Path of Exile's 3.26 update, Secrets of the Atlas, introduces a unique and powerful new mechanic to the game: Mercenaries of Trarthus. These companions act like permanent, customizable allies throughout your journey, from early Acts to the pinnacle of endgame content. With the right mercenary archetypes by your side, you can drastically enhance both your survivability and damage potential during endgame farming and bossing.

Each mercenary is built from a predefined archetype, coming with stat preferences, a random set of skill gems, and equipment pools. Choosing the right archetype makes a huge difference in high-tier mapping, Uber bosses, and League farming. Below is a ranked list of the best mercenary archetypes for endgame in 3.26.

7. Manyshot - Clone Archer

· Stats: Dexterity

· Key Skills: Vaal Ice Shot, Mirror Arrow, Grace, Hatred

Though not a heavy-hitter, the Manyshot archetype excels as a free aura bot. With Hatred and Grace equipped, it offers cold damage scaling and high evasion, freeing the player from reserving these auras themselves.

Use it to boost your early evasion-based builds or stack with your aura setup for extra power. While its damage is mediocre, the clone-summoning and area slows from cold skills can help control the battlefield.

6. Bladecaster - Blade Vortex Spellcaster

· Stats: Dexterity / Intelligence

· Key Skills: Ethereal Knives, Bladefall of Trarthus, Aspect of the Spider, Grace

The Bladecaster is a hybrid DPS/support archetype, combining reliable AoE with Aspect of the Spider, a debuff that slows enemies and increases damage taken. If you're running an evasion-based or spell build, this mercenary pairs nicely with your kit.

If you buy Path Of Exile Items, which are evasion/resist gear, the Bladecaster will be surprisingly sturdy and adds meaningful damage in mob-dense maps.

5. Cruel Mistress - Enemy Debilitator

· Stats: Intelligence

· Key Skills: Despair, Void Sphere, Dark Pact, Zealotry

For chaos or dot-based builds, the Cruel Mistress offers amazing enemy debuffs. She casts Void Sphere to group enemies and applies curses like Despair for chaos scaling.

If she rolls with Zealotry or Envy, casters in particular will benefit from increased crit and chaos scaling. She's ideal for builds focused on Soulrend, Essence Drain, or Corrupting Fever.

4. Fallen Reverend - Curse Tank Aura Bot

· Stats: Strength / Intelligence

· Key Skills: Raise Spectre of Transience, Desecrate, Wrath, Zealotry

The Fallen Reverend is one of the best utility mercenaries thanks to its aura stacking and the ability to equip game-changing uniques. With access to Sign of the Sin Eater, for example, it can absorb elemental ailments from the player, perfect for hardcore or ailment-vulnerable builds.

Look for ones that roll Wrath and Zealotry to juice your elemental or caster damage. Stack life and resist to keep it alive, and you've got an endgame companion that pays for itself tenfold.

3. Eruptor - Melee Fire Tank

· Stats: Strength

· Key Skills: Volcanic Fissure, Consecrated Path, Molten Shell, Flamelink

If you're tired of your merc dying mid-map, the Eruptor is your go-to tanky carry. With innate high armor, Determination, and Molten Shell, this mercenary can survive most map content and clear mobs on its own.

Equip it with a two-handed weapon, and the Volcanic Fissure of Snaking will tear through enemy packs. Flamelink also grants shared fire damage, making it ideal for fire-based melee or spell builds.

2. Flaming Charlatan - Fire Aura Support

· Stats: Strength / Intelligence

· Key Skills: Purifying Flame, Scorching Ray Totem, Anger, Herald of Ash

The Flaming Charlatan is a fire support specialist. With Anger and Herald of Ash, it boosts fire damage, spreads burning via overkill effects, and can even act as a secondary fire damage dealer.

This archetype is ideal for Righteous Fire, Fire Trap, Flameblast, or Explosive Arrow builds. Combine with gear like Ignite Prolif or Replica Emberwake for extra synergy.

1. Kineticist - All-Around Support & Damage

· Stats: Strength / Dexterity / Intelligence

· Key Skills: Kinetic Blast, Elemental Weakness, Flame Wall, Haste

The Kineticist is hands-down the most versatile and powerful mercenary for endgame. Its triple-stat spread allows it to equip nearly any item in the game, from Asenath's Gentle Touch to Coiling Whisper and Doryani's Prototype.

On top of that, it brings:

· Debuffs (Elemental Weakness)

· Movement buffs (Haste)

· Projectile synergy (Flame Wall + Kinetic Blast)

This archetype not only keeps up with the player, but it also amplifies everything from AoE clear speed to endgame boss DPS. Players optimizing for Maven, Shaper, or Uber Elder runs should aim to recruit a Kineticist merc and load them up with tailored endgame gear.

Final Thoughts

The Mercenaries of Trarthus mechanic in Path of Exile 3.26 has added a fresh dynamic to both solo and group play. Whether you're looking for extra auras, crowd control, curse application, or a full-on extra damage dealer, there's an archetype to match your build.

While each archetype has its niche, Kineticist and Eruptor stand out for raw endgame performance. Support builds will benefit greatly from Fallen Reverend or Flaming Charlatan, while the Cruel Mistress adds valuable debuff control.

As always, gear and POE currency matters-keep your mercs alive and buy well-equipped, and they'll carry you through even the harshest corners of Wraeclast.
