Darkfuse Solutions is Undermine's second renown track, run separately from the Cartels of Undermine, and it has no single repeatable mob to farm — renown comes from Undermine weekly quests, world quests, rare elites and zone events. The fastest route is clearing every weekly reset in full. Renown is account-wide in The War Within, so alts feed the same bar.

  • Where: Undermine, on Kezan — the goblin city zone added in The War Within's Undermine(d) content patch.
  • Two separate tracks: Cartels of Undermine (the main zone renown, with your chosen cartel allegiance) and Darkfuse Solutions. Progress on one does not fill the other.
  • Main renown sources: the zone's weekly quest content, Undermine world quests, rare elites, and the zone's recurring events.
  • Zone currency: Kej, which you bank alongside renown for vendor purchases.
  • Account-wide: renown earned on any character adds to the same track, so a geared alt is a legitimate farming tool, not wasted effort.
  • Pacing: a meaningful share of the track sits behind weekly-reset content, which is why Darkfuse is a multi-week project rather than a one-evening grind.
  • Not purchasable: renown cannot be bought with gold, traded, or mailed between characters.

The practical weekly loop looks like this: open the map, sweep every Undermine world quest that is up, clear the zone's weekly objectives, and kill rares on the way between them rather than making a dedicated rare lap. Doing the weekly content first matters — the big chunks are gated, so missing a reset costs you more than a slow day of world quests ever will.

Is Darkfuse Solutions renown account-wide?

Yes. The War Within made renown tracks account-wide, so anything you earn on an alt lands on the same Darkfuse bar. That changes the optimal play: log whichever character clears Undermine content fastest, not the one that started the zone.

Rewards you unlock stay unlocked across the account too, which is why people push one track hard instead of splitting effort across several characters.

How long does it take to max Darkfuse Solutions?

Because the track leans on weekly content, expect it to run over several weeks of consistent play rather than a single marathon session. Someone clearing every weekly and mopping up world quests progresses noticeably faster than someone logging in once a week.

If you have skipped resets, catch-up is realistic — you just cannot compress the gated portion into one day. Check your in-game renown tab for the exact remaining levels before planning, since the numbers shift with content updates.

What do you actually get from Darkfuse renown?

Renown levels on the track hand out cosmetic and collection rewards, vendor access, and account-wide unlocks tied to the Undermine storyline. If you are farming purely for power, other content pays better per hour — Darkfuse is a collection and completion track first.

Check the renown pane in game before committing: it lists each level's payout, so you can decide whether you want the whole track or just the levels up to the reward you actually care about.

Do dungeons or raids give Darkfuse reputation?

Darkfuse renown is a zone-content track — your progress comes from Undermine itself, not from unrelated instanced content. Time spent in Undermine on quests, world quests and rares is what moves the bar.
