The 0.5 patch for Path of Exile 2 brings a wild new crafting mechanic that completely changes how players approach unique items. Aldur's Legacy, aka Olroth's Legacy, is a freshly added currency that lets you rip a modifier out of a Kalguuran or Ezomyte unique and socket it into another item of the same class. Suddenly, those mediocre uniques sitting in your stash with one ridiculous modifier become extraction fodder for your favorite rares. This guide walks through how Olroth's Legacy crafting system works, which unique bases are worth hoarding, and which modifiers are likely to dominate the league economy.
How Aldur's Legacy (Olroth's Legacy) Works in PoE 2 0.5?
Before getting into specific items, it helps to know exactly what this Aldur's Legacy (Olroth's Legacy) currency does and what its limits are.
The Core Process: Aldur's Legacy destroys a Kalguuran or Ezomyte unique, pulls one of its unique modifiers, and converts that modifier into a socketable rune. The rune can then be placed into another item of the same class.
Same Class Restriction: A modifier extracted from a body armor only fits into another body armor. A two-handed mace mod stays on two-handed maces. Bow modifiers stay on bows. You can't take a Quill Rain attack speed mod and put it on a sword.
Rare and Unique Compatibility: Based on early information from the developers, these runes can be socketed into both rare items and other unique items of the matching class.
Scaled Values: Some modifier values will be reduced during the conversion process. Without those adjustments, taking the strongest mod off a unique and pasting it onto a top-tier rare with no drawback would be flat-out broken.
Extraction Randomness: The rune you receive is random from among the unique's modifiers. A unique with five mods gives you roughly a one-in-five shot at the one you actually want, so expect to burn through multiple bases before hitting your target.

Now that the candidate list is on the table, let's get into which modifiers are actually worth chasing.
Best Unique Bases & Modifiers for Aldur's Legacy Runecrafting
Not every rune will be equally valuable. The top-tier picks are the ones whose modifiers are otherwise impossible to obtain or wildly stronger than what crafting allows. Here are the best picks broken out by gear slot.
Best Weapons (Bows & Maces)
Quill Rain (Bow) - Possibly the single strongest rune candidate in the entire system. Its 100% increased attack speed is a local modifier, and pulling it free from the 40% less attack damage multiplier produces the fastest-attacking bows ever seen in PoE 2. Even at 50% scaled value, this would be transformative. Local attack speed gets multiplied by every other source of attack speed on your build, which means stacking it on top of a high-tier rare bow can nearly double your DPS while making the build feel snappier.
Hog Hunt (Two-Handed Mace) - Carries a 15% to critical hit chance modifier, applied as base crit. A two-handed mace with 10 base crit jumps to 25 with this rune, which is absurd scaling for crit-based mace builds. Class-restricted to two-handed maces, but the source item is essentially a one-alc drop, so destroying it costs nothing.
Olroavasara (Two-Handed Mace) - Provides 30% local attack speed plus a stacking maximum lightning damage line that applies to all skills, including heralds and triggered casts. Slotting this into a high-damage rare mace creates massive multi-skill scaling.
Rimnor's Hymn (Two-Handed Mace) - Slam skills you use yourself cause an additional aftershock. This is a build-defining line for slam Titans, mace Martial Artists, and any aftershock-focused setup. The source unique exists almost entirely for this single modifier.
Iron Bound Warden (Bow) - Returns arrows after piercing fully broken armor. For Lightning Arrow players, this nearly doubles your effective damage output on broken targets.
Best Body Armors
Blackbraid (Body Armor) - 150% of armor also applies to elemental damage. Crafted body armors cap out at 50% of this stat, so adding this rune triples that value. Combined with a properly rolled rare, you can reach roughly 200% conversion for armor-stacking builds. Even with a 66% nerf, the floor is still better than what crafting allows.
Best Helmets
Keeper of the Arc - Alternates less damage from hits and damage over time. Even scaled to 20% per side, this would still be worth using over almost any other helmet rune, because it's just a rune slot and doesn't lock you into the Keeper of the Arc base.
Ezomyte Peak - Increased area of effect, universally good for nearly every build type. A safe, non-niche pick.
Alpha's Howl - 100% speed (action speed). Most valuable on energy shield base helmets, where it pairs with high-tier defensive rolls. Expect this to be one of the most popular extraction targets at league start.
Starkonja's Head - Strong defensive and crit lines for ranger and ranged builds.
Crown of Thorns / Bramblejack - Strong synergy with the new thorns rune introduced this league, which could open up an entire archetype.
Unwavering Stance candidates - Cannot be stunned is hard to nerf without adding a downside, making it an easy quality-of-life pick for almost any build that lacks stun mitigation.
Best Boots
Wanderlust - Movement speed unaffected by slows. This effectively turns any class into Pathfinder for the purposes of slow immunity, ignoring chilled ground, 50% chill, wet monster effects, and similar slow sources.
Trample Toe - Deals 30% damage to enemies within 2m of an enemy kill. A massive clear-speed booster, particularly useful for builds running single-target-focused skills like Flicker Strike that struggle with mapping efficiency.
Briskwrap / Foxshade - Solid mobility and evasion options for builds that need extra movement scaling.
Best Gloves
Allelopathy - Plus one charm slot. With Rage Blood being added in 0.5, charm uptime becomes far more important, pushing this rune into high-priority territory.
Irongrasp - Various utility and offensive options depending on which modifier transfers.
Global culling strike candidates - Approximately equivalent to 2 Witchhunter ascendancy points for one glove socket, which is a strong return on a single rune.
Best Shields
Svalinn - Chance to block is lucky. Removing this from the otherwise weak Svalinn base and slotting it into a properly itemized shield (or even another unique shield) creates absurd block stacking. If the downside doesn't carry over, this could define a block meta.
Sunderboar Pillar - 1% of damage as fire damage per 1% chance to block. Pairs beautifully with shield-throw and Captain America-style builds, especially when combined with shields like Nightfall of Fortress that already grant fire conversion.
Soaring Midnight - Tied to shield throw and slam combinations. Since the skill scales off the shield's armor value rather than your weapon, the build flexibility this enables is huge.
Best Caster Picks
Adorned Egos - Pinnacle of Power is the modifier worth chasing here. If you can socket Pinnacle of Power into any caster item, the result is potentially insane scaling for power-charge-based builds. Without it, the rune is mostly worthless, so the gamble is high-risk.
Trenchtimber +skills line - A +2 lightning skill rune combined with the base item could reach +6 to shock mages, which is a major damage boost for minion-heavy builds.
