The King Cat Quest in Roblox Abyss is one of the most hidden endgame missions in the game. Many players never discover it because the NPC is located inside a secret passage deep within a late-game biome. However, completing this quest rewards one of the strongest artifacts available, making it extremely valuable for long-term progression.
This guide explains exactly where to find King Cat, what you need before starting, and how to complete the quest efficiently.
Where to Find King Cat in Abyss
King Cat is located inside a hidden area within the Spirit Roots Cave, which is an endgame zone. Because of the depth and difficulty of enemies in this region, you should only attempt to reach this NPC after properly gearing up.
To reach King Cat, start by traveling to the Spirit Roots biome. From the safety area, take the tunnel on the left side and swim deeper into the cave system. When the path splits, continue left again and keep moving forward until you pass through the Golem Cave.
Eventually, you will enter a larger open chamber. Inside this area, look carefully along the right wall. You will find a small crack with a visible treasure chest inside.
To access the hidden passage, move into the upper-left corner of the wall behind that chest. This triggers a hidden entrance that pushes you into a secret tunnel leading directly to the King Cat NPC.
Required Gear Before Attempting the Quest
Since Spirit Roots is a deep and dangerous area, proper equipment is essential.
You should have at least an Oxygen Tube to survive the depth for extended periods. A Magroot Gun or equivalent high-tier tool is also recommended to handle tougher fish and defend yourself while farming.
Attempting this quest without strong gear will make farming extremely difficult and time-consuming.
King Cat Quest Requirements
Once you find and interact with King Cat, you will receive a long multi-objective quest that requires collecting various rare fish and resources.
You must catch three Angelic Mutated Fish, twenty Golden Mutated Fish, three Blue Fin Tuna, five Big Mouth Fish, twenty Black Fin Tuna, and twenty Jellyfish.
In addition to fishing tasks, you must also crack twenty Geodes and bring one hundred thousand cash to complete the quest.
Because most of these fish are found around Spirit Roots, you will spend most of your time farming in that biome.
How to Farm Quest Items Efficiently
The best strategy is to focus on Spirit Roots fishing spots where multiple required fish spawn. Farming mutated fish should be prioritized first since they are rarer and take longer to obtain.
While fishing, collect Geodes whenever possible so you can complete the geode requirement naturally instead of farming them separately later.
Saving money before starting the quest is also recommended so you do not need to grind currency at the end.
King Cat Quest Reward — King’s Fortune Artifact
Completing the quest rewards you with an artifact called King’s Fortune, which is considered one of the strongest endgame items in Abyss.
This artifact significantly increases cash gain, boosts movement speed, and reduces ability cooldown times. Depending on its roll, it can provide up to a twenty-one percent increase in cash gain, noticeable cooldown reduction, and faster mobility.
Because it has no negative effects, it is extremely valuable for both farming efficiency and late-game progression.
Why the King Cat Quest Is Worth Completing
Although the quest is lengthy and resource-heavy, the King’s Fortune artifact provides permanent benefits that drastically improve your long-term gameplay.
Players focused on maximizing income, reducing cooldowns, and improving mobility will find this reward especially impactful.
The King Cat Quest in Abyss is one of the most rewarding hidden missions in the game. While reaching the NPC requires careful exploration and completing the objectives demands significant effort, the powerful artifact reward makes the entire process worthwhile.
With proper preparation, efficient farming strategies, and patience, you can complete the quest and gain a major advantage in late-game progression.
