Soul Cores are the strongest socketable upgrade in Path of Exile 2 — Vaal artifacts that slot into your gear like Runes but hit far harder. The short answer: Soul Cores drop almost exclusively from the Trial of Chaos (Inscribed Ultimatums), they socket into rune/augment sockets on weapons and armour, and each core gives a different effect depending on whether it's in a weapon or a piece of armour. Most of the 15 base cores are cheap filler, but a handful of named endgame cores — the charge-duplication and crit cores especially — are genuinely build-defining and trade for real currency. This guide lists every Soul Core, what each does, exactly how to farm them, and which ones are actually worth money in the current 0.5.4 Runes of Aldur economy — verified against poe2db, the PoE2 Wiki and current trade data.

Key Takeaways
- Primary source = Trial of Chaos. Each Inscribed Ultimatum run ends with a reward choice that can be a Soul Core or a corrupted item; higher-tier trials drop better cores.
- They fill rune sockets, the same sockets Runes use — you add sockets with an Artificer's Orb (crafted from 10 Artificer's Shards via the Salvage Bench).
- Two tiers exist: 15 base cores (required Level 0, drop level 35) and stronger named "X's Soul Core of Y" cores (required Level 50, drop level 65).
- Weapon effect ≠ armour effect. The same core does one thing in a weapon and something completely different in armour — always check both before socketing.
- Removal is punishing: replacing a Soul Core destroys the old one; an Orb of Extraction recovers the core but destroys the item instead.
- Which are worth money: the charge-duplication cores (Opiloti's Assault / Xopec's Power / Guatelitzi's Endurance) and the crit core (Ticaba) carry the value; most base cores sell for around an Exalted or less.
What Are Soul Cores in PoE2?
Soul Cores are relics of the ancient Vaal empire, and mechanically they're a type of Augment — an item you place into an augment/rune socket on your gear. The PoE2 Wiki describes them plainly:
"Soul Cores are artifacts of the ancient Vaal empire and function as a type of Augment. Augments are items which can be placed into Augment sockets, usually on Equipment items. Once socketed, they can be replaced by other Augments, but cannot be removed by normal means."
— Path of Exile 2 Wiki (poe2wiki.net), Soul Core
That "cannot be removed by normal means" line is the trap that catches new players. Once a Soul Core is in, swapping it in for a different one destroys the core that was already there. Your only recovery tool is an Orb of Extraction, which pulls the core back out intact — but destroys the item it was socketed in. So a Soul Core is a commitment: you socket it into gear you plan to keep, not a leveling weapon you'll replace in two zones.
The reason they're worth the fuss is raw power. Unlike basic Runes, Soul Cores carry effects Runes simply can't roll — flat Spirit, charge generation, Critical Damage Bonus, elemental penetration, attribute-requirement conversion, and defensive layers that scale off your Energy Shield or Armour. In the right slot, one core can be a bigger upgrade than a whole tier of gear.

How Do You Get Soul Cores in PoE2?
There is essentially one reliable faucet, and a couple of minor ones:
- Trial of Chaos (the main source). You enter with an Inscribed Ultimatum — a consumable that drops from enemies through the campaign and endgame — and clear stacked challenge rooms. At the end, the Trialmaster offers a reward that is frequently a Soul Core (or a corrupted item). This is the same activity you run to unlock your Ascendancy points, so you'll farm cores and progression at the same time. See our full Trial of Chaos guide for the room tiers and boss fragments.
- Higher tiers = better cores. Low-level trials hand out the base (Level 0) cores; the required-Level-50 named cores drop at monster level 65+, so you need high-tier Inscribed Ultimatums and endgame area levels to see them at all.
- World drops. Cores can trickle out of general endgame content, but the rate is low enough that nobody farms it deliberately.
- The Currency Exchange (buying). Soul Cores have their own row on the Currency Exchange bulk market. If you need one specific core, buying it is almost always faster than praying to the Trialmaster.
"If you get Soul Cores or rewards your build does not need, trade them through the Currency Exchange and use that value to buy the cores or upgrades you actually want."

How Do You Socket a Soul Core?
Soul Cores go into the same sockets as Runes, and most gear has zero sockets by default. You create them yourself:
- Salvage Bench → Artificer's Shards. Salvaging any already-socketed gear at the Salvage Bench (unlocked in Act 1) gives Artificer's Shards; 10 shards auto-combine into one Artificer's Orb.
- Artificer's Orb. Right-click it, left-click your item, and it adds an empty socket (up to that base's cap — 2 for body armour and two-handed weapons, 1 for most one-handers and other armour pieces). Full breakdown in our Artificer's Orb guide.
- Vaal Orb (risky). Corrupting gear with a Vaal Orb can add a socket beyond the normal cap — but corruption is final and can brick the item. Only gamble on expendable bases.
Weapons first. For almost every build, the biggest gains come from a weapon socket (penetration, crit, charges), then body armour and helmet for defence, with gloves/boots/shields/foci used to patch resistances or utility.

Every PoE2 Soul Core and What It Does
Here are the 15 base Soul Cores (required Level 0, drop level 35). Remember: the weapon effect and armour effect are different, so many cores are used exclusively in one or the other.
| Soul Core | Weapon effect | Armour effect |
|---|---|---|
| Tacati | 15% chance to Poison on Hit | +11% Chaos Resistance |
| Citaqualotl | 30% increased Elemental Damage with Attacks | +5% to all Elemental Resistances |
| Topotante | Attacks Penetrate 15% Elemental Resistances | 25% increased Elemental Ailment Threshold (boots) |
| Azcapa | +15 to Spirit | 10% increased Gold Quantity from slain enemies (gloves) |
| Ticaba | +5% to Critical Damage Bonus | Hits against you have 20% reduced Critical Damage Bonus |
| Opiloti | 15% chance to cause Bleeding on Hit | 20% increased Charm Charges gained (helmet) |
| Jiquani | Recover 2% of maximum Life on Kill | 3% increased maximum Life (body armour) |
| Zalatl | Recover 2% of maximum Mana on Kill | 3% increased maximum Mana (helmet) |
| Puhuarte | 30% increased Flammability Magnitude | +1% to Maximum Fire Resistance (gloves) |
| Tzamoto | 30% increased Freeze Buildup | +1% to Maximum Cold Resistance (helmet) |
| Xopec | 30% increased chance to Shock | +1% to Maximum Lightning Resistance (boots) |
| Quipolatl | 5% increased Attack Speed | 15% reduced Slowing Potency of Debuffs (boots) |
| Atmohua | Convert 20% of Requirements to Strength | Convert 20% of Requirements to Strength |
| Cholotl | Convert 20% of Requirements to Dexterity | Convert 20% of Requirements to Dexterity |
| Zantipi | Convert 20% of Requirements to Intelligence | Convert 20% of Requirements to Intelligence |

The three attribute-conversion cores (Atmohua/Cholotl/Zantipi) deserve a callout: "Convert 20% of Requirements to Strength/Dex/Int" is how attribute-stacking and off-class builds equip gear they otherwise couldn't wear. They're niche but build-enabling — pair one with a chase amulet like Astramentis and the stat-stacking archetype opens up.
The named endgame cores (required Level 50, drop level 65)
These are the "X's Soul Core of Y" variants — rarer, higher drop level, and where the money is. The standouts:
| Named Soul Core | Effect | Why it matters |
|---|---|---|
| Opiloti's Soul Core of Assault | 50% chance to gain an extra Frenzy Charge when you gain one | Doubles Frenzy generation — huge for attack/crit builds |
| Xopec's Soul Core of Power | 50% chance to gain an extra Power Charge when you gain one | Power-stacking crit/spell builds |
| Guatelitzi's Soul Core of Endurance | 50% chance to gain an extra Endurance Charge when you gain one | Tanky/armour builds wanting max Endurance |
| Atmohua's Soul Core of Retreat | Stun + Ailment Threshold equal to 15% of max Energy Shield | Best-in-slot for ES/CI defensive setups |
| Hayoxi's / Zalatl's / Topotante's (Heatproofing / Insulation / Dampening) | +40% of Armour also applies to Cold / Lightning / Fire Damage | Armour-stacking tanks converting Armour into elemental mitigation |
| Quipolatl's Soul Core of Flow | 8% increased Skill Effect Duration + 8% Cooldown Recovery | Duration/cooldown builds |
Which Soul Cores Are Actually Worth Money?
This is where most guides stop short. Here's the honest breakdown for 0.5.4 Runes of Aldur (for currency context, 1 Divine Orb trades for roughly 390–420 Exalted right now — verify live, the ratio drifts all league):
- Filler (≈1 Exalted or less): most base cores. The single-resistance and minor-recovery cores (Puhuarte, Tzamoto, Zalatl, the max-res-by-1% cores) are common trial rewards and sell cheap. Don't hoard them — vendor or bulk-sell.
- Solid mid-value: Citaqualotl (+5% all-ele-res armour is a great generic defensive core), Azcapa (+15 Spirit for spirit-hungry builds), Ticaba (+5% Crit Damage Bonus in a weapon). These move steadily because half the builds in the game want them.
- The premium tier: the charge-duplication trio — Opiloti's Assault, Xopec's Power, Guatelitzi's Endurance — plus Atmohua's Retreat for ES builds. These are build-enablers, drop only at level 65+, and are the cores people actually open their wallets for. Expect them to run several to tens of Exalted, with the most in-demand ones pushing toward a Divine during meta spikes.
Value rule of thumb: effect scarcity + build demand = price. A core that only one archetype wants but needs (charge duplication, ES threshold) beats a core everyone can use but nobody desperately needs. Because Soul Cores trade on the bulk Currency Exchange, prices are liquid and move fast — always price-check live before you buy or dump, exactly like you would when selling any item.
Buy the Cores (and the Currency) Instead of Grinding Trials
Farming the Trial of Chaos for one specific Level-65 core can take dozens of runs — the reward is a random core or a corrupted item, not the one you want. If you know the core your build needs, buying it (or buying the currency to afford it) is the efficient play:

Frequently Asked Questions
What's the difference between a Soul Core and a Rune in PoE2? Both go in the same rune/augment sockets, but Soul Cores are Vaal artifacts with a wider, stronger pool of effects — flat Spirit, charge duplication, crit, penetration and ES-based defences that Runes can't roll. Runes are common and craftable via runeforging; Soul Cores drop from the Trial of Chaos and are generally the bigger upgrade.
Can you remove a Soul Core once it's socketed? Not for free. Socketing a new core into an occupied socket destroys the old one. The only way to recover a socketed core is an Orb of Extraction, which pulls the core out intact but destroys the item it was in. Treat socketing as permanent and only commit cores to keeper gear.
Where do Soul Cores drop? Overwhelmingly from the Trial of Chaos — you enter with an Inscribed Ultimatum and the Trialmaster's end reward is often a Soul Core. Higher-tier trials at higher area levels are the only way to get the required-Level-50 named cores (drop level 65).
Do Soul Cores have different effects in weapons vs armour? Yes — almost every base core has a completely different weapon effect and armour effect. Tacati, for example, is "15% chance to Poison" in a weapon but "+11% Chaos Resistance" in armour. Always read both lines before you socket.
Which Soul Core is the best? There's no single best — it depends on your build. The most valuable and sought-after are the charge-duplication cores (Opiloti's Assault, Xopec's Power, Guatelitzi's Endurance) and Ticaba for crit. For generic defence, Citaqualotl (+5% all elemental resistances) is one of the safest picks.
Are Soul Cores worth buying with real currency? The base cores aren't — they're cheap trial byproducts. The named Level-65 cores are, because they're build-defining and rare. If your build hinges on a charge-duplication or ES-threshold core, buying it on the Currency Exchange saves hours of Trialmaster RNG.
