Crafting Resources


Creating or improving items through adding, removing, swapping or altering modifiers in Path of Exile is referred to as Crafting. The Crafting system is so expansive that many pursue it as a separate endgame to specialize in. This article covers the various Crafting options and how they can help with your own projects.

Most of Path of Exile's in game currency is used to both craft and trade for items. There are many methods to crafting, including: Orbs and other currencies, Vendor Recipes, the Crafting Bench, Delve Fossils and the Betrayal mechanic. While crafting outcomes are usually unpredictable, there are set ways to guarantee certain items. For inexperienced crafters it's often easier and cheaper to purchase an item from trade rather than crafting it yourself. Do not start an advanced crafting project before diligently researching how to maximize the odds of getting the desired result and ensuring the correct crafting base / item level can roll the desired tier of modifiers on the item. A simple, negligent mistake can prove extremely costly and potentially ruin an entire item!

Successfully completed high-end crafts are highly valuable and expensive to purchase. Under some circumstances (such as for non-meta builds or when trying to create the perfect item for your build) an item with the desired mods may not exist yet. This means the only way to obtain it is through crafting. At the high-end, especially in niche item markets, many players are willing to pay more than the crafting amount invested to acquire what they need, making crafting a profitable endeavor.

Some items are extremely difficult to make and can cost more than a Mirror of Kalandra, allowing owners of such prestigious items to set up a so-called "Mirror Service" to create an unmodifiable copy of said item at a fee. Hint: Whenever you see a godly item listed on the trade site for the price of 1 Mirror, that means the owner is open to be contacted for Mirror Service. It's not the actual price of the item. Nonetheless, Crafting is important at all steps of your character's journey. Even if you don't intend to craft Mirror-worthy items yourself, you need to know the basics in order to understand the value of items. Let's jump in!

Basic Crafting Currencies

Basic currencies can modify items of varying rarities. Magic items can only roll up to two random modifiers, while rare items can roll up to six (exceptions exist, e.g. Jewels can usually only have 4). There are many different types of currencies to choose from. These currencies' intrinsic values are directly linked to their usefulness.

  • Orb of Transmutations upgrade a normal item into a magic item with one to two random modifiers.
  • Orb of Alterations reforge a magic item with 1-2 new random modifiers.
  • Orb of Augmentations add a new random modifier to a magic item.
  • Orb of Chances upgrade a normal item into either magic, rare or unique quality. The resulting rarity is chosen randomly, however higher rarities are much less likely to upgrade into and unique items have varying odds depending on their rarity.
  • Orb of Alchemys upgrade a normal item into a rare with 3-6 random modifiers.
  • Orb of Scourings remove all modifiers from an item reverting the item to its normal rarity.
  • Regal Orbs upgrade a magic item to a rare item and augments (adds) one additional random modifier.
  • Chaos Orbs reforge a rare item with 3 to 6 new random modifiers. Note: since this orb has other uses and sinks such as the Map Device, it may be cheaper to use an Orb of Scouring and an Orb of Alchemy to achieve the same result as a Chaos Orb.
  • Orb of Annulments remove a random modifier from an item.
  • Exalted Orbs augment a rare item with a new random modifier.
  • Veiled Chaos Orbs reforge a rare item with new random modifiers, including a Veiled modifier. Can only be used on items that can have a Veiled modifier.

Base Modifying Currencies

  • Blacksmith's Whetstones improve the quality of a weapon.
  • Armourer's Scraps improve the quality of an armour.
  • Chromatic Orbs reforge the colour of sockets on an item, but is more likely to roll colours native to the base's defence type (Green = Evasion, Red = Armour, Blue = Energy Shield).
  • Orb of Fusings reforges the links between sockets on an item. Items are more likely to fully fuse at higher quality.
  • Blessed Orbs randomizes the numeric values of an item's implicit modifiers.
  • Divine Orbs randomizes the numeric values of an item's modifiers.

Essences Currencies

Essences are part of a complex group of currency items used in crafting. Essences can be used to upgrade a normal rarity base to a rare with one guaranteed affix. Higher tier Essences can be used to reforge the affixes of rare equipment.

  • Deafening Essence of Anger
  • Deafening Essence of Anguish
  • Deafening Essence of Contempt
  • Deafening Essence of Doubt
  • Deafening Essence of Dread
  • Deafening Essence of Envy
  • Deafening Essence of Fear
  • Deafening Essence of Greed
  • Deafening Essence of Hatred
  • Deafening Essence of Loathing
  • Deafening Essence of Misery
  • Deafening Essence of Misery
  • Deafening Essence of Rage
  • Deafening Essence of Scorn
  • Deafening Essence of Sorrow
  • Deafening Essence of Spite
  • Deafening Essence of Spite
  • Deafening Essence of Suffering
  • Deafening Essence of Torment
  • Deafening Essence of Woe
  • Deafening Essence of Wrath
  • Deafening Essence of Zeal

Corrupted essences do not appear naturally on monsters trapped within Essence crystals, and can only be obtained by corrupting an Essence monster with a Remnant of Corruption.

  • Essence of Delirium
  • Essence of Horror
  • Essence of Hysteria
  • Essence of Insanity

Crafting Bench

The Crafting Bench found in your Hideout applies specific modifiers of varying tiers for a typically small price. Crafting recipes can be found throughout the acts as well as in maps. The Betrayal league mechanic grants veiled modifiers which can be learned by unveiling them with Jun in your Hideout. By default, items are limited to having only one crafted modifier, however with the "Can have up to 3 Crafted Modifiers" you can effectively double that (that mod itself also counts as one).

Bench crafting basic stats like Life and Resistances is inexpensive and can be done as soon as you acquire the recipes as you level through the acts. Adding these stats to items can be worthwhile to keep your Resistances capped and your Life Pool high.

Mod Groups

The existence of a modifier on an item prevents one of the same mod group from being added. This mechanic is extremely important for endgame crafting as it could prevent or increase the odds of augmenting the modifier you want. Craftable mods can be added to an item to temporarily block any affix of that mod group, removing it from the pool of possible modifiers. This is a very useful technique to increase the odds of augmenting a desired modifier through systems such as: Eldritch, Harvest and Meta crafting.


Tags are a way of identifying modifiers. They also allow for deterministic outcomes with the use of bench crafts such as Cannot roll Attack Modifiers "of Spellcraft" & Cannot roll Caster Modifiers "of Weaponcraft". Tags also allow you to target specific modifiers thanks to Harvest reforges and augments, as well as Fossils. If you wish to see what tags are present on any particular item, refer to its respective page on Craft of Exile.

Item Bases

Not all modifiers can roll on all item bases. There are a great variety of item bases which can roll different mods, with some being unique to that type of base. Make sure to refer to the PoEWiki before undertaking a crafting project to make sure you are using the best Helmet, Body Armour, Gloves, Belt, Ring, Amulet, Weapon and Shield bases. Additionally you can also visit Craft of Exile as it provides a list of all possible craftable modifiers on all item bases. Good bases are identified by their high base defense values. The inherent defensive values of an item have a variance of 20%. Sacred Orbs randomize the numeric values of the base defenses on an armour piece, allowing players to further optimize their character's defensive stats.

Fractured Bases

Fractured Items can drop randomly from certain League Mechanics such as Delve or appear in reward choices from Rituals. They are exactly like any other magic or rare item, but with one affix being completely locked in place. This Fractured mod can't be removed or changed in any way, not even from a Chaos Orb, Divine Orb or Vaal Orb (even bricking the item with a failed Corruption keeps the Fractured mod). These items can be identified by their light blue glow and the Synthesis influence icons next to the name. The Fractured mod itself is always at the top of the explicit affix list.

A Fractured Belt

Synthesised Bases

Synthesised Items are special bases that have new, typically unobtainable implicit modifiers (up to 3 at a time). The full list and their ranges are massive (check them for each base type here). They are not necessarily better than regular items - in fact, these implicits can be a direct downgrade from the standard ones on some bases. Synthesised Items have a distinct blue glow and cannot be upgraded into unique quality using an Orb of Chance because their new base types don't have any valid uniques.

There is no way to reliably target-farm a desired Synthesised base anymore. You have to rely on the law of large numbers and hope to hit the jackpot. The main sources of Synthesised Items are the Synthesised Maps (with the Atlas Passives allocated) and their corresponding Maven Invitations.

Make sure to check out the Synthesis League mechanics guide to learn more about the items it can offer!

Meta Crafting

Advanced crafting techniques revolve around the interaction of craftable Meta mods and basic currencies. Keep in mind that these techniques of crafting require multiple Exalted Orbs.

Cannot roll Attack Modifiers "of Spellcraft"

This craft blocks any Caster modifier from being augmented onto an item. It also ensures that modifiers with the "Caster" tag cannot be removed when using an Orb of Annulment. This can be extremely useful when trying to augment a random non-caster modifier on an item, or alternatively target removing a non-caster modifier from an item. Note: Harvest reforges, Fossils and the Chaos Orb do not respect this meta mod, i.e. the item will be reforged unpredictably.

Cannot roll Caster Modifiers "of Weaponcraft"

This craft blocks any attack modifier from being augmented onto an item. It also ensures that modifiers with the "Attack" tag cannot be removed when using an Orb of Annulment. This can be extremely useful when trying to augment a random non-attack modifier on an item, or alternatively target removing a non-attack modifier from an item. Note: Harvest reforges, fossils and the Chaos Orb do not respect this meta mod, i.e. the item will be reforged unpredictably.

Prefixes Cannot Be Changed "of Prefixes" & Suffixes Cannot Be Changed "Suffixed"

In the majority of advanced crafting projects, crafters focus on finishing either Prefixes or Suffixes first before moving on to complete the other. This is because it is much easier to focus on getting three useful affixes on an item before moving on to the final 2+ affixes. A typical scenario is crafters use the use the Prefixes/Suffixes Cannot Be Changed meta mod to protect either the prefixes or suffixes before reforging with Harvest to have increased odds at rolling the desired 4th modifier. Alternatively Prefixes/Suffixes Cannot Be Changed allow for an Orb of Scouring to remove undesirable modifiers from an item. Note: the crafted modifier will also be removed as the prefix craft is a suffix, and the suffix craft is a prefix. So it must be crafted again after every reforge attempt, or every time the crafter wishes to revert to the prefix/suffix base. This makes it an expensive crafting method!

Can have up to 3 Crafted Modifiers "of Crafting"

Allows for two additional crafted modifiers to be added to an item. This allows for mid tier items to be finished into 5 useful mod items at relatively low cost compared to their non bench crafted counterparts. This craft also has uses outside of finishing items such as when a crafter wishes to augment a 5th modifier on an item with the Aisling Betrayal craft.

Aisling T4 Betrayal Craft

When players strategically place Aisling in Research and upgrade her to level 3, once they run the Mastermind encounter they can remove one random modifier from an item while also augmenting a Veiled affix onto it. This Veiled affix varies depending on that item slot you applied the craft to. It is possible to block an undesired modifier from being unveiled by crafting a modifier of the same mod group on the item before unveiling. Therefore it is essential to first look at the possible outcomes when unveiling. The result is a more powerful version of a craftable veiled modifier. In some niche situations or for certain builds veiled modifiers can be best-in-slot, however most are not as good as the best possible modifier. They are, however, a cheaper and more accessible way to finish an item.

An alternative to T4 Aisling is the Veiled Chaos Orb in combination with the Prefixes or Suffixes Cannot Be Changed crafts to force a veiled modifier as your 4th modifier. This method, however, will not result in a best-in-slot 6 mod item, but can be a much cheaper method for getting a great 5 mod item.

Vorici White Sockets Betrayal Craft

When players strategically place Vorici in Research and upgrade him to level 3, once they run the Mastermind encounter they can modify an item to have 1-6 White Sockets. White sockets are colour agnostic, i.e. you can put any coloured gem in there!

Hillock Weapon, Armour and Flask Quality Betrayal Craft

When players strategically place Hillock in Transportation, Fortification and Research and upgrade him to level 3, once they run the Mastermind encounter they can modify an item to have a higher quality.

  • Transportation - Hillock improves the quality of a Weapon to 30%.
  • Fortification - Hillock improves the quality of an Armour to 30%.
  • Research - Hillock Improves the quality of a Flask to up to 28%.

The Meta-Crafting Meta

The current most common way of crafting 5+ modifier items outside of Eldritch crafting is throughthe aforementioned meta crafts and the Aisling level 4 Betrayal Craft. Combining the different methods described above is key to creating a great outcome. Projects should only be undertaken when you have sufficient spare currency as they easily go into the dozens of Exalts. Here's an example:

  1. Craft an item with Harvest, Fossils, or Essences or Awakener's Orb until it has three desired Prefixes or Suffixes.
  2. Use the bench to craft Prefixes Cannot Be Changed.
  3. Use a Harvest reforge to guarantee a mod with the appropriate tag; on some bases it can even guarantee a specific modifier to roll.
  4. Once your item has three desired Prefixes or Suffixes + one additional affix you wish to keep, craft Prefixes or Suffixes Cannot Be Changed and use a T4 Aisling for a 50% chance to retain your desired mod. Alternatively if you have 2 open suffixes you can craft Can have up to 3 Crafted Modifiers and Prefixes Cannot Be Changed for a 66% chance of success.
  5. Use the Crafting Bench to block a Veiled mod you least desire and unveil in hopes of getting a useful modifier.
  6. Repeat steps 4-5 until you have your desired mods.
  7. Finish the item with a bench crafted modifier.

Eldritch Crafting Currencies

Eldritch Crafting refers to the use of Eldritch Currencies. These currencies present a new immensely powerful way to improve conventional items. They add powerful Implicits and modify the prefixes or suffixes of an item depending on which influence is dominant. This method can be used on non-Conqueror influenced Body Armour, Boots, Gloves or Helmets. The Eldritch Crafting process can drastically cut the cost of a craft by replacing the need for Meta mods to lock Prefixes or Suffixes through it's dominance mechanic. Additionally adding implicits can be done relatively cheaply, making this crafting method the most cost effective method for gaining power. Follow these links to find a list of all Eater of Worlds & Searing Exarch modifiers.

  • Lesser Eldritch Embers, Greater Eldritch Embers, Grand Eldritch Embers & Exceptional Eldritch Embers add a Searing Exarch Implicit modifier to a Body Armour, Boots, Gloves or Helmet. This replaces any implicit modifier other than Eater of Worlds implicit modifiers.
  • Lesser Eldritch Ichors, Greater Eldritch Ichors, Grand Eldritch Ichors & Exceptional Eldritch Ichors add a Eater of Worlds Implicit modifier to a body armour, boots, gloves or helmet. This replaces any implicit modifier other than Searing Exarch implicit modifiers.
  • Eldritch Chaos Orbs rerolls prefix modifiers if the Searing Exarch is dominant. Rerolls suffix modifiers if the Eater of Worlds is dominant.
  • Eldritch Exalted Orbs add a prefix modifier if the Searing Exarch is dominant. Adds a suffix modifier if the Eater of Worlds is dominant.
  • Eldritch Orb of Annulments removes a prefix modifier if the Searing Exarch is dominant. Removes a suffix modifier if the Eater of Worlds is dominant.
  • Orb of Conflicts unpredictably raise the strength of one Searing Exarch or Eater of Worlds modifier on an item and lowers the strength of another. Lesser modifiers that have their strength lowered are removed. The chance of raising or lowering a modifier depends on its relative strength, i.e. a lower tier implicit modifier is more likely to be upgraded over a higher tier one.

Eldritch Implicits

The new Eldritch Implicits allow for Eldritch modifiers to be applied to already good items that you may have found or bought. This gives another avenue for creating useful items for your build. These currency items, as well as items with already present Implicits, start dropping consistently in Tier 14+ Maps. This allows you to gain a substantial power spike before taking on Tier 16 Maps and bosses. Eldritch Implicits replace existing Implicit mods on items which have one already present, and allow for two Implicits to be present on a single item.

The maximum rollable Tier is Exeptional (Tier 4), however they can be upgraded to Exquisite (Tier 5) and finally Perfect (Tier 6) with the use of the Orb of Conflict. The best possible outcome on an item is to have a Perfect (Tier 6) and Exceptional (Tier 4) implicit modifier at the same time. Be aware that this process can be very expensive! If you're on a budget you can instead go for Lesser (Tier 1) and Greater (Tier 2). A desired mod has 3-5% chance to be rolled with Lesser currencies and 1-3% chance with Greater currencies and above as more mods are introduced into the pool. The process of achieving this as cheaply as possible is:

  1. Use Grand Eldritch Ember or Grand Eldritch Ichor until the desired implicit which you wish to upgrade to perfect has rolled on the item.
  2. Apply a single Exceptional Eldritch Ichor or Exceptional Eldritch Ember of the opposite influence.
  3. Use an Orb of Conflict in hopes of upgrading the desired modifier.
  4. If the desired modifier has upgraded, re-apply Exceptional Eldritch Ichor or Exceptional Eldritch Ember. Repeat this process until it is Perfect (Tier 6).
  5. If the desired modifier has downgraded, use an Orb of Conflict until it upgrades.

Eldritch Orbs

Ichors & Embers are used to provide "Dominance", i.e. if a Lesser Eldritch Ember is applied to an item without any Eater of World influence, then Searing Exarch will be dominant. If a Greater Eldritch Ichor is applied to an item with a modifier granted by Lesser Eldritch Ember, then Eater of World will be dominant. This allows for items to be modified by Eldritch Chaos Orb, Eldritch Exalted Orb & Eldritch Orb of Annulment which provide a much more affordable way of crafting compared to meta-crafting with Exalted Orb & Orb of Annulment. Note: Eldritch influence cannot be applied to Shaper, Elder, or Conqueror influenced items.

The process of crafting items with Eldritch Currency is reversed whether you begin on it's prefixes or suffixes. Let's consider the example of crafting a Helmet with (9-10%) increased Mana Reservation Efficiency of Skills , obtainable as a Suffix through Deafening Essence of Loathing. This is a powerful mod for many builds, but doesn't constitute a good item on its own. Here are the steps to create a great outcome:

  1. Use a Deafening Essence of Loathing until you roll a 2nd desirable suffix modifier.
  2. Craft Suffixes Cannot be Changed and proceed to use a T4 Aisling on the item in hopes of getting a useful suffix.
  3. Repeat step 2 until you have two useful suffixes in addition to your Deafening Essence of Loathing modifier.
  4. Apply Lesser Eldritch Ember or higher to ensure Searing Exarch is dominant on the item.
  5. Block/craft a modifier with the highest weight on the item with the crafting bench. This is usually a defense modifier such as % Increased Armour and Evasion (this depends on the base-type you are crafting on and what mod you wish to augment).
  6. Use an Eldritch Exalted Orb in hopes of augmenting a modifier you want.
  7. If the desired modifier did not roll, remove the craft from step 5 and use an Eldritch Orb of Annulment to remove it.
  8. Repeat steps 5 - 7 until you augment the desired modifier.
  9. Finish the item by removing the block craft and using a Eldritch Exalted Orb to get any usable 5th prefix.
  10. Craft the final prefix with the Crafting Bench.

Influenced Crafting & Currencies

Influenced base types have an extended pool of exclusive modifiers. They can be recognized by their visual effect, icons, and their appearance on custom loot filters. Shaper and Elder Influenced items are primarily found in their respective boss fights and invitations, but also on Shaper/Elder occupied maps or if you use Rusted Shaper Scarab or Rusted Elder Scarab. Conqueror influenced items can be found in Conqueror occupied maps as well as in their respective boss fights and Invitations.

Influence TypeFeaturesRelated CurrencyInfluence Modifier
Crusader item  SymbolCrusader's Exalted OrbCrusader modifiers

Shaper item  SymbolRusted Shaper Scarabs, Delve rewards and IncubatorsShaper modifiers
Elder item SymbolRusted Elder Scarabs, Delve rewards and IncubatorsElder modifiers

The following are currencies used to augment and modify influenced modifiers and influenced crafting bases. Note: you cannot apply a Conqueror's Exalted Orb to an already influenced item.

  • Hunter's Exalted Orb adds Hunter influence and a new Hunter modifier to a rare item.
  • Crusader's Exalted Orb adds Crusader influence and a new Crusader modifier to a rare item.
  • Redeemer's Exalted Orb adds Redeemer influence and a new Redeemer modifier to a rare item.
  • Warlord's Exalted Orb adds Warlord influence and a new Warlord modifier to a rare item.
  • Awakener's Orb destroys an item, applying its influence to another item of the same item class. The second item is reforged as a rare item. with both influence types and new modifiers.
  • Orb of Dominance removes one influenced modifier from an item with at least two influenced modifiers and upgrades another influenced modifier. Upgrading a modifier of the highest tier transforms the modifier into an elevated modifier. Attempting to upgrade an elevated modifier rerolls its values. They can be used on Body Armours, Boots, Gloves and Helmets.

The Awakener's Orb in combination with the Orb of Dominance can be used to create some of the most powerful items in the game. This method of crafting, however, makes it very difficult to finish items outside of two desired influenced modifiers. This results in a more expensive process if the item is to be finished. Its most common use is where certain modifiers heavily out-scale those of non-influenced modifiers, such as:

  • You have Tailwind if you have dealt a Critical Strike Recently
  • % chance to gain Elusive on Critical Strike
  • Enemies you Kill have a % chance to Explode, dealing a tenth of their maximum Life as Physical Damage
  • % chance to gain a Frenzy Charge on Hit
  • +#% to Spell/Attack Critical Strike Chance
  • Adds (1-2) to (3-4) Cold Damage to Attacks with this Weapon per 10 Dexterity

The Orb of Dominance can be used to substantially improve or transform influenced modifiers on an item. It requires at least 2 influenced modifiers to be present for it to upgrade one while deleting the other, giving you a 50/50 chance to hit the right one. This process gets very costly quickly, and is only used for the most endgame items that can potentially devour hundreds of Exalted Orbs. Once a modifier is elevated, a second base with an already elevated modifier can be bought or made with the same process for them to be merged together with an Awakener's Orb. The remaining modifiers on the item are then rerolled with an unpredictable outcome outside of the two influenced mods.

  • We start with Orb of Dominance in order to elevate the "Enemies you Kill have a % chance to Explode, dealing a tenth of their maximum Life as Physical Damag" Crusader Prefix. We do the same on a second base with the Hunter % increased maximum Life Prefix. Note: the item needs to have the highest Tier of the modifier in order to reach the Elevated Tier with this process! 
  • After successfully upgrading both mods to Elevated, we use an Awakener's Orb to combine them on the same item. Beware: The order of which items you click on matters, as the first will be destroyed and the second will house the new mods!
  • Now we have have an item with two extremely strong Prefixes. In order to continue, we can use the Meta Crafting steps described above. In our case, we would make sure we have our two desired Prefixes as well as in addition to an open Prefix.
  • Next we Bench Craft Prefixes Cannot be Changed and use an Aisling T4 on our item until we get a Veiled Prefix in hopes of Unveiling a useful Prefix.
  • Craft Prefixes Cannot be Changed and proceed to using a Harvest Attack/Caster Reforge to guarantee one in two tiers of #% to Spell/Attack Critical Strike Chance

Harvest Crafts

Harvest crafting has become one of the main ways to create Prefix or Suffix-loaded base items. It also finishes items thanks to the fact that Harvest reforges respects Meta-Mods unlike Fossils and Essences. This means if you craft Prefixes Cannot Be Changed on an item and use a Harvest reforge on it, your item will retain its Prefixes and roll Suffixes individually while guaranteeing a single modifier with the reforge's tag. Additionally Harvest offers so-called "more likely" crafts that boost the weight of a specific mod group by 10x on top of the already guaranteed tagged modifier. Lastly, augments are very rare crafts which can be found in Harvest. These act like Exalted Orb for a specific tag. For example, you may find a Life Augment allowing you to Exalt a life modifier onto a non-influenced item.

There are many great ways to use Harvest for advanced crafting, however it is also very useful for personal character progress and profit crafting. Harvest makes Medium Cluster Jewel & Large Cluster Jewel crafting easier as it guarantees specific mods and can also help grant more mods of a specific type. The type of craft varies depending on the type of Cluster Jewel you are trying to craft. Make sure to refer to Craft of Exile's Cluster Jewel section to get an idea of which reforge is best for the type of jewel you're trying to craft.

Harvest is also great for crafting flasks and can be a great avenue for profit in both early and endgame. The 3.16 Flask changes made Flask crafting with Orb of Alteration & Orb of Augmentations a pain as getting a combination of two high tier prefix + suffix combination on the right type is very tricky. Harvest guarantees one of the two mods, making it an invaluable tool for creating a useful Flask at a very low cost. Typical use cases are:

  • A reforge Defense can be used on both Jade Flask & Granite Flasks to obtain % Increased Armour During Flask Effect & % Increased Evasion During Flask Effect.
  • A reforge Critical can be used on Diamond Flasks to obtain the % chance to gain a Flask Charge when you deal a Critical Strike and % increased Critical Strike Chance during Flask Effect mods.
  • A reforge Speed can be used on Quicksilver Flask to obtain % increased Movement Speed during Flask effect or on Silver Flask to obtain % increased Attack/Cast Speed during Flask effect.

There are many more uses for Harvest that this guide cannot cover, so if you wish to learn more about its mechanics and offerings, read our in-depth Harvest Explanation guide!

Delve Fossils

Fossils are one of the many ways to create great items as they provide a 10x weight multiplier to specific tags which are relevant to the Fossil type used in a craft. They also allow for certain types to be blocked, allowing for interesting combinations to guarantee certain modifiers on specific item types. There are special types of Fossils which grant unique modifiers. A good example of a useful Fossil combination is: Corroded Fossil + Jagged Fossil + Metallic Fossil on an Item Level 64+ Bow for a 1/8 chance to land both +2 to Level of Socketed Bow Gems and and +1 to Level of Socketed Gems. Those two mods would cost 1,131 Chaos Orbs!

Here are the Fossils which can be found in Delve:

Delve Fossil Types

The concept is rather simple: you use a Vaal Orb on an item you want to corrupt, which produces a random effect on it with no possibility of going back.

A Corrupted Item

In most cases corrupted items cannot be modified further, meaning you can't apply any crafting currency on them anymore. A corrupted item has the red Corrupted tag at the bottom of its modifiers list to notify the player.

There is one exception to that rule: you can still change sockets and links using your Crafting Bench at the cost of additional Vaal Orbs on top of the usual Orb of Fusing fee. This is usually referred to as Vorici Linking/Coloring as a remnant of the old Master system, when getting the master Vorici to level 8 was the only way to access these crafting recipes.

Corrupting an Item has several different outcomes weighted equally:

  • Adds a random implicit modifier.
  • Turns 1 or more sockets into white sockets.
  • Bricks the item into a random rare item.
  • Nothing happens.

Craft of Exile

Craft of Exile is the most comprehensive tool currently available for free for all Path of Exile players. It hosts a comprehensive list of every modifier on all item types and bases, as well as a crafting simulator and emulator. This allows for crafting projects to be diligently planned out and simulated to get an idea of the average amount of patience and currency required to take on a specific crafting project.

The emulator allows users to craft item the same way they would ingame, but without any of the costs. This removes much of the risk of experimentation and empowers users to seek out new crafting methods. This is the most important tool for any aspiring crafter and must be used before any project is undertaken!

Additionally Craft of Exile allows users to find the best and cheapest possible combination of Fossils needed to roll a combination of selected affixes. This allows users to make rational decisions on what the best course of action is for their crafts.

To do this first select your preferred item base and type, then select your preferred crafting method as Fossils, and finally click on the compute best selection button. The website will undergo a simulation to find the best and cheapest combination of Fossils needed to obtain the selected mods.


  • Items are the core of Path of Exile. They are what make characters strong and they represent your progress throughout the game. Crafting is the way to obtain those items; Path of Exile does a great job at providing many different ways for players to create them.
  • Crafting creates a market in which players who dedicate themselves to crafting can make a lot of currency. This allows other players to simply farm the currency and buy items.
  • New crafting methods are discovered every league, and Path of Exile introduces new currencies for crafters to use, making the process everchanging and exciting!
  • Thanks to tools like Craft of Exile, players can familiarize themselves with item bases, mods and tags while simulating crafting projects without incurring any costs.
