PoE 3.29 Luminary Skills, Mercenary, Uniques & Build Guide

Path of Exile 3.29 Curse of the Allflame league reintroduces one of the community's most talked-about mechanics from a previous league: the Mercenaries of Trarthus. This time around, they are being folded into the core game, and Grinding Gear Games has paired the return with a brand-new Ascendancy class for the Scion called the Luminary. Together, these two additions give players a fresh way to add a second combatant to their build, complete with gear slots, skills, and Atlas-wide progression. This guide walks you through what the Luminary is, how its passives work, how Mercenaries and link skills work with it in the core game, and how to build around this powerful new system.

PoE 3.29 Luminary & Mercenary Build Guide

Mercenaries of Trarthus are wandering swords-for-hire that appear across Wraeclast from Act 3 onward. Any character can duel them, wager gold on a piece of their gear, win the item, and take the Mercenary along as an ally for a limited number of areas. The Luminary Ascendancy Class flips this temporary alliance into something permanent, but only for Scion players. Together, Mercenaries function almost like a "fifth ascendancy" for every build, offering auras, buffs, or outright killing power, while the Luminary transforms mercenary management into an entire build archetype.

With the basics out of the way, let's look at how Mercenaries appear and how the duel system works.

The Luminary Ascendancy Class for Scion

The Luminary is the second brand-new Ascendancy class added to the Scion within six months, described in-game as a natural leader who lights the way for others to follow. Unlike other ascendancies, the Luminary is centered entirely around a single concept: keeping a permanent Mercenary of Trarthus at your side and building your character around that ally.

Gameplay Mechanics

For anyone unfamiliar with the returning system, Mercenaries are temporary sword-for-hire allies you encounter in maps. You can gear them up, hand them uniques, and scale their power. However, for regular characters they only stick around for a limited number of areas. The Luminary flips this on its head, you can permanently keep up to three Mercenaries at once, with one being active in combat while two remain in reserve in your hideout or town.

Two Core Playstyles

The Luminary opens up two very distinct build directions:

Merc-Carry (Aurabot Playstyle): You act as the support, feeding your Mercenary auras, link buffs, and defensive layers while they do the killing. Shield charge around the map while your Kineticist or Bow merc deletes packs.
Self-Damage With Merc Bodyguard: You are the damage dealer, and the Mercenary tanks hits for you through damage diversion and taunt mechanics while providing auras and utility.

The class is a Scion start, which means it gets its ascendancy on the first Labyrinth rather than the second - a nice quality-of-life shift compared to the older Ascendant setup.

Noble Blood: Permanent Hiring

The moment you Ascend as a Luminary, you can allocate the Noble Blood passive. This is the core feature of the class: it lets you permanently hire any Mercenary you find in Wraeclast.

You can keep up to 3 permanently hired Mercenaries at once.
2 are held in reserve in Towns and Hideouts.
1 acts as your active ally in combat.
You can freely swap the gear on permanently hired Mercenaries, something regular hired Mercenaries do not allow.

This alone opens up an enormous amount of build variety, because you now have effectively a second character to equip and gear alongside your Scion.

Equipping Unique Items on Your Mercenary

By default, permanently hired Mercenaries cannot wear Unique Items. However, specific Ascendancy passives change that:

Certain passives allow your Mercenary to equip specific categories of Uniques.
The Legendary Arms passive empowers Mercenaries that have many different Unique Items equipped, rewarding fully kitted-out builds.

With those rules in mind, the direction of your Luminary build depends heavily on which support passives you pick up.

Luminary Ascendancy Passive Skills

The Luminary tree is structured to force certain choices early, then branch out into support-focused or damage-focused directions. You have limited points to spend, so full customization across every node is off the table.

Starting Node - Noble Blood

The starting point of the tree grants 15% increased damage to your mercenary and their minions, plus 5% light radius. The next node up is Noble Blood, which allows you to permanently hire a mercenary. This isn't freely allocated - you must level it through your first ascendancy, meaning you have around six more points to distribute after this baseline is set.

Legendary Arms - Unique Item Scaling

By default, permanently hired Mercenaries cannot wear Unique Items. The Legendary Arms notable changes that, allowing your Mercenary to equip unique weapons, shields, and quivers, while providing 8% more damage per unique item they have equipped. Notably, unique body armor is not available even with this node, meaning Doryani's Prototype cheese setups are off the table.

Oath of Fealty - Link Skill Powerhouse

This node makes link skills less costly and gives them infinite attachment duration. If your mercenary dies, the link owner no longer dies with them, a lifesaver in hardcore play. This is one of the strongest support-path picks.

Golden Glory - Light Radius Scaling

Increases and reductions to light radius also apply to the effect of your link skill buffs on your mercenary. Combined with the base 5% light radius from the starter node, this opens up light-radius stacking as a build vector.

Support-Your-Mercenary Path

Oath of Fealty - Enables permanent link uptime and safety.
Golden Glory - Scales link buff strength through light radius.
Legendary Arms - Multiplies damage through stacking uniques on the merc.

This route turns your Scion into a buff-bot while your fully geared mercenary swings through packs and bosses.

Bodyguard/Aura Path

Loyal Bodyguard - Mercenary life over your own means 20% of hits are taken from their life first. If your merc's life is lower, they recoup 40% of damage as life.
Bestowed Knighthood - Your merc taunts on hit and gains increased effect of non-curse auras from your skills.

This is ideal for glass-cannon Scion builds where the merc soaks hits and amplifies aura output. It also pairs well with aura-focused mercs you might already run into during mapping.

How Does the Mercenary Mechanic Work?

Mercenaries function almost like a "fifth ascendancy" for every build. Any character can duel one, wager gold on their gear, and take the winner along as an ally.

How To Get Mercenary - Where and When Mercenaries Appear

Mercenaries begin appearing from Act 3 in Sarn and continue into the endgame.

Guaranteed Campaign Spawns

You are guaranteed to run into one in each of the following campaign zones:

The Sceptre of God (perfect for Luminary starters who want their first permanent merc immediately)
The Grand Arena
The Ridge
The Hidden Underbelly

Mercenaries found in these guaranteed campaign zones will not carry any Rucksack items, so save your gold-fueled wagers for the ones you meet organically.

Map Zone Encounters

Mercenaries appear throughout mapping and can carry Rucksacks with additional loot. These are the ones worth wagering serious gold on, and where the Warrant system becomes valuable.

The Duel and Wager System

When you meet a Mercenary, you get a full overview of their equipped gear and skills before starting the fight. Per the Trarthan Code, you have the right to wager for one item they are carrying. You then stake some of your gold, and the duel begins:

Lose the fight: The levied gold is forfeited and the Mercenary teleports away.
Win the fight: You claim the wagered item, and the Mercenary joins you as an ally for a number of areas.

How Hired Mercenaries Scale

A hired Mercenary's passive stats and skills scale up to the level of your current area, capped at level 68. The item level of gear you can equip on them, however, is still limited by the area level where you first found that Mercenary, so higher-level zones produce better long-term allies.

Some Mercenaries provide powerful auras and buffs, while others do most of the killing for you. Unlike the original Mercenaries of Trarthus league, having one along does not count as a party member, so monster life, item quantity, and item rarity are not affected.

Once you have a Mercenary you like, the next question becomes how to keep working with them, and that is where Warrants come in.

Important Differences from Mercenary League

Unlike the original Mercenaries of Trarthus league, having one along does not count as a party member, so monster life, item quantity, and item rarity are not affected. This makes them pure extra power rather than a tradeoff.

The Warrant System: Chasing the Mercenary You Want

If a Mercenary you meet in a Map area is not offering something you want, you can request their Warrant. A Warrant is a promise to duel that specific Mercenary again on a later Map, keeping the same set of skills but rolling a new set of items.

Key rules to remember about Warrants:

Each Mercenary will only grant a Warrant once, so you cannot farm the same one endlessly.
Warrants are tradable between players, which opens up an entire economy around desirable skill loadouts.
Rucksacks in endgame Maps can no longer generate Orbs of Transmutation or Orbs of Augmentation, so the value now sits mostly in the gear and the Warrants themselves.

Now that you know how to acquire and re-summon Mercenaries, let's look at the class that lets you keep them by your side forever.

Luminary Atlas Passive Tree and Trarthan Scarabs

Grinding Gear Games has added full Atlas Tree and Scarab support for Mercenaries, so you can farm them the same way you farm any other core mechanic.

Atlas Passive Notables Worth Knowing

Loot and Pillage – Mercenaries have a chance to drop all of their items when defeated, rather than only the item you wagered for. This is huge for gear farming and for feeding Warrants into trade.
Additional passives let you target specific Mercenary categories to appear more often in your Maps.

The Trarthan Scarab Line-Up

Four Scarabs are being added to support Mercenary strategies:

Trarthan Scarab – Area is inhabited by a Mercenary.
Trarthan Scarab of Infamy – Mercenaries found in the Area are Infamous, and they appear alongside two Wild Mercenaries. A tougher fight, but a much richer payout.
Trarthan Scarab of Renown – All equipment items on Mercenaries in the Area are Unique. Combined with Loot and Pillage, this becomes a fantastic Unique-farming engine.
Trarthan Scarab of Surprising Alliances – Wild Rogue Exiles have a 50% chance to be accompanied by a Wild Mercenary, and Wild Mercenaries scale in difficulty for each additional one in the Area.

Searing Exarch Altar Modifiers have also been added that drop Mercenary Scarabs, giving you passive supply while running juiced maps.

Rewards Returning to Mercenary Encounters

Several Unique items are once again exclusive to Mercenary drops, and have been pulled out of the core drop pool:

Azadi Crest
Binds of Bloody Vengeance
The Ghastly Theatre
Hand of Heresy
Howlcrack
Scornflux

Trarthan Gems are also no longer possible rewards from Gem Chests in Heist, they are again obtained through Mercenary encounters. If you want any of these, you now have a clear farming target.

PoE Link Skills - The Heart of Merc-Carry Builds

Link skills are what make the Luminary's merc-carry playstyle so powerful. Here's a rundown of what each does when paired with a mercenary.

Damage-Scaling Links

Flame Link – Grants the merc added fire damage equal to 5% of your maximum life. Pairs beautifully with life stackers using Apostate for face-melting damage output.
Destructive Link – Gives your merc crit chance equal to your main hand weapon. Run a high crit weapon and max out their crit, likely the go-to damage link for many setups.
Frigid Bond – Applies cold dot around your merc. Combined with movement speed scaling, this can be absolutely wild.

Defensive Links

Soul Link – Link target takes less damage, with 30% of hits against them taken from your energy shield first. Perfect for aurabots stacking massive ES pools.
Protective Link – Gives the link target chance to block equal to your max block. Pair with Versatile Combatant and the new shield block corruptions for a nearly unkillable merc.
Vampiric Link – Keeps you alive when running the aurabot direction.

Trigger Link

Intuitive Link – Lets your supported spells trigger through your mercenary. Since Oath of Fealty negates the "die when link target dies" downside, this becomes a real option for hybrid setups.

Best Uniques for the Luminary

Several uniques stand out for merc-carry builds thanks to the ability to swap gear on your permanent mercenary.

The Hallowed Monarch

This helm is likely to become the go-to item for merc builds. It provides 35% to all elemental resistance, allows linked skills to target damageable minions, makes linked minions take 65-75% less damage, and most powerful of all on killing a rare monster, a random linked minion gains its modifiers for 60 seconds. That last effect is essentially Headhunter for your merc.

Hands of Friisia (Gloves)

Increased effect of non-curse auras from your skills while you have a Link target. Excellent for aurabot setups.

Scepter of Benevolence

Non-unique utility flasks you use apply to Link targets, allowing you to flask-buff your merc.

Enmity's Embrace

A Vermillion Ring valuable for its up-to-200% fire resistance override effect on allies, popular in aurabot merc-carry setups. Used heavily in the original Mercenary league to enable stupidly high resistance capping on mercs running Doryani's Prototype variants.

Kingmaker

50% crit multi, 10% fortify, and calling strike make this an obvious pick for a merc that's doing the damage.

Luminary Build Directions for 3.29

With the basic knowledge of the Luminary and Merc covered, let's put everything together into practical build recommendations. Here are three build archetypes that fit naturally with the new Ascendancy and Mercenary system:

1. Aura-Stacker Merc-Carry Luminary

Uses a Kineticist merc with KB of Clustering as the primary damage dealer.
Focus Scion passives on Oath of Fealty and Golden Glory for permanent link uptime and buff scaling.
Run Flame Link with Apostate life stacking to give the merc massive flat fire damage.
Layer aura effect through corruptions and shield charge around while the merc kills everything.
Hallowed Monarch is the endgame chase item for both tankiness and rare-modifier stealing.

2. Life-Stacking Flame Link Scion

Stack maximum life through Kaom's Heart, Apostate, and life-focused rares.
Give merc close to 2k flat fire damage via Flame Link, making almost any skill viable.
Combine with Foulborn Red Dream, Bloodlines options, and Gull for shrine effects if available.
Cheap to gear the merc — Crystallized Omniscience plus random +attribute gear plus a Piscator's Wand covers the basics.

3. Bodyguard Damage Luminary

The Scion runs a strong self-damage skill while the Mercenary contributes secondary damage and taunts.
Focus on Loyal Bodyguard and Bestowed Knighthood for defensive layers.
Use forbidden flesh/flame jewels for extra scaling since Luminary is a normal ascendancy.
Best for players who want flexibility across mapping and bossing phases.

Farming Loop for Luminary Builds

For any of the above directions, the recommended Atlas loop looks like this:

Allocate all Mercenary-related Atlas passives, especially Loot and Pillage.
Run Trarthan Scarab plus Trarthan Scarab of Renown for Unique-covered Mercenaries.
Use Warrants to lock down specific skill loadouts you want to hire permanently.
Trade duplicate Warrants for currency or specific Mercenaries other players are offering.
Farm Searing Exarch Altars for passive Mercenary Scarab supply.

Luminary League Start Considerations

Starting the league directly as Luminary can be rough because you need to find a good mercenary before your build fully comes online. Two common approaches solve this:

Zoomancer to Luminary: Start as Scion Ascendant with a Necromancer + Elementalist combo running minions like Absolution, then respec into Luminary once you find or buy a good merc.
Trade for a Warrant: Since Warrants are tradable, you can skip the RNG entirely by buying the Warrant of a strong mercenary. You'll still need to defeat them in the duel, so have some backup gold and a working build first.

The Sceptre of God guaranteed spawn means you can technically have a permanent merc as early as Act 3, giving you an ally that scales with the campaign.
