If you're playing Path of Exile 3.26 and want a solid way to farm clusters, running a Delirium-focused Atlas tree is one of the most reliable options. The trick is to load up on passives that extend Delirium fog, increase mirror spawns, and boost reward tiers. Once that's set, you just stack monster density with scarabs and map modifiers, so the fog sticks around long enough to maximize kills and push the reward bar to higher levels PoE 1 Currency.

The choice of maps makes a big difference here. Fast and simple layouts like Strand or Dunes are ideal because they keep you moving and prevent wasted time. The whole point is to chain maps quickly, ideally clearing each in two or three minutes. It's not a strategy that demands crazy investment either—you can get it going with six to ten divines for scarabs, Delirium orbs, and a pool of tier 16 maps, especially if you don't mind crafting some of your gear yourself.

For builds, anything fast, tanky, and consistent works best. Popular choices include Righteous Fire, Tornado Shot, Lightning Arrow, or Poisonous Concoction. If your character can pump out around five to ten million DPS while keeping about sixty to a hundred thousand effective HP, you'll be fine. Having good mobility is just as important, since you'll often be outrunning the fog and need to reposition constantly during tougher encounters.

The clusters are the main prize, and they sell well because of their demand for crafting and trading. On top of that, you'll see a steady flow of Simulacrum splinters, Delirium orbs, and other currency items that keep your income varied. The key is to sell or combine clusters regularly so you keep profits rolling instead of letting your stash clog up. The more consistent you are with your map runs, the more reliable your returns will be.

It's also smart to know when to cut things short. Once you stack too many Delirium layers—usually five or six—the monsters can become a slog and eat up too much time. It's often better to finish up early and jump into the next map rather than risk slowing your overall pace. Efficiency is what makes this strategy shine, not dragging out a single map for diminishing returns.

This farming loop works because it balances reward and accessibility. You don't need mirror-tier gear, and you don't have to sink insane currency to get started. With the right Atlas tree setup, some well-chosen scarabs, and maps that you can clear quickly, you'll end up farming clusters at a steady clip while also scooping up plenty of side loot buy PoE Currency. It's fast, consistent, and fun, which is exactly what most players are looking for in a league strategy.
