Beyond the four major Cartels of Undermine in patch 11.1, a lesser-known faction operates in the shadows: Darkfuse Solutions. Once working under Gallywix, this cartel has rebranded itself and returned to the market with a new name, new strategies, and a whole lot of ambition. While they may have made a few enemies in the past, goblins never back down from a business opportunity.
Darkfuse Solutions is a reputation-based faction that players can unlock after completing the Liberation of Undermine raid and progressing through a short questline. This guide will walk you through how to unlock the reputation, the best ways to farm Market Research (the currency needed to gain rep), and the rewards you can earn for your efforts.
How to unlock Darkfuse Solutions

To gain access to Darkfuse Solutions, follow these steps:
- Complete the Liberation of Undermine Raid – Successfully clear this raid on any difficulty (including Story mode). You only need to defeat Chrome King Gallywix to progress.
- Finish the Story Quest: Liberation of Undermine: The House Loses – This essential quest marks your entry into the post-raid story content.
- Pick Up the Overly-Sealed Letter – After completing the quest, head to the Incontinental Hotel in Undermine. On a lobby table at [43.2, 51.6], you’ll find a mysterious, overly-sealed letter.
- Start the Quest: Diversified Investments – Interact with the letter to begin this quest, which introduces you to Sitch Lowdown, the Darkfuse Quartermaster.
- Enter the Darkfuse Quarters – The hidden quarters are located behind a sewer entrance at [29.7, 41.1]. Inside, you can interact with Sitch Lowdown and complete Diversified Investments, officially unlocking the reputation.
- Begin Earning Reputation – Once the reputation is unlocked, you can start farming Market Research to increase your standing with Darkfuse Solutions.
As you can see, the hardest part of unlocking Darkfuse Solutions is finishing the Undermine storyline and defeating Chrome King Gallywix in the Liberation of Undermine raid. After that finishing Darkfuse Solution quests is easy!
How to farm Market Research

Market Research is a special currency in Undermine, used exclusively to gain reputation with Darkfuse Solutions. It is obtained through various activities in Undermine and can be turned in to Sitch Lowdown for Box of Darkfuse Miscellany, which grants 500 reputation per turn-in.
Market Research sources:
- Normal Mobs & Shiny Piles of Trash: Small chance to drop 1 Market Research.
- Undermine Normal Rares: Guaranteed 1-2 Market Research.
- Undermine Cartel Rares: Guaranteed 3-4 Market Research.
- Undermine Elite Rares: Guaranteed 5-6 Market Research.
- Rare Darkfuse Precipitant: Guaranteed 12-14 Market Research.
- SCRAP Dig Chest Rewards: Guaranteed 14-16 Market Research.
Best farming strategies:
- SCRAP Pile Digging – The safest and most efficient way to earn Market Research, as it provides steady income with minimal risk.
- Rare Mob Farming – A good alternative if you have a strong group, as cartel rares and elite rares provide larger amounts of Market Research. Rares spawn all around the Undermine and are marked on your map, making it simple to navigate and defeat them.
- Acquiring Weakened Items – Some items acquired through Darkfuse Solutions may debuff your character but increase Market Research drop rates, making them a useful tool for dedicated farmers.
Reputation requirements:
Neutral to Exalted requires 8,400 Market Research, meaning you will need 84 total turn-ins.
Note
Market Research is not warbound and cannot be transferred between characters.

Conclusion
Fun fact: Darkfuse Solutions was previously known as Blackfuse, a direct homage to the Siege of Orgrimmar war machines used by Garrosh Hellscream. The original Siegecrafter Blackfuse, a genius goblin engineer, was the mastermind behind these devastating weapons and the original leader of the cartel. Following the fall of Siegecrafter Blackfuse and the events of Orgrimmar’s siege, the cartel rebranded itself as Darkfuse Solutions, seeking to distance itself from past failures while keeping the legacy of goblin ingenuity alive.
Darkfuse Solutions may not have the notoriety of the other cartels, but they offer valuable rewards and an engaging reputation grind. Whether you prefer farming SCRAP piles or hunting down rare mobs, there are multiple ways to reach Exalted status and claim exclusive rewards.
