Path of Exile’s 3.26 League offers some of the most lucrative farming strategies in recent memory—if you know how to optimize them. This PoE 3.26 mirror farming guide breaks down 3 best atlas trees to farm mirrors.
Each Path of Exile 3.26 mirror farming strategy is tested, optimized, and profitable, whether you're playing solo or in a group. First, we’ll look at the Legion + Dunes farming setup, built around maximizing Legion encounters using scarabs and Atlas passives. Then, we’ll follow the progression of a Cobra Lash Deadeye—a non-meta build that still farmed a mirror in just four days using smart upgrades, strategic mapping, and precise timing. Finally, we’ll break down a Harbinger/Beyond hybrid strategy, built for juiced Basilica and Jungle Valley maps that rain poe currency shards and Divination cards.
1. Map Setup: Legion in Dunes
Map: Dunes (Mesa-scryed for div card targets)
Great open layout and fast clear
Good synergy with Legion encounters
2. Scarab Setup
You’ll need 4 scarabs per map:
Legion Scarab of Eternal Conflict – Lets you break out each Legion multiple times
Legion Scarab of Officers – Adds +5 Sergeants, which are high-loot mobs
2x Legion Scarabs – Adds +2 Legions
Combine this with:
Map device modifier: +2 Legion encounters
Atlas passive: 100% chance for an additional Legion
Total: 5 Legions per map
3. Atlas Passive Tree
Legion Cluster:
Protracted Battle – Increases Legion duration
Chain of Command – Boosts loot from Sergeants (loot piñatas)
Emblematic – Converts splinters to full emblems
War Supplies – Adds War Hoards
Face Off – Adds Legion generals (optional)
Logistical Support – Extra reward chances from mobs
Pillaged Treasures – Legion chests give extra rewards
Support Clusters:
Scarab Drop Chance Nodes – Sustain Scarabs
Map Drop Nodes – Sustain high-tier maps
No Altar Interactions – Skips Exarch/Eater passives for focus and time efficiency
player began with an Elemental Cobra Lash Deadeye build using Trinity Support. It’s an unusual league starter, not something typically seen on tier lists. While not the fastest clearer, it’s very versatile: strong early, decent scaling, and capable of farming Legion content consistently.
They avoided popular meta builds intentionally, both for fun and to prove that you don’t need flavor-of-the-month skills to succeed.
The initial game plan involved completing the campaign quickly and securing early gear upgrades through lucky drops (like 5-links and valuable gems). This helped speed up early progression significantly. Once maps were unlocked, the player focused on:
Buying a correctly colored 5-link armor with resistances
Using White Wind as a core weapon (great damage, no shield allowed though)
Unlocking Atlas nodes for map drops and Kirac missions
Getting quality on skill gems
Completing all four Labyrinth ascendancies quickly
By around 9 hours in, they had already acquired two Voidstones, pushing well into early red maps.
2. Primary Currency Strategy: Legion Farming
Once in red maps, the player transitioned into a well-planned Legion farming strategy using Dunes maps.
Key points:
Legion was buffed in 3.26, and map crafting could grant an extra Legion encounter even without scarabs (helpful early league).
Cobra Lash, while not super fast, was fast enough to fully clear Legions, which is the most important factor.
The Atlas passive tree was specced into:
-Legion nodes (extra encounters, duration, splinter conversion)
-Searing Exarch for passive currency (no extra investment needed)
Legion farming during the first few days is incredibly profitable due to:
Six-link incubators dropping body armors that sell well early on
Fractured item drops, which can be valuable
Incidental loot from splinters, emblems, fossils, essences, and more
3. Smart Upgrades, Not Overinvestment
The player was very careful about gear upgrades:
Bought Inspired Learning to steal mods during Legion
Crafted a solid elemental dagger using Loathing essences
Made a dense fossil body armor (blocks life mods to pair with life mastery)
Upgraded cluster jewels methodically (Follow Through on mediums, Wind-Up on larges)
Balanced upgrades for both clear and survivability
They also bought boss carries for the remaining Voidstones. While some players avoid this, the decision saved hours of inefficient farming and let them start high-tier mapping faster.
4. Day 3–4: Transitioning Out of Legion
By day 3, Legion profitability dropped as the market was saturated.
They pivoted to a new plan:
Farm Tier 17 maps by running Originator tier 16 maps
Rolled these maps with increased T17 drop chance
Used scarabs to enhance map rewards (scarabs were now more accessible)
Stashed Dunes maps for sale, generating side profit
Built a second tree focused on sustaining and farming T17 maps
Switched to a budget Ward stacking version of Cobra Lash (no belts available yet)
Despite the gear being janky and lacking defense, it had enough damage to farm consistently, even if deaths were frequent.
This farming method is built around Harbingers + Beyond in juiced maps like Basilica or Jungle Valley, with the goal of generating:
Steady income from currency shards
Chase Div cards: The Enlightened (L3), Original Sin, Seven Years Bad Luck, The Damnation
Rare Harbinger drops: Fracturing Shards, Mirror Shards
Bonus mobs from Ritual and Eater of Worlds altars
1. Core Mechanics Breakdown
Harbingers – Currency Engine
Run 3 Harbinger Scarabs + Regency and Warhoard Scarabs (5 total)
Harbingers spawn massive packs → Each one drops currency shards, and has a chance to drop Fracturing or Mirror Shards
Beyond – Div Card Engine
Harbinger mobs die clustered, which naturally triggers Beyond demons
Beyond mobs drop Divination Cards
Taking the node Swarming Hive gives +30% more Div Cards from Beyond mobs
Important: Avoid spawning Beyond bosses
Do NOT take Torn Veil
Instead, take the keystone that prevents Beyond bosses (so demons keep spawning)
Ritual – Bonus Pack Filler
Speccing into nodes guarantees 4 Ritual altars per map
You don’t need to run the altars — just the monster density boosts loot
Ritual mobs also benefit from Beyond and Eldritch Altar interactions
Eater of Worlds – Altars for Quantity & Divines
Eater influence is preferred over Searing Exarch
Prioritize quantity altars, Divine drop altars, and boss altar bonuses (Jungle Valley is best since the boss is simple)
2. Atlas Tree Focus
The tree is designed for:
All 3 Harbinger wheels: Currency multipliers
Full Beyond setup, minus Torn Veil (to avoid bosses)
Ritual nodes: 4 guaranteed altars per map
Eater altars: Focus on quantity bonuses and Divine drop potential
Pack size & explosive modifiers: Increased mod effect = more mobs = better Harbinger scaling
Memory Influence nodes: For high-value “Memory” maps introduced this league
Also includes:
Map sustain nodes
Extra scarab nodes if available
3. Map Modifiers & Investment
High pack size, high quantity, Beyond mod (via device or map roll), possibly Delirium orbs. Deli Orbs optional, synergize well with this strategy. 8-Mod Maps (coming soon in AP’s next guide) will be the ideal scenario for this strat.
