PoE2 Aldur's Legacy Guide: How to Extract Unique Mods Into Runes & Which Uniques Are Worth Destroying (0.5.5)

Quick Answer (TL;DR)

Aldur's Legacy is a Rune added in Path of Exile 2 0.5.0 Return of the Ancients (the Runes of Aldur league, live now through the 0.5.5 Forbidden Rites event). You socket it into an empty Augment Socket on a non-Corrupted Kalguuran or Ezomyte unique — this permanently destroys that unique and hands you a Legacy Rune (e.g. Legacy of Trampletoe) carrying a scaled-down version of one of its modifiers. You then socket that Legacy Rune into any item of the same base type (boots → boots, body armour → body armour) to bring an iconic unique mod to your best-in-slot rare.

• What it does: unique → rune conversion. Sacrifice a Kalguuran/Ezomyte unique, keep one of its powers as a socketable rune.
• Which uniques work: only non-Corrupted Kalguuran/Ezomyte-tagged uniques (poe2db lists 60+ eligible `Legacy of …` results). Corrupted items are locked out.
• The catch: extracted values are nerfed vs the original (Trampletoe's ~30% Overkill area → roughly ~10% on the rune), and the source unique is gone forever.
• How to get the rune: Ezomyte Remnants / Runesmithing recipes (Farrow's league mechanic), the Currency Exchange (after Act 3), league drops, or trade. Early-league it hovered around 30+ Divine Orbs.

If you're deciding whether to burn a valuable unique or buy divines to fund a top-tier extract, the whole decision comes down to which mods are hard to replicate — that's what this guide ranks.

What Is Aldur's Legacy in PoE2?

Aldur's Legacy is one of the headline crafting additions of Patch 0.5.0 Return of the Ancients and the Runes of Aldur league. Its in-game rune text reads verbatim:

"All Equipment: When socketed into a Unique Kalguuran or Ezomyte item, destroys the item to create a Rune imbued with that item's power."

And on socketing:

"Place into an empty Augment Socket in any non-Corrupted Kalguuran or Ezomyte Unique to destroy that Unique and create a new Rune."

In plain terms: instead of vendoring a mediocre Kalguuran or Ezomyte unique, you can extract one of its defining modifiers into a rune and carry it onto gear that's better in every other way. It's the closest PoE2 has come to letting you "keep the good part" of a unique without wearing the whole item.

A note on the name: early league guides (and poe2db's internal string) also call this "Olroth's Legacy" / Aldur's Legacy Rune Warping. They're the same system — GGG standardized on Aldur's Legacy in the client, so that's the term to search and trade by.

How Does Aldur's Legacy Work? (Step by Step)

The system is two stages, and this is exactly where new players get confused — the rune you extract is not the rune you slot into your final gear.

• Obtain an Aldur's Legacy rune (see the acquisition section below).
• Find a non-Corrupted Kalguuran or Ezomyte unique with an empty Augment Socket.
• Socket Aldur's Legacy into that Augment Socket. The unique is permanently destroyed.
• A new Legacy Rune appears in your inventory — named after the sacrificed unique (e.g. Legacy of Trampletoe, Legacy of Blackbraid).
• Socket that Legacy Rune into any item of the same base type (boots for a boots-unique, body armour for a body-armour unique, and so on) to gain a scaled-down version of the original unique's power.

So a single Aldur's Legacy rune produces one Legacy Rune from one unique — this is a one-shot, high-commitment action, not a repeatable roll. Think of the first rune as the "extraction tool" and the Legacy Rune as the finished currency you actually equip.

The finished Legacy of Trampletoe rune above shows exactly what you end up with: a Level 65 boots rune carrying a 10% Overkill-damage area effect — a scaled-down slice of the original Trampletoe boots — plus the tooltip's own warning that once socketed it "cannot be retrieved but can be replaced by other Augment items."

How much power do you lose?

Extracted effects are deliberately nerfed so this doesn't trivialize best-in-slot itemization. The community reference example: Quill Rain's 100% increased Attack Speed comes out closer to ~50% on the rune, and Trampletoe's ~30% Overkill-damage area effect drops to roughly ~10%. Always assume the rune is a fraction of the source unique — the value is in stacking a unique mod onto an otherwise perfect rare, not in cloning the full unique.

How to Get Aldur's Legacy in PoE2

The initial Aldur's Legacy rune comes from the Runes of Aldur league content and the economy:

• Ezomyte Remnants & Runesmithing recipes. Learn Runesmithing from Farrow; as you clear areas you find runic Remnants, carve runes onto them to complete a recipe, and Aldur's Legacy can appear as a reward (game8 notes it can show up on a Remnant with 10 rune slots). This is the "free" route while you level and map.
• Currency Exchange NPC (unlocks after Act 3) — buy it outright with currency once you're in maps.
• League drops & trade. It also drops from league content and is fully tradeable. Early in the league it traded around 30+ Divine Orbs, so it is a premium currency — check poe.ninja for the live price before you commit.

Drop Level: 65. Required Level: 0 (you can slot the finished Legacy Rune early, though the good source uniques come from endgame).

Because the rune itself is expensive and the source unique is destroyed on use, most players either farm the rune through Runesmithing or buy divines to fund both the rune and a high-value target unique rather than gambling a hard-earned drop.

Funding an Aldur's Legacy extract fast? Grab the currency and gear you need instead of grinding for it:

- PoE2 Divine Orbs — the currency Aldur's Legacy runes and top uniques are priced in

- PoE2 Currency & Orbs — exalts, chaos and more to buy your extract target

- PoE2 Boosting & Carries — endgame carries to farm the Kalguuran/Ezomyte uniques worth sacrificing

Which Uniques Are Worth Destroying? (Tier List)

Not every eligible unique is worth burning. Prioritize hard-to-replicate mechanics you can't get anywhere else on a rare — a raw stat you could roll normally is a waste of a 30-Divine rune. poe2db currently lists 60+ `Legacy of …` results, and the pool grows with patches, so this is a value ranking, not the full list.

Blackbraid is the textbook S-tier target: an Ezomyte body armour whose "% of Armour also applies to Elemental Damage" line is a genuinely unique mechanic you can't roll on a rare — exactly the kind of mod worth converting into a Legacy Rune.

Tier	Unique	Slot	Key extracted effect
S	Quill Rain	Bows	Massive increased Attack Speed
S	Blackbraid	Body Armour	% of Armour also applies to Elemental Damage
S	Trampletoe	Boots	Overkill damage dealt in an area
S	Svalinn	Shield	Lucky Block Chance
A+	Wanderlust	Boots	Movement Speed unaffected by slows
A+	Deidbell	Helmet	Warcries explode corpses
A	Bramblejack	Body Armour	Melee Physical Damage reflection
A	Elevore	Helmet	Extra Charm slot & charges
A	Brain Rattler	Mace	Electrocution buildup on all hits
B	Crown of Thorns	Helmet	Defensive / utility mods
B	Starkonja's Head	Helmet	Defensive / utility mods

Rule of thumb: if the mod is a unique mechanic (Blackbraid's armour→ele conversion, Trampletoe's overkill AoE, Svalinn's lucky block), it's worth the rune. If it's a stat you could roll on a rare, skip it.

Common Mistakes & Misconceptions

• "It works on any unique." No. Only non-Corrupted Kalguuran or Ezomyte uniques. That's why players find they can't extract from many favorites — eligibility is tag-gated, and some bases (certain weapon classes players expected, like spears) simply aren't in the pool.
• "I keep the unique." No — socketing Aldur's Legacy destroys the source unique permanently. Do the math before extracting a valuable one.
• "The rune is as strong as the unique." No — values are scaled down (often to roughly half or less). It's a top-up on a great rare, not a clone.
• "Corrupted uniques count." No. Corruption locks the item out of the system entirely, so don't Vaal a unique you plan to extract.
• "I can move the Legacy Rune around freely." Replacing a socketed Legacy Rune can destroy it, same as other runes — treat placement as semi-permanent.

FAQ

What is Aldur's Legacy in PoE2? It's a Rune from the 0.5 Runes of Aldur league that, when socketed into a non-Corrupted Kalguuran or Ezomyte unique, destroys that unique and creates a Legacy Rune carrying a scaled-down version of one of its modifiers, which you can then socket into another item of the same base type.

Is Aldur's Legacy the same as Olroth's Legacy? Yes. "Olroth's Legacy" is the older/internal name (still used by some third-party sites and poe2db's string); the live client calls it Aldur's Legacy. Search and trade under "Aldur's Legacy."

Which uniques can I use Aldur's Legacy on? Only non-Corrupted uniques tagged Kalguuran or Ezomyte. poe2db lists 60+ eligible `Legacy of …` runes and the pool expands with patches, so check its live list before buying a target unique — several popular uniques (and some weapon classes) are not eligible.

How much power does the extracted rune lose? Extracted values are scaled down versus the original — for example Quill Rain's Attack Speed comes out closer to ~50%, and Trampletoe's Overkill area effect to roughly ~10%. Treat it as a partial mod, not a full unique.

How do I get an Aldur's Legacy rune? Through Ezomyte Remnants and Runesmithing recipes (Farrow's league mechanic), the Currency Exchange after Act 3, league drops, or trade. Early in the league it cost around 30+ Divine Orbs — check poe.ninja for the current price.

Should I destroy my unique or buy divines instead? If the unique is cheap and the mod is a hard-to-replicate mechanic, extract it. If it's a valuable chase unique, it's usually smarter to buy divines to fund both the rune and a cheap eligible target than to sacrifice an expensive item.
