The Crafting Codex

IItem Anatomy

Every craft starts with an item. Every item is a base (its physical class — Rattling Sceptre, Science Scale Gloves, Gemini Bow) at a particular item level (ilvl), with a particular rarity that gates how many modifiers it can carry, and those modifiers split into prefixes and suffixes.

Rarity Ladder

Prefixes & Suffixes

A Magic item can have up to 1 prefix and 1 suffix (2 total). A Rare item can have up to 3 prefixes and 3 suffixes (6 total). The two sides are functionally independent: a slam that targets prefixes never touches suffixes, and vice versa. Most "deterministic" crafting in PoE2 boils down to controlling which side an orb hits.

As a rough rule of thumb (always cross-check against PoE2DB before any real craft): damage-shaped modifiers tend to be prefixes (flat damage, % damage, +levels, life, energy shield, mana), while stats-shaped modifiers tend to be suffixes (resistances, attributes, attack speed, cast speed, crit chance, recovery rates). There are exceptions — e.g. spirit on a sceptre is a prefix; movement speed on boots is a suffix — and you should not memorise the layout. The reflex you want is "before I slam this, I check the mod pool on PoE2DB."

Item Level & Modifier Tier Gates

Every modifier has a minimum item level at which it can roll, and the tier of that modifier scales with item level. T1 modifiers (the highest tier) almost always require ilvl 80+; many need ilvl 82. T2 is typically ilvl 75. Lower tiers roll at lower ilvls. Below the minimum, that modifier cannot appear on the item at all.

This matters for two reasons. First, when buying a base, you usually want ilvl 81 or 82 — the cheapest items that can still roll T1 on the modifiers you care about. Second, the Greater and Perfect tiers of basic currency orbs guarantee a minimum modifier level (Greater = mod level 35; Perfect = mod level 50 or 70, depending on the currency), which removes the lowest-tier garbage from the result pool. See §III.

Implicit vs. Explicit Modifiers

Implicit modifiers are tied to the base type itself (e.g. "+25 to maximum Mana" on a Synthesised Amethyst Ring). They do not count towards the 6-modifier limit and cannot be modified by ordinary currency. Explicit modifiers are the ones you craft — the prefixes and suffixes you see in the upper block of an item's tooltip. Fracturing, annulment, divine, chaos, exalted, regal — all operate on explicits.

Enchantments

Above the implicit sits a third, less-common layer: the enchantment. Enchantments are not prefixes or suffixes, do not count towards the 6-modifier limit, and are not produced by ordinary crafting currency. They arrive by specific routes — most often a Vaal Orb corruption outcome, or a socketable augment that grants one. Treat an enchantment as a bonus line you occasionally inherit rather than something you craft toward; the bulk of this codex concerns explicit modifiers.

Attribute Base Types — Why Two Bases of the Same Slot Differ

Before mod pools, tags, or breakpoints matter, the base type itself decides which modifiers are even eligible. PoE2's three attributes — Strength, Dexterity, Intelligence — each map to a defence and an attribute the base can carry, and a base draws only from the pools its attribute(s) permit. This is why two body armours of the same slot can have completely different mod pools.

• Pure Strength — provides Armour; can roll armour defence modifiers and Strength as its attribute. It cannot roll evasion or energy shield.
• Pure Dexterity — provides Evasion; rolls evasion modifiers and Dexterity.
• Pure Intelligence — provides Energy Shield; rolls energy shield modifiers and Intelligence.
• Hybrid bases (Str/Int, Str/Dex, Dex/Int) — draw from both contributing pools. A Strength/Intelligence body armour can roll armour and energy shield, and both Strength and Intelligence.

Weapons follow a softer version of the same rule. Attribute type does not gate damage the way it gates armour defences — a pure-Dexterity bow and a pure-Strength mace can both roll physical damage — but it does gate the attribute a weapon can carry, and ranged-vs-melee typing shifts other parts of the pool. The practical takeaway: a hybrid base trades a wider, more flexible mod pool for the cost and rarity of finding one, while a pure base gives a thinner, more predictable pool. Pick the base for the pool you actually need before worrying about its item level.

Modifier Groups

Every modifier belongs to a modifier group, and an item can carry only one modifier from a given group at a time. This is the mechanism behind a behaviour every crafter eventually meets: an Essence of the Body that grants maximum life will simply fail to apply to an item that already has a maximum-life modifier — the game reports that the item already has a modifier of that type, and consumes nothing. The group rule, not bad luck, is the cause.

The same rule cuts the other way as a deliberate tool. Because a group can hold only one occupant, placing a cheap, unwanted modifier from a group can block a more dangerous modifier in that same group from ever rolling there. This is advanced and situational, but it explains why experienced crafters sometimes appear to add "bad" mods on purpose. For everyday crafting the rule you need is the simple one: one modifier per group, and a guaranteed-mod currency will fail rather than duplicate.

IIItem Level & Tier Breakpoints

A breakpoint is the item level at which a higher tier of a given modifier becomes possible to roll. This is the foundation that informs every later choice in this codex — which base to keep, which essence to use, when to corrupt, when to stop. The concept does double duty: there are leveling breakpoints (gear refresh cadence during the campaign) and crafting breakpoints (mod-tier thresholds you target during endgame crafts). They use the same underlying mechanic, so they're treated together here.

Two Item-Level Numbers, Kept Separate

Every item carries an Item Level (ilvl), fixed when it drops, equal to the level of the area it came from. Every tier of every modifier carries an internal Mod Level (also called drop level). The rule is one line:

How to Read Tiers In-Game and Out

In-game, enable Advanced Mod Descriptions in UI Settings, then hold Alt over an item: the tier (T1, T2, …) and roll range appear in grey text next to each modifier. T1 is always the highest tier. What is not shown in-game is the modifier's tags (life, attack, elemental, minion, etc.) or the modifier's mod level — for those, you go to the database.

Two Kinds of Breakpoints

Important Crafting Breakpoints (Reference)

The table below summarises commonly cited mod-tier breakpoints. These are indicative values compiled from multiple community sources; the source-of-truth for any specific craft is PoE2DB's per-base modifier page.

Leveling Breakpoints — Caster +Level Skills

The endgame table above captures ceilings — what's possible on an ilvl 80+ base. During the campaign, casters care about a different cadence: the character-level thresholds at which a stronger +# to Level of [type] Skills tier becomes purchasable from vendors or rollable on dropped bases. Unlike martial weapons (where the base type itself upgrades in a steep curve — wrapped quarterstaff → long quarterstaff → next tier — and the mods follow), caster weapons gain power primarily through these +level rolls. Knowing the cadence tells you when to stop hovering items between thresholds and when to start aggressively shopping.

The Strategic Tradeoff: High ilvl vs Narrow Pool

The naive instinct is to always craft on the highest-ilvl base possible. That maximises the ceiling, but it also widens the pool of mods that can roll — every lower tier of every mod is still eligible. A deliberately lower-ilvl base excludes the top tiers entirely but also excludes a great many other competing mods, making each slam much more likely to land what you want.

The community heuristic for budget movement-speed boot crafting illustrates this: an ilvl 82 base is needed for 35% movement speed and T1 resistances, but ilvl 82 two-socket bases are rare and expensive. A base in the ilvl 75–80 range gives access to most desirable rolls with a much thinner pool — often a better expected-value craft. The exception is when you're going for a true endgame mirror-tier item, where the ceiling matters and the cost of additional slams is acceptable.

Where Breakpoints Resurface in This Codex

Every later section assumes you know which breakpoint you're aiming for. Specifically:

• Currency Tiers (§III) — Greater Exalts require ilvl ≥ 35, Perfect Exalts require ilvl ≥ 50. These are currency-side ilvl gates that interact with the mod-side gates above.
• Essences (§V) — the essence forces its guaranteed modifier, but the tier of that modifier is still bounded by your base's ilvl. A Perfect Essence on an ilvl 70 base will roll the highest tier available at ilvl 70, not the absolute top tier.
• Desecration / Abyss (§VIII) — Ancient bones require mod level ≥ 40; Preserved bones work at any ilvl; Gnawed bones cap at mod level 64. These are bone-side gates that stack with your base's ilvl gate.
• Quality & Catalysts (§X) — catalysts amplify whichever mods carry their tag, regardless of tier — but they amplify a T1 mod much more than a T6 mod, so the base ilvl gating the tier still dominates the outcome.

IIICurrency Tiers — Lesser · Greater · Perfect

Five of the basic crafting currencies exist in three tiers. Higher-tier orbs do the same action, but enforce a minimum modifier level, cutting the lowest-tier garbage results from the random pool. This is the single biggest determinism win available to the league-start crafter.

The five tiered orbs are: Orb of Transmutation, Orb of Augmentation, Regal Orb, Chaos Orb, and Exalted Orb. Each exists as Normal / Greater / Perfect.

Perfect Tier — Two Floors, Not One

The Perfect tier does not share a universal modifier-level floor. The currencies split into two groups:

The difference is practical, not cosmetic. Perfect Transmute and Augment (floor 70) sit at the start of a craft chain and aggressively narrow the affix pool — they are fishing tools for top-end affixes. Perfect Exalt, Regal, and Chaos (floor 50) sit later in the process and need a broader viable pool, so their floor is lower. Reducing all of these to a flat "50" loses behaviour that materially affects crafting decisions.

IVThe Currency Index

The complete crafting orb stack, in the order you typically encounter them. Each entry covers what the orb does, what state of item it acts on, and the strategic note worth keeping in mind.

Rarity-Changing Orbs

Modifier-Manipulating Orbs

Shards & Fragments

Most basic orbs have shards that combine 1-for-X into the full orb (Transmutation Shards, Regal Shards, Chaos Shards, etc.). You acquire shards from salvage and vendor recipes — they aggregate into orbs over time without you needing to think about them. The Currency Exchange tab handles conversions automatically.

VEssences

Essences guarantee a specific modifier when used. They come in four tiers: Lesser, Greater, Grand (sometimes called Normal), and Perfect.

Essence Catalogue

The named essences and the modifier each guarantees, grouped by what they do. The exact magnitudes vary by tier and item type; the table below is the kind of effect.

Premium / Endgame Essences

A handful of essences add notable-passive-like modifiers or roll on specific slots only:

• Essence of Delirium — adds a notable-passive style modifier to body armour. Run-defining when it lands well.
• Essence of Hysteria — used on Foci for energy shield recharge rate. 0.5: ES recharge rate value on Foci is now 20–23% (previously 41–45%).
• Essence of Horror — gloves / boots; can roll "100% increased Effect of Socketed Gems", a top-end damage roll for socketed setups.
• Essence of Insanity — corrupted-essence variant; behaves like a Vaal Orb but with paired corrupted mods. Trial of Chaos drop.
• Essence of the Abyss — added with Abyss league. Removes one mod from a Rare and imprints a Mark of the Abyss meta-mod that gets replaced by a Desecrated modifier when next desecrated. See §VIII.

VIOmens

Omens are meta-modifiers. You activate one by right-clicking it in your inventory; the next time you use the relevant currency, the omen alters its behaviour. Only one omen of a given kind applies per craft, but you can stack different kinds — e.g. Greater Exaltation and Dextral Exaltation on the same Exalted Orb. They are consumed on the next applicable craft.

Side-Targeting Omens

The bread-and-butter omens. Every endgame craft uses these. They tell a currency to only hit prefixes (Sinistral) or only suffixes (Dextral).

Quantity-Modifying Omens

Mod-Pool-Modifying Omens — The Heavy Hitters

Abyss-Specific Omens

VIIThe Tag System

Every modifier in the game carries one or more tags. Tags are how PoE2 categorises mods, and many powerful deterministic crafts work by exploiting which mods do or don't share a tag. How central tag-based crafting is in practice depends on which tag-manipulating currencies are live in the current patch — treat it as a strong tool to reach for when those are available, and confirm against the patch you're playing rather than assuming it dominates every craft.

Common Tags You'll See

Tags are not shown on items in-game. This is a known UX gap: Alt-hover reveals the tier and roll range but not the tag list. To see a modifier's tags you go to PoE2DB and look up the modifier on the relevant base-type page — the tags appear as small bracketed labels next to each line. Mods often carry multiple tags: e.g. "+# to Level of all Minion Skill Gems" on a sceptre carries both the minion tag and the gem tag, allowing it to be targeted by either.

The Core Move: Tag-Anchored Crafting

Tags matter because two currencies in the live patch read them: Omen of Catalysing Exaltation (the jewellery tag-bias tool — see §VI) and tag-aware essence selection. The general principle is the same in both cases: get a modifier carrying a useful tag onto the item first, then let a tag-reading currency lean the next outcome toward mods sharing it.

This works because most modifier pools are large (50+ mods) while most tag pools are tiny (3–8 mods). Biasing a slam toward a narrow tag pool is far stronger than slamming blind — even when the bias isn't fully deterministic.

The same logic applies to essences: choosing an essence whose guaranteed modifier carries the tag family your build needs anchors the item before any later slam. The pattern is: get the right tag onto the item early, then use the tag-reading currency that fits the slot.

When to NOT Use Tags

Tag-based crafting fails when the relevant tag pool is large or contaminated. Damage is too broad a tag to be useful for tag-biased crafting on most items. Elemental is similarly broad. If a tag has 15+ mods that share it, you are not really being deterministic — you're just biased.

VIIIDesecration / Abyss — The Well of Souls

Added in patch 0.3.0 (Rise of the Abyssal). Lets you pick a modifier from three offered options, including exclusive Lich-pool modifiers unavailable through ordinary crafting.

The Mechanic

1. Acquire an Abyssal Bone from Abyss content (Abyssal Troves dropping after sealing a fissure, Abyssal Depths, the Dark Domain, or trade).
2. Apply the bone to a Rare item of the matching class. A green glyph (Desecrated modifier) is added. If the item already has 6 mods, a random mod is removed first.
3. Travel to the Well of Souls in Act 2 (through the Lightless Passage off Mastodon Badlands — has its own waypoint after first visit).
4. Insert the item. Three modifier options appear. Pick one. The item is no longer desecrated; the chosen modifier is permanent.

Abyssal Bones — The Matrix

Bones split on two axes: body part (what they desecrate) and quality (what ilvl restrictions apply).

Lich Modifiers — The Exclusive Pool

Desecration is the only way to obtain modifiers from the three Lich families. Each lich's mods are powerful, build-defining, and unavailable through any other crafting path:

• Kurgal — forced via Omen of the Blackblooded.
• Amanamu — forced via Omen of the Liege.
• Ulaman — forced via Omen of the Sovereign.

Each lich's pool is large — roughly 60–70 modifiers — and spans many archetypes rather than a single theme; all three mix damage, defence, ailment, minion, and utility mods. Do not rely on a one-word characterisation of a lich. The standard discovery flow is to check PoE2DB's Desecrated Modifiers list for the item class you're crafting, identify which lich carries the mod you want, and stack the appropriate Blackblooded / Liege / Sovereign omen on top of your side-targeting omen before applying the bone.

The Standard Desecration Flow

1. Item is Rare with 4–5 mods (an open slot on the side you want).
2. Activate Omen of Sinistral Necromancy (or Dextral) to force the side.
3. If you want a specific Lich's mod, also activate the Lich omen.
4. Apply the Bone. Item now has a hidden Desecrated mod.
5. If you want a second chance at the three options, activate Omen of Abyssal Echoes.
6. Travel to Well of Souls. Reveal. Pick from up to 6 mods (3 + 3 rerolled).

Failed Desecrate? Use Omen of Light

If the reveal gave you nothing usable, you have an unwanted Desecrated mod on the item. Omen of Light + an Orb of Annulment removes only the desecrated mod. Then apply a new bone and try again. This is the chase loop — most endgame desecration crafts involve 3–8 cycles.

IXFracturing Orbs

A Fracturing Orb permanently locks one random explicit modifier on a Rare item with 4 or more modifiers. The locked mod cannot be changed by Chaos, Annulment, Divine, or Vaal Orbs.

You acquire Fracturing Orbs primarily from Cleansed Maps (the cleansed-Corrupted-Nexus variant introduced in 0.2.0) and from the Currency Exchange. 0.5: Fracturing Orbs now require Atlas-passive specialisation to drop — they're grouped with Exceptional Items and the Basic / Overseer precursor tablets under the new specialisation system.

The Constraint

The locked mod is chosen at random. You have no control over which one fractures. On a 4-mod item, that's a 25% chance the locking lands on the mod you wanted. On a 5-mod item, 20%. Never fracture an item where most of the mods are unacceptable — you'll lock the wrong one.

The Isolation Principle — Why Fracture Is So Powerful

The real power of fracturing is not the lock itself — it's that the locked mod cannot be selected by an Annulment Orb. Pair that with a side-targeting Annulment omen and you achieve isolation:

Most mirror-tier crafts use this principle repeatedly to scrub away unwanted mods while keeping the good ones safe.

When to Fracture

• Yes — item has one exceptional mod and 3 acceptable-to-good mods. Worst-case (fracture lands on a non-target), the item is still usable.
• Yes — preparing a base for an isolation chain (you have many Annulment omens lined up).
• No — item has one good mod and 3 garbage. 75% you fracture garbage and turn a salvageable item into wreckage.
• No — mid-progression. Fracture Orbs are 9+ exalts each; do not burn them until the item is otherwise a clear win.

XQuality & Catalysts

Quality is a multiplicative bonus applied to an item's modifiers. It does not add mods; it makes the existing mods stronger by a percentage. Different item types use different quality currencies.

Catalysts — Quality for Jewellery

Catalysts are jewellery-specific quality currency. Unlike whetstones (which uniformly boost all stats), each catalyst type only boosts modifiers matching a specific tag. Applying a new catalyst replaces any existing catalyst quality on the item — they don't stack across types.

Breach Rings — The 50% Cap Exception

Standard rings and amulets cap at 20% catalyst quality. Breach Rings (the unique base type that drops from Breach) cap at 50%, making them by far the strongest jewellery base in the game when correctly catalysed. Save the rarer catalysts (Sibilant, Skittering, Xoph's) for Breach Ring finishers — the 50% multiplier is where you get your value.

XISockets · Runes · Soul Cores · Talismans

Sockets in PoE2 hold Runes, Soul Cores, or Talismans — three different families of socketable items. They are mechanically distinct from skill / support gems (which have their own dedicated gem sockets in the gem panel).

Adding Sockets

Artificer's Orbs add a socket to an item that has fewer than its maximum. Acquired by salvaging socketed items (10 Artificer's Shards = 1 Orb) or as drops. A second socket on a body armour or 2H weapon is added with a second Artificer's. Vaal Orbs can sometimes add sockets beyond the natural maximum (along with a corruption).

Once a Rune / Soul Core / Talisman is placed in a socket, it is permanent — you cannot retrieve it. You can overwrite it by placing a new socketable, destroying the old one. Plan socket choices late, after the item is otherwise finished.

Runes — The Reliable Workhorse

Runes drop from monsters in three rarity tiers: Lesser → Normal → Greater. Three Lessers consolidate into one Normal at the vendor; three Normals into one Greater (introduced in 0.2.0).

Soul Cores — Trial of Chaos Drops

Soul Cores are only obtained from the Trial of Chaos (Vaal Ultimatum-style rooms). They carry effects unobtainable on Runes. Examples:

• Soul Core of Azcapa — Weapons: attacks penetrate 15% Elemental Resistance · Armour: 15% increased Ailment Threshold.
• Soul Core of Zalatl — Weapons: +15 Spirit · Armour: 10% increased Rarity of Items found.
• Soul Core of Tzamoto — Weapons: +12% Crit Damage Bonus · Armour: hits against you have 10% reduced Crit Damage Bonus.
• Soul Core of Puhuarte — Ignite-related buildup.

Rounds 4, 7, and 10 of the Trial each guarantee one Soul Core. The 10-round variant is the most efficient farm.

Talismans — Azmerian-Wisp Sockets

Added with the Druid league (0.4 The Last of the Druids). Drop from Azmerian Wisp challenges. Each Talisman provides stats for one specific gear slot only, so they require slot-aware planning. Mechanically socketed the same as Runes and Soul Cores.

XIICorruption — Vaal Orbs & Atziri's Temple

A Vaal Orb applies one of several random outcomes to the item and renders it Corrupted — no further modification is possible. Vaal is always the last step.

Vaal Orb Outcomes

• Cosmetic / "nothing" — colour change only.
• Implicit added — a corrupted implicit appears (e.g. +1 to gem level on a wand, +1 to a particular skill on an amulet).
• Socket added — sockets can exceed natural maximums via corruption (a body armour can gain extra sockets this way).
• Modifier change — affix rerolling occurs. 0.5: the value-randomisation outcome (and Sanctifying) now multiply each modifier value based on its current value, rather than randomising it within a fresh range.
• Rare → Magic (rare items only) — can become Magic with similar mod values. Sometimes useful for body armour where the Magic state allows wider implicit-style mods, usually a brick.

On unique items, Vaal can add powerful corrupted implicits (often +1 to specific gem level) or brick the item by rolling it into a different rare. Never Vaal a build-defining unique without a backup.

Atziri's Temple & Vaal Infusers

Atziri's Temple — the Vaal endgame content, part of Fate of the Vaal now moved to core in 0.5 and reached through the city of Lira Vaal on the Atlas — is where Vaal Infusers are used. In 0.5 the single "Vaal Infuser" was split into four type-specific Infusers:

• Vaal Armourer's Infuser — applied to Armour. Existing pre-0.5 Vaal Infusers became this type.
• Vaal Blacksmith's Infuser — applied to Martial Weapons.
• Vaal Arcanist's Infuser — applied to Wands, Staves, and Sceptres.
• Vaal Catalysing Infuser — applied to Jewellery.

All four require the item to be at 20% Quality or above to use, and apply a corruption with the usual risk. They are the route to top-end quality corruption on a finished piece. Note the slot mapping: the old generic Infuser now lives on as the Armourer's (armour) — martial weapons need the Blacksmith's Infuser, not the legacy one. Twin-corruption (Vaal twice) remains possible through specific temple mechanics.

Corrupting Omens

• Omen of Sanctification — eliminates negative outcomes entirely. Only positive (sockets, implicits, modifier improvements) can occur. Extraordinarily rare and expensive.

XIIIThe Adept's Tricks

Every section above describes a tool. This section describes how the tools combine — the moves that turn a 1-mod base into a 6-mod finished piece without bricking. Each trick is named for easy recall; each cites the omens or currencies that drive it.

XIVMaster Workflow

The canonical order in which to apply everything, from a fresh base to a finished, corrupted piece. The order is governed by a single principle: cheap and reversible operations first, expensive and irreversible operations last.

1. Acquire a baseBuy or find an ilvl 81–82 base of the class you want. Verify the implicit suits the build. Verify with PoE2DB which mods can roll on this base before committing. Item level gates which modifier tiers can ever roll. A T1 mod that requires ilvl 82 cannot appear on an ilvl 78 base — no amount of currency fixes that.
2. Essence to Rare (with tag awareness)Use a Greater Essence targeting a modifier the build needs, and prefer one whose tags align with the rest of the item — especially on jewellery, where the next step can read those tags. This is the most-skipped step — most crafters just essence whatever feels strong. Think about tags first. The essence both guarantees a useful mod and anchors a tag. On jewellery, the right tag here makes the later Catalysing Exaltation slam far stronger. Wrong essence → wrong tag pool → weaker downstream bias.
3. Establish a tag anchor (jewellery)For rings and amulets, make sure the item carries at least one mod in the tag family you want before the catalyst step. If the essence didn't supply it, an alt-aug cycle on the magic state can introduce one. For weapons and armour this step is optional — there is no in-league tag-locked exalt, so a clean essence-anchored base is enough. Catalysing Exaltation reads the catalyst tag, and catalysts amplify mods already carrying that tag. An on-tag anchor turns the catalyst-then-exalt sequence into a real bias rather than an open slam.
4. Exalt slams to fill the open modsSlam Greater (cheaper) or Perfect (final-tier guarantee) Exalts to fill empty prefix/suffix slots. Use Sinistral/Dextral Exaltation to target which side the mod lands on. On jewellery, apply catalysts first, then slam under Omen of Catalysing Exaltation for a tag-biased result. This is the main slot-filling move. Side-targeting omens keep slams from overfilling a side; on jewellery the catalyst bias narrows the pool toward what you want.
5. Desecrate for the exclusive modIf a Lich modifier helps the build (chaos res, penetration, spirit), apply a Preserved or Ancient Bone (with Sinistral/Dextral Necromancy omen). Reveal with Abyssal Echoes active. Use Light + Annul to retry if needed. Lich modifiers are unavailable through ordinary crafting and often build-defining. Desecrate-loop until landed; the cost-per-attempt is modest.
6. Clean up with targeted annul or chaosItem now has 5 mods, possibly with one underperforming. Use side-targeted Annulment or Erasure omens to remove the weak link. If you have an Omen of Whittling and the weak mod is the lowest-level, that's even cleaner. The annul reopens a slot for one final premium slam. Doing it before fracturing keeps options open; doing it after fracturing risks locking the wrong mod.
7. Fracture (optional, high-end only)If the item now has 4+ excellent mods and you intend to push toward a 6-mod perfect roll, fracture. Pray the fracture lands on a high-value mod. If it does, proceed; if not, evaluate whether the fracture-on-this-mod is still acceptable. Fracture is the gateway to the isolation trick (Trick I) and to safely-corrupting an item without losing the most valuable mod. Skip on items below mirror tier.
8. Final slams — Perfect Exalt / Perfect EssenceOpen slots get filled with Perfect-tier currency under appropriate omens. Crystallisation omens if replacing a filler with a Perfect Essence. Sinistral/Dextral Exaltation if just adding a missing-side mod. Perfect tiers cost a lot but lift the modifier-tier floor. Doing this last means you only spend Perfect-currency once the item is otherwise final.
9. Apply quality / catalysts20% Whetstone / Scrap on weapons / armour. Targeted catalysts on jewellery (50% on Breach Rings). Apply before divining, so you're divining the post-quality numbers. Quality is a flat multiplier on existing mod magnitudes. Cheap. No downside. Easy to forget — many otherwise-good items go to market un-quality'd.
10. Divine for value rollsRepeated Divine Orbs reroll the numeric values of all mods within their ranges. Stop when the rolls are good enough — never chase further than you can afford to repeat. Numeric optimisation. Single-digit-percent gains. Do it only on items you're keeping.
11. Sockets and runes / soul coresUse Artificer's Orbs to add sockets to maximum. Insert your chosen Rune, Soul Core, or Talisman. Once placed, the socket is filled forever (overwriting destroys the contents). Sockets cannot be added after corruption (except via Vaal). Doing this now keeps the corruption-step door open for a socket-adding implicit.
12. Corrupt — last, and only when finishedVaal Orb. The item is locked from all further modification, but gains a corrupted implicit, an extra socket, or another effect (or rerolls — be ready to brick). Omen of Sanctification removes negative outcomes entirely (at extreme cost). Corruption is irreversible. Every prior step's flexibility is consumed here. Doing it before any prior step is over throws away every later constraint.

XVPatch 0.5 — Runes of Aldur Additions

Ezomyte Remnants & the Runebook

Throughout the campaign and endgame, you encounter Ezomyte Remnants — stone monuments with pre-inscribed runes and empty slots. The campaign NPC Farrow teaches you to inscribe additional runes to complete recipes. Each completed recipe is permanently recorded in your Runebook, available at any future Remnant.

Inscribing runes resurrects nearby corpses as undead, empowered with modifiers matching the runes used (a fire rune empowers the wave with fire, an oath rune nominates an invincible leader, and so on). Defeat the wave; the inscribed item appears at the Remnant.

Larger Remnants in higher-level areas have more rune slots — up to 6, 7, or 8 — yielding rarer crafting currencies but also stacking more monster empowerment.

The richest Remnant interaction is on the Inland Heath ocean island (see the Endgame Guide): a gigantic master Remnant is ringed by smaller runestones, and each runestone you detonate activates another slot on the master — fully cleared, it opens up almost any recipe in a single encounter. It's the most efficient place to chase specific Runebook recipes once you reach the endgame ocean.

Verisium & Runic Ward

Verisium is the new core resource of the 0.5 league. It drops from Remnants, Expedition encounters, and ocean exploration. It powers:

• Runic Ward — a new defensive layer that activates when life drops to zero. Acts as an additional health pool that sustains the character for a short window. Crafted onto any armour piece (uniques included) via the Verisium Anvil, unlocked after an early-game vault encounter.
• Kalguuran skills — new active abilities that spend Runic Ward instead of mana. Class-agnostic, weapon-agnostic. Examples: Triskelion Cascade (triggers next spell in a triskelion pattern), Frostflame Nova (converts ignites to frost-fire), Hollow Shell (ally guard), Mark of Repulsion (push-away curse).

Runeforging — Upgrading Uniques

At the Mystic Refuge in Act 3, Farrow learns to Runeforge unique weapons. Many low-level uniques can be upgraded with Verisium to do significantly more damage, bringing them into endgame viability. A subset of Kalguuran uniques (e.g. the new Serle's Grit) have multiple possible Runeforge outcomes — gamble-style upgrades with build-defining effects.

Runic Alloys — New Mod Pools

A new currency class. Alloys add modifiers not normally craftable to items. Verisium combined with other materials produces different alloy types:

• Imbued Alloy — ailment damage modifiers
• Expansive Alloy — area of effect modifiers
• Mystic Alloy — caster-pool modifiers
• Swift Alloy — speed-pool modifiers
• Runic Alloy — broader Aldur-themed mods

A subset of Runes are meta-crafting runes: applied to a socket, they unlock a new mod pool on the item that subsequent ordinary orb crafting can roll. The reveal demonstrated a Rune of Chronomancy on boots that unlocked time-related mods (cooldown speed, skill effect duration).

Elemental Conversion Runes

Specific Runes can convert all existing elemental damage modifiers on a non-unique weapon from one element to another. Used to consolidate three elemental damage rolls into one element — turning a multi-element weapon into a single-element powerhouse.

Jewel Socket Conversion

A Rune that destroys the rune sockets on an item to convert them into a Jewel socket. Applies to items with existing rune sockets — converts socket count into a jewel slot.

The Full Runes of Aldur Family — confirmed list

The 0.5 patch notes confirm a substantial Runes of Aldur crafting suite. Acquisition: most are unlocked through Farrow's four campaign quests (Act 1, 2, 3, 4) and crafted at Remnant encounters; Verisium is the underlying currency, mined from monsters raised by Remnants.

• Verisium Runeforging (Act 1 unlock) — spends Verisium to add Runic Ward to armour. Below item level 55: no downside. Above 55: trades some regular defences for Runic Ward.
• 13 Runic Alloy currencies (Act 2 unlock) — add new crafted modifiers by replacing an existing modifier (mechanically similar to Perfect Essences). Crafted via Remnants.
• Unique Verisium Runeforging (Act 3 unlock) — upgrades the base type of Unique weapons / armours that drop below level 55 into endgame-viable bases (higher damage / defences + Runic Ward). Unique armours above 55 can be Runeforged to swap defences for Runic Ward. Kalguuran uniques (e.g. Serle's Grit) can take extra properties.
• 13 Ancient Runes (Act 4 unlock) — powerful weapon-type-specific runes, crafted via Remnants.
• 13 Mythical runes — early-game runes with significant boosts, intended for level 15+ characters.
• 3 Fluxes — transform the resistances on an item from one element to another.
• 15 Meta crafting runes.
• 60+ runes created by destroying a Unique — the rune gains some of the destroyed unique's properties.
• 15+ Runic Ward runes — add or modify Runic-Ward-related properties.

Remnants also craft 21 Kalguuran skills and 8 Kalguuran supports — these are skill/support gems, out of scope for this crafting reference; the mechanic is noted here for completeness only.

Genesis Tree — Breach Crafting Overhaul

The Breach league rework introduces the Genesis Tree inside the Keepers of the Flame monastery. After stabilising Breaches into a new phase and defeating Marshals of Xesht to drop Hive Blood and Wombgifts, you bring them to the tree:

• Wombgifts are placed into the tree and fertilised with Hive Blood, birthing a specific class of jewellery (amulets, rings, belts).
• The tree has 15 allocatable nodes, free-to-respec at any time, controlling: base type selection, modifier pool, tier floors, guaranteed mods, and new base types unavailable elsewhere (e.g. an amulet with a spirit skill built in, or one with a rune socket).
• Specific tree branches add entire new mod classes: a caster mod set for rings (spell damage, seal generation for Unleash), a minion mod set for rings, a new amulet mod pool for ailments.
• Additional branches handle belts and currency crafting, including new Catalyst variants for jewels.

Liquid Emotions — Delirium Jewel Crafting

The Delirium rework expands the use of liquid emotions. Beyond their existing role (instilling amulets with notable passives), emotions can now add crafted modifiers to jewels:

• Liquid Despair → critical hit chance on jewels
• Liquid Suffering → movement speed or area of effect on jewels
• Potent Liquid Melancholy → on-hit effect mods (only from human map bosses)
• Potent Liquid Paranoia → effects unavailable elsewhere
• Concentrated Liquid Isolation → late-game variants

Some emotions drop only from specific delirium-affected boss types, making strategic Atlas planning a precondition for some jewel crafts. Time Lost Jewel crafting also expands via specific simulacrum encounters.

Ritual — Unique-or-Omen Rewards

Rituals no longer offer junk rewards. Every item in the Ritual reward window is now a Unique or an Omen. Crafters who farmed Rituals primarily for Omens see a major efficiency lift. New Omens may appear; verify the omen list post-launch.

Atlas Master Crafting Effects

The new Masters of the Atlas (Jado, Hilda, and others) include nodes affecting map currency and corruption outcomes — for example, "corrupted Waystones gain an additional modifier (but send you to an unknown location)". These don't change the crafting bench, but they alter the rate at which you acquire crafting-relevant materials.

XVITools & Resources

A short list of external references this codex draws on. There are many other excellent community resources for PoE2 — the omissions here aren't editorial judgements, just an attempt to keep the list short.

• poe2db.tw — datamined database. Every base, every modifier, every tier, every tag, every ilvl gate, every weight.
• craftofexile.com — calculator and emulator. Test a craft sequence before spending currency on it.
• maxroll.gg/poe2 — guide site.
• mobalytics.gg/poe-2 — guide site.
• vulkk.com — guide site.
• poe.ninja/poe2 — currency price tracking. The in-game Currency Exchange (talk to Alva in your hideout) is the live trading interface.

Reading a Modifier on PoE2DB

The typical line looks like: "#% increased Maximum Life [life · defence] Tier 1 · ilvl 81 · weight 600". The bracketed terms are the tags. The Tier and ilvl gate when it can roll. The weight is the relative probability of that specific mod among all mods that could possibly roll at that point in the craft. Heavier weight = more likely. Some elite-tier mods carry very low weights (e.g. weight 100 vs the standard 600–1000), and those are the ones that tag-based exalt manipulation — Catalysing Exaltation and tag-aware essence choice — is designed to fish out.

XVIICaveats & Sources

Known Areas of Uncertainty

• Omen of Catalysing Exaltation magnitude — the bias toward the catalyst tag is real but the exact percentage shift is not documented in-game; community testing suggests it is meaningful but not deterministic.
• Patch 0.5 Runic Alloy mod pools — Imbued / Expansive / Mystic / Swift names and effects are from the reveal stream; the full list of new modifiers each unlocks is not yet public.
• Genesis Tree node count — the reveal showed 15 allocatable nodes, but the exact branches and their gating may shift in the patch notes.
• Soul Core list — only a subset of named Soul Cores are reliably documented externally; the full list is in-game and on PoE2DB once you encounter them.
• Specific mod-tier ilvl gates — the breakpoint table in §II is compiled from community sources and is illustrative. The source-of-truth for any specific base is PoE2DB's per-base modifier page.

What Changes Between Patches

• Omen list — new omens have been added across 0.2, 0.3, and 0.4. The Omen of Homogenising Exaltation and Omen of Homogenising Coronation had their drops disabled in 0.4 (existing copies stay functional); Crystallisation omens were retuned in 0.3.
• Essence list — Essence of the Abyss and several others were added in 0.3.0. Perfect Essence of Sorcery can no longer be used on Focus (0.4 change).
• Drop rates & costs — these shift every patch and every week of a league. Currency Exchange prices are the live source-of-truth, not codex values.

Patch 0.5 Status

The 0.5.0 patch notes are released (21 May 2026). §XV has been reconciled against them; confirmed contradictions elsewhere in the codex (catalyst acquisition, Greater currency rarity, essence value changes, the value-randomisation corruption outcome) are folded in. Cross-check PoE2DB and in-game tooltips before any expensive craft — datamining lags real in-game behaviour by hours-to-days, and the codex follows live-game truth, not the other way around.

Removed, disabled & unobtainable in-league — for the record

• Omen of Homogenising Exaltation — the tag-locked Exalt that older guides treat as the core deterministic move for "+# to Level of all X Skills" crafts. Its drops were disabled back in 0.4, so it is not obtainable in the Runes of Aldur league; legacy copies remain functional and tradeable only in Standard. Tag-locked level-of-skill crafting is therefore a Standard-only technique — in league, the live tag tools are Catalysing Exaltation and tag-aware essences (see §VI, §VII). This omen and its uses have been removed from the crafting body of this codex for that reason. Mentioned here so the technique isn't forgotten if drops are ever re-enabled.
• Recombinators (formerly §IX) — the Expedition-fuelled bench that combined two items of the same class into a single output with a chosen mod subset. Disabled for the duration of The Runes of Aldur league alongside the rest of Expedition; expected to return when Expedition reintegrates into Standard. The deterministic two-mod-starter trick that lived in §XIII Tricks (formerly Trick III) and the recombinate-for-fractured-tag option in the §XIV workflow both relied on it — they're removed from this codex while the bench is offline. Mentioned here so the mechanic isn't forgotten when it comes back.
• Omen of Recombination — paired with the Recombinator (rolled success chance twice, took the better outcome). Removed in 0.5; existing copies deleted on login.
• Omen of Corruption — could no longer be obtained as of 0.5 (the patch notes removed it from the drop / vendor pool). All references stripped from this codex.

A Last Word

PoE2 crafting is a system of narrowing constraints. The cheapest crafts you'll do use one constraint at a time; the most expensive use eight stacked. The most-asked-for thing in this game's crafting Discord is "what's the deterministic version of this craft?" — and the answer is almost always "stack one more omen on top of what you're already doing." That's the whole game, and once you see it the rest is just remembering which omens exist.
