The Lost Captain Quest Chain is a series of four challenging quests in Roblox Abyss that players can access once they reach Level 35. This questline is essential for end-game progression, as completing it unlocks the Captain’s Last Wish badge and grants access to Angler Cave, where you’ll find the Lightkeeper NPC who sells some of the best late-game weapons and equipment.
The quest chain involves catching rare fish, finding treasure chests, and cracking geodes across different biomes. Each quest progressively increases in difficulty and requires better equipment to complete efficiently.
Prerequisites and Preparation
Level and Equipment Requirements
Before starting the Lost Captain quest chain, you’ll need:
- Minimum Level 35 – This is non-negotiable
- $10,000 cash for the first quest initiation
- Recommended Equipment: Lost Spirit Tube and Lost Spirit Gun (or equivalent)
- Oxygen Management: At least Advanced Oxygen Pods for extended diving
Best Equipment for Each Quest
Based on my extensive testing, here’s the optimal equipment setup:
| Quest | Best Tube | Best Gun | Alternative |
|---|---|---|---|
| Quest 1 | Lost Spirit Tube | Lost Spirit Gun | Oxy Tube + Magroot Gun |
| Quest 2 | Lost Spirit Tube | Lost Spirit Gun | Oxy Tube + Magroot Gun |
| Quest 3 | Lost Spirit Tube | Lost Spirit Gun | Lost Spirit Tube + any gun |
| Quest 4 | Lost Spirit Tube | Lost Spirit Gun | Required (no alternatives) |
Preparation Tips
- Farm EXP in Forgotten Deep before starting – fish here are faster to catch
- Stock up on Oxygen Pods – you’ll be spending lots of time underwater
- Bring Speed Potions for the final quest – Bluefin Tuna are incredibly fast
- Join the official Discord for private servers and trading opportunities
Quest 1: The Beginning
Starting the Quest
To begin the Lost Captain quest chain, you need to:
- Reach Level 35 – Focus on farming Forgotten Deep fish for fast EXP
- Gather $10,000 – Complete Kraken’s quests or sell valuable fish
- Find the Lost Captain – Located far east of Forgotten Deep (requires Zepline or Oxy Tube to reach safely)
Quest 1 Objectives
| Objective | Quantity | Location | Difficulty |
|---|---|---|---|
| Ancient Shark | 1 | Ancient Sands | Medium |
| Bigmouth Fish | 3 | Ancient Sands | Easy |

| Treasure Chests | 55 | All biomes | Easy-Medium |
Quest 1 Strategy
Pro Tip: Start with the easiest objectives first. Farm Cavefish in Forgotten Deep, then move to Ancient Sands for the other fish. Save treasure chest hunting for last – you’ll naturally find them while completing other objectives.
Efficient Route:
- Farm 6 Cavefish in Forgotten Deep
- Head to Ancient Sands for remaining fish
- Hunt treasure chests while traveling between fishing spots
- Use Lost Spirit Tube for maximum oxygen efficiency

Optimal Farming Route:
- Start with Eyefish, Hammer Shark, and Sailfish in Ancient Sands
- Hunt for Negative and Neon Mutated Fish while fishing
- Crack geodes as you find them (Virelia NPC)
- When you have most fish, head to Spirit Roots for Whale Meat
- Server hop if Whales aren’t spawning
