How to Unlock Darkfuse Solutions Reputation

To unlock the Darkfuse Reputation in the Undermine first you will need to have completed the undermine campaign. Once you’ve completed the campaign, you can dive right into the Darkfuse Solutions Reputation Grind.

Complete the Undermine Campaign

Firstly, you need to complete the campaign within the undermine to access the Darkfuse Reputation. This step is crucial to unlocking the post-campaign quests that are linked to the Darkfuse Solutions Rep.

Each quest builds upon the last one, so if you get lost simply open your quest log (L) and look for the top quest listed under “Undermine Campaign”, markers should guide your path and give you an idea of exactly where to go next.

Clear the Liberation of Undermine Raid Instance

Once the campaign has been completed, you will get a quest called “Liberation of Undermine: The House Loses”. To complete this you will need to slay the Chrome King Gallywix on any difficulty (including Story / Solo Mode). Chrome King Gallywix does have tricky mechanics regardless of difficulty, so be sure to research mechanics beforehand. For guides on this raid instance, check out Method’s Liberation of Undermine Raid Guides.

Unlocking the Darkfuse Solutions Reputation

Once you’ve completed the raid and handed the quest in, you will find an Overly-Sealed Letter sitting on the front desk of the Intercontinental Hotel (Central Undermine), interacting with this letter gives the rather shady and vague quest “Diversified Investments”. This quest will have you seek out a potential business opportunity.

This invitation in short brings you to a sewer grate in Hovel Hill, click on the sewer grate and jump into the hole.

Darkfuse Solutions Entrance to Sitch Lowdown

Down in the sewers you will meet Sitch Lowdown, a goblin who explains to you who the Darkfuse are looking for since Gallywix died.

You will only need to do it once on any of your characters. If you don’t get the “Diversified investments” quest beforehand, via the letter, then you wont get any response from Sitch Lowdown.

Once you’ve handed this quest in, you will have Sitch Lowdown as a vendor and this is the first step in being able to farm Darkfuse Solutions reputation.

Now we have unlocked the reputation, it’s time to farm Darkfuse Solutions reputation fast.

Farming Darkfuse Reputation

Fundamentally from here the reputation can be gained mainly from either doing the scrap quests and world quests, slaying rare elites throughout the undermine and farming “market research”.

To get Reputation with Darkfuse Solutions you will need to collect 100 Market Research and use that to buy a Box of Darkfuse Miscellany from Sitch Lowdown. This will reward you with 500 reputation for Darkfuse Solutions. You will need to complete 84 hand-ins to achieve Exalted status with Darkfuse Solutions.

Do also keep in mind that Market Research is a transferable currency between your warband, so check those alts!

Scrap Pile Farming

Join scrap farm groups or run solo around undermine completing “Scrap Piles” (digging through scrap pile) and defeating any mobs that spawn. Once this is done, you’ll get a treasure chest with some market research in, this is the most soloable way to farm this reputation. You will see many other players completing these scrap piles, simply join them and wait for the next one to spawn: Rinse and Repeat.

How to get Market Research in the Undermine

To get Market Research you would have first unlocked the darkfuse solution reputation and then it's as simple as slaying mobs throughout the undermine, which have the possibility to drop between 1 and 6 market research each. Do bare in mind that the rare elites have a better drop rate and can drop even more Market Research.

Fastest Way to Farm Darkfuse Solutions Reputation

The fastest way to farm reputation for Darkfuse Solutions is to join a custom LFG Darkfuse 2x4 group. Then simply head over to the top right hand side of Undermine and help slay masses of mobs. This will get you the highest drop rate of Market Research possible. This is a rather lengthy grind but it’s worth doing nevertheless.

Custom LFG Darkfuse Farm Feature

Below you can see how the farming spot is setup to be both effective and efficient. Players split into 2 groups of 4 players (referred to as 2x4) which is the maximum you can have and still benefit from mob tagging to increase loot and turn the area into a hyperspawn (Mobs that spawn faster when slain faster).

Both groups stay in the centre and one group runs towards the left side pulling all mobs to the centre and the other group runs to the right side pulling all mobs to the centre.

By forming a custom LFG with two teams of 4 players you will have the easiest and smoothest experience to get this grind done as fast as possible. If you are choosing to make a group, aim to invite ranged classes as they will pull the most amount of mobs as possible, which in turn will speed up your reputation grind.

How to Farm Market Research EVEN FASTER (Goblin Mode)

Sitch Lowdown sells 2 very interesting products.

Purchase Prototype Auto Advertisers from Sitch Lowdown which cost 100 resonant crystals, this unfortunately buffs enemies, but increases their market research drops significantly, meaning you have to spend far less time grinding this reputation: Win Win Right?

On top of this, you can also use Experimental Goblin Fuel Supplement which reduces your total HP by 50 % and provides a random combat buff to you. This in turn also makes enemies drop additional Market research which makes your grind that much faster. Try to make sure you’re inviting higher item level players so you slay mobs faster!
