lightkeeper’s quest chain to unlock Ruined Lantern reward |
| Access Needed | Must have access to Angler’s Cave (finish Lost Captain questline first) |
Once inside Angler Cave, you’ll need to navigate deeper into the cavern system to locate the Lightkeeper NPC, who stands apart from the hostile wildlife. He serves as the quest initiator for the Ruined Lantern.
How to unlock the Ruined Lantern step by step
Step 1
Reach at least Level 35 and equip strong oxygen gear. Without sufficient oxygen reserves, exploring Angler Cave becomes extremely risky. Equip improved tanks or gear that extends underwater duration and boosts survivability.
Step 2
Enter Angler Cave and proceed carefully through enemy-filled corridors. Expect aggressive fish attacks. Clear threats methodically rather than rushing, as being swarmed can quickly deplete health and oxygen.
Step 3
Locate the Lightkeeper NPC within the cave. Interact with him to receive the Ruined Lantern quest. He will outline the items required to restore or recover the artifact.
Step 4
Hunt and collect all required materials. This includes defeating the King Anglerfish, which drops rare components, and farming several additional fish species throughout the region.
Step 5
Return to the Lightkeeper with all quest items in your inventory. Upon successful turn-in, you will receive the Ruined Lantern artifact as your reward.

The King Anglerfish is the most difficult part of the quest. It has higher durability and damage output compared to normal enemies. Efficient dodging, sustained DPS, and oxygen management are crucial during this fight.
How to defeat the King Anglerfish efficiently
Preparation is key. Enter the encounter with full oxygen and health. Keep distance when possible, circle-strafe to avoid direct attacks, and avoid being pinned against cave walls. If your oxygen runs low during the fight, disengage and recover before re-engaging.
High-damage weapons dramatically shorten the encounter. If possible, bring gear that enhances underwater combat mobility. Once defeated, loot the Head and Meat drops, which are mandatory for quest completion.
What makes the Ruined Lantern so valuable
The Ruined Lantern is not cosmetic. It provides meaningful gameplay advantages that stack with your current equipment.
| Stat Boost | Effect on Gameplay |
|---|---|
| Oxygen Capacity | Extends dive duration significantly |
| Movement Speed | Faster underwater traversal |
| Carry Weight | More loot per run |
With extended oxygen, you can explore deeper zones without constantly resurfacing. Increased speed reduces travel time between farming routes. Expanded carry capacity means fewer return trips to base, improving grinding efficiency.
For players actively farming materials or preparing for deeper progression areas, this artifact becomes a core build component.
Efficient farming strategy for the required fish
Focus your hunting routes within Angler Cave and surrounding deep-water biomes to minimize travel time. Prioritize aggressive fish first to reduce danger while farming passive species. Use safe pockets inside the cave as temporary recovery points to manage oxygen and health.
Golden Fish and Shadow Fish may require patience due to spawn variability. Staying in darker sections of the cave increases Shadow Fish encounter chances. Keeping oxygen boosts active ensures longer farming sessions.
Rewards from the Lightkeeper quest
| Reward | Type | Impact |
|---|---|---|
| Ruined Lantern | Artifact | Major survivability and farming boost |
Unlike currency-based rewards, this artifact directly increases long-term efficiency. It remains useful well beyond the level requirement and is considered a mid-game milestone item in Abyss progression.
Why this artifact changes your progression pace
Before unlocking the Ruined Lantern, exploration is often limited by oxygen constraints and inventory space. After acquiring it, you can chain longer expeditions, farm rare materials faster, and safely engage tougher enemies without frequent retreats.
If you plan to grind deeper regions or prepare for future content updates, securing this artifact early at level 35+ gives you a significant advantage.
