Not to be confused with stats.
For a list of item modifiers, see List of item mods.

Modifiers generally change various aspects of the entity they are affecting. Most commonly modifiers apply stats, however they can also apply buffs or grant skills and can often be found on items, monsters, strongboxes or areas.

A modifier should be seen as an instance of change applied to an entity. A basic modifier does nothing on its own, it is given the effect by the associated stats (and their values), buffs and skills.

Mechanics overview

A modifier applies statistics, a buff or grants a skill to an entity. Modifiers are specific to items, monsters, strongboxes or areas.

Since not all statistics have a visible text, it is possible that some effects are granted by the modifier but are not visible to the player. On the wiki, some of these effects have a custom text specific to the wiki and are noted with (HIDDEN) in the description. In particular area and monster effects may be hidden from the player.

Modifiers can either be innately applied (as "implicit" modifier) to entities, be granted under specific conditions or randomly generated.

Some specific circumstances like the rarity of a monster, being touched or possessed by a Tormented Spirit, etc can also apply modifiers innately without them being randomly generated.

Modifier generation is gated by specific conditions that govern if and how likely a modifier is going to appear:

  • Mod domain governs the type of entity the modifier is going to appear and may confer some specific rules (such as the number of affixes).
  • Mod generation type determines how the modifier is generated, for example whether it's a prefix, suffix, corrupted or always applied (like on unique items)
  • Mod level governs the minimum required level of the entity for a modifier to appear (i.e. the item level, monster level, area level), and for items only raises the item's level requirement to 80% of its value
  • Mod group (mod family) prevents other modifiers from the same family to be randomly generated on the same entity[1]
  • Tags in conjunction with weights are used to further restrict the types of modifiers that can appear and set the relative chance to be randomly applied. (for example, shaper and elder get a corresponding tag)

The values of stats include a minimum and maximum value, which is most commonly used on items - the actual value of the stat in the cases where minimum and maximum are not the same will be randomized within with equal chances, so for example a Stat with a minimum value of 1 and a maximum value of 3, can either be 1, 2 or 3 at 1/3 chance for each value.

If a buff is specified, Modifiers also include a value for the buff, but unlike for Stats it is not randomized and fixed.

If a skill is specified, the specified skill (at the specified level) will be granted to the relevant entity. The modifier does not include values for the skill other then the level as they're defined by the skill itself. Often this is found on items, where they grant skills, such as The Whispering IceThe Whispering Ice

unique item.

Local and global

Modifiers can be categorized as "local" or "global" modifiers.

Local

The concept of "local" modifiers has broadened since its original technical definition[2]. This can be seen by the use of (local) in the trade site for modifiers that failed to meet the original criteria of just base stat modifications, like #% chance to Poison on Hit.

Currently, local modifiers can be identified by fulfilling any of the following requirements:

  1. Item Properties: The modifier is unconditional and could affect innate properties of the item
  2. Hand-specific: The modifier explicitly states that it applies to the item, such as "with this Weapon"
  3. Weapon Hit Effect: The modifier is on a weapon and could apply on a hit with a generic weapon, unrelated to the numeric damage dealt

Item Properties: Item properties encompass all default properties of an item, including its base stats, attribute and level requirements, and sockets and links. Base stats can be found at the top of the item's tooltip. For example, #% increased Attack Speed and Adds # to # Physical Damage on a weapon will modify the "Attacks per Second" and "Physical Damage" stat on the weapon itself. Certain stats may not be immediately obvious, as most base items have that stat's default value at 0. For example, Adds # to # Fire Damage on a Solarine BowSolarine BowBow
Physical Damage: 16-24
Elemental Damage: (121-133) to (184-197)
Critical Strike Chance: 5.50%
Attacks per Second: 1.30
Requires Level 70, 212 DexAdds (121-133) to (184-197) Fire Damage
directly adds to the weapon's base damage, of which Fire Damage is usually 0 for weapons. Default base stats are displayed in white, while modified base stats are displayed in blue (with the exception of fire/cold/lightning/chaos damage on weapons, which are colour-coded based on their damage type and have a base stat of 0).

Quality effects are always considered local as they affect an item's base stat(s). Catalyst quality effects are also local, which instead functions as #% increased X Modifier magnitudes modifiers, which are the only type of local modifier that can be found on jewellery (as jewellery only have implicit modifiers, level requirements, and sometimes sockets as base stats).
The following is a list of local base stat modifiers which can be quickly identified as local, if unconditional (Note that this list does not cover all local mods, just local mods that affect base stats):
  • Weapons: #% increased Physical Damage, Adds # to # X Damage, #% increased Attack Speed, #% increased Critical Strike Chance, +# metres to Weapon Range
  • Any other type of #% increased Damage is never local, as generic weapons only have base Physical Damage.

Hand-specific: Modifiers that include "with this Weapon" or "Main/Off Hand" should be considered local, despite being conditional, as they only apply to attacks using that specific hand/weapon. These types of modifiers are technically global modifiers that apply locally to one or both hand(s), and therefore cannot be scaled by other local increases[3].

Weapons that add specific damage to the main or off-hand also display these values in their base stats as if combined, although they display correctly in the character stats screen (C by default) and skill tooltips as well as being correctly handled for Battlemage. Other main/off-hand stats like (50-70)% more Main Hand attack speedWingsOfEntropyMainHandAttackSpeedFinalUnique__1_
Intrinsic
(50-70)% more Main Hand attack speed
do not visually affect the base stats but are correctly reflected in the character stats screen. Two-handed weapons are always considered as being in the main hand (left), while shields are always considered in the off-hand (right).

Weapon Hit Effect: Stats on weapons that apply on an attack hit with a generic (modifier-less) weapon (e.g. #% Chance to Poison on Hit, #% Chance to Maim, #% of Physical Attack Damage Leeched as Life) are considered local. Flat modifiers to accuracy or chance to hit on weapons are also considered local, as chance to hit is hand-specific and determined on hit. While Poison and Bleeding chance are local, Ignite chance is always global, as generic weapons do not have base fire damage and therefore cannot ignite.

Global

Global modifiers encompass all other modifiers that are not local. All conditional stats are global except for the main/off-hand stats listed above[4]. Global stats never modify an item's base stats and instead apply to the character's stats, and therefore cannot interact directly with other local modifiers. For example, the damage from Adds # to # Physical Damage on a weapon is scaled by #% increased Physical Damage and quality on a weapon, but Adds # to # Physical Damage to Attacks from the ring is not (as rings do not have base damage) and added separately in addition to the weapon's base damage before calculating any other global increased/more modifiers. Modifiers that state "Global" are always global.

Hybrid modifiers (modifiers with more than one line per stat) treat each line independently. A hybrid modifier can have both local and global parts, such as of Tacati - 30% chance to Poison on Hit, (26-30)% increased Chaos Damage (Suffix).

Terminology

In general modifiers are referred to as such, however there are many special cases of modifiers that correspond to specific sets and Modifiers#Conditions :

Term Explanation
Implicit Any innate modifier of an entity. Most commonly used in reference to items.

On items, this is the effect above the line separating modifiers. They can also be replaced via certain effects such as corruption.

Explicit Any generated modifier of an entity that has a non-normal rarity (i.e. magic, rare or unique).

May be randomized (such as prefixes, suffixes) or fixed (e.x. on unique items).

Prefix Refers to the "Prefix" generation type.

On magic entities, these will have a name visible before the name of the entity itself. For example, ViciousVicious
Prefix
(85-109)% increased Physical Damage
on a Broad SwordBroad SwordOne Handed Sword
Physical Damage: 15-21
Critical Strike Chance: 5.00%
Attacks per Second: 1.45
Weapon Range: 1.1 metres
Requires Level 15, 30 Str, 30 Dex40% increased Global Accuracy Rating
will show as Vicious Broad Sword.

Suffix Refers to the "Suffix" generation type.

On magic entities, these will have a name visible after the name of the entity itself. For example, of the Lynxof the Lynx
Suffix
+(13-17) to Dexterity

Physical Damage: 15-21
Critical Strike Chance: 5.00%
Attacks per Second: 1.45
Weapon Range: 1.1 metres
Requires Level 15, 30 Str, 30 Dex40% increased Global Accuracy Rating

Examples

Types of modifiers

Implicit modifiers

Implicit modifier on items
Implicit modifier on items

Implicit modifiers always spawn on entities before the addition or change of additional modifiers (for example by changing the rarity).

On monsters, implicit modifiers can be very commonly found. For example, some monsters are granted damage conversion which converts their inherent damage to that of another element. However, on unique monsters and bosses implicits are most notable - for example most bosses are granted a boost to their item rarity and item quantity as well as other bonuses such as on Atziri.

On items, visible implicit modifiers are most commonly found on:

Shields and body armour also commonly have a hidden movement speed penalty modifier.

Unlike the implicit modifiers on monsters, the implicit modifiers on equipment can be by altered in various ways:

  • Blessed OrbBlessed OrbStack Size: 20Randomises the values of the implicit modifiers of an itemRight click this item then left click another item to apply it. - rerolls the range of the stats found on the implicit modifiers.
  • Vaal OrbVaal OrbStack Size: 20Corrupts an item, modifying it unpredictablyRight click this item then left click an item to corrupt it. Corrupted items cannot be modified again. - Corruption can add or replace an implicit modifier depending on the item type.
  • Eldritch currency - Eldritch Ichors and Eldritch Embers will replace the item's implicit modifier with an Eater of Worlds implicit modifier or a Searing Exarch implicit modifier respectively, while retaining any Eldritch modifiers of the other type.
  • Using a Resonator with a Gilded FossilGilded FossilStack Size: 10Item is overvalued by vendorsPlace in a Resonator to influence item crafting. will add an Item sells for much more to vendors implicit to the item. This does not overwrite or affect the item's current implicit modifier.
  • Synthesised items have up to three different random implicit modifiers, including on items that normally don't have an implicit modifier. You can transform an item into a synthesised item via Harvest crafting.
  • Certain Harvest crafting options allowed you to set a new implicit modifier on jewels. These can now only be found on legacy items in permanent leagues.

Certain unique items also have special interactions with implicits:

  • Greatwolf TalismanGreatwolf TalismanTalisman Tier: 4<Two random talisman implicit modifiers>CorruptedThe wolf greeted the king,
    In the light of the harvest moon.
    The wolf offered the strength of the wild,
    And the king paid for it in blood.
    - has two randomly chosen talisman implicits.
  • String of ServitudeString of Servitude

    Level Requirement reduced by 100 (Hidden)
    CorruptedFor the Vaal, the relationship between slave and master was as intimate and volatile as that of lovers.
    - triples the effect values of implicit modifiers.

Enchantments

Enchantments are similar to implicit modifiers, but are granted to the item by specific means. Enchantments have their own mod slot on items and do not use the implicit mod slot.[5] Most items can have up to one enchantment at a time. Any level of rarity, even unique items, can be enchanted. Mirrored cannot receive an enchantment.[6] They are always fixed values, so Blessed OrbsBlessed OrbStack Size: 20Randomises the values of the implicit modifiers of an itemRight click this item then left click another item to apply it. have no effect on them.[7] Applying an enchantment on an already enchanted item replaces the old enchantment with the new one. Enchantments can be removed using the Crafting Bench recipe. This does not include maps, they can only be enchanted once.

  • Rings, Amulets, and certain Blight league uniques, as well as Blighted maps and Blight-ravaged maps, can be Anointed with Oils to give it an enchantment.
  • Cluster Jewels have two (for small jewel and legacy medium and large jewels) or three enchantments: One that determines what stat the small passives gives (which determine what mods the jewel can roll), one that determines how many passive skills are in the cluster, and one that determines how many jewel sockets it has (for Large and Medium Cluster Jewels).
  • Certain Harvest crafting options allows you to add enchantments to weapons, body armours, maps and flasks. Read harvest crafting for details.
  • Weapons and body armour with enchantments are possible rewards in Grand Heists. The enchantments can be added by using Tailoring OrbTailoring OrbStack Size: 20Adds or replaces an enchantment on a body armour

  • Delirium orbs can be applied to maps to make it Delirious, adding a global Delirium effect and reward to it.
  • Certain Blight-related Atlas passive skills can cause maps to drop with an Area contains a Blight Encounter enchantment.
  • Labyrinth Enchantments were obtained from the Divine Font at the end of the Labyrinth. Gloves, Boots, Helmets, and Belts could receive Labyrinth enchantments, depending on the difficulty. Labyrinth enchantments can no longer be acquired and can only be found on legacy items that already have one in permanent leagues.

Scourge mods

If an item becomes Scourged using the Blood Crucible, it gains two Scourge implicit modifiers, one positive and one negative. Scourge mods are separate from implicit mods and enchantments. Blood Crucible upgrades can cause an item to gain additional Scourge implicit mods. This mechanic is not yet added to the core game.

Explicit modifiers

Explicit modifiers are generally dynamically generated by changing the rarity of the entity or by other modification.

The number of affixes given by rarity depends on the rarity class:

  • Magic - random modifiers based on conditions: (0 to 1) prefix and (0 to 1) suffix
  • Rare - random modifiers based on conditions: (1 to 3) prefixes and (1 to 3) suffixes (but always at least 3) with the exception of jewels which can only have (1 to 2) prefixes and (1 to 2) suffixes
  • Unique - non-random, fixed modifiers based on the unique entity

Monsters have different means of receiving modifiers:

  • Magic packs of monsters spawn with one Monster modifier
  • Rare monsters spawn with 2-4 Monster modifiers
  • Normal and Magic monsters may be touched by a Tormented Spirit, giving a Torment 'Touch' modifier
  • Rare and Unique monsters may be possessed by a Tormented Spirit, giving a Torment 'Possession' modifier
  • Rare monsters trapped in an Essence can have an 'Essence' modifier
  • Rare Beasts, which are found in Einhar missions, can have one or two Bestiary mods.
  • Magic and Rare monsters receive a Delirium modifier during a Delirium encounter; they are removed when the encounter is over
  • Picking up a Talisman gives monsters a Talisman modifier (Talisman league only as well as specific Delve node that contains a Talisman-possessed monster)

On items, modifiers can be changed by spending currency:

Areas may receive modifiers depending on how they were created unlike items, monsters or strongboxes:

  • Corrupted areas as they have the 'secret_area' tag will receive (0 to 1) prefixes and (0 to 1) suffixes that satisfy that tag
  • Areas created with Map items receive the modifiers on the map they were created with
  • Areas created through a Map device may receive mods from placing map fragments in the device
  • The current league(s) or other server-wide effects (from races for example)
  • With Tempest active in the area, the area may receive a tempest modifier

Conditions

Modifiers usually include conditions which are used to determine how they appear. These are generally used to govern the creation of explicit modifiers on entities.

Domain

The domain of a modifier specifies what kind of game object it applies to. The domains are primarily reverse engineered, as detailed information has been removed from the game files.

Mod Level

The required level of the relevant entity. For example, this can be the required item level or a monster level.

However, there are cases where this is not respected: in particular this is the case for any mods that are directly given to other entities, such as implicit mods including enchantments or monsters with innate mods.

The mod level is also a factor in calculating the level requirement of items; raising the level requirement up to 80% requirement of the mod (with the requirement rounded down to the nearest whole integer). In particular this is the case for mods on unique items and for enchantments

For example, Seven-League StepSeven-League Step
Rawhide Boots
Evasion: (13-18)50% increased Movement Speed
Level Requirement reduced by 100 (Hidden)
"Death can be outrun with these, but beware!
In running from death, you may forget to live."
- Icius Perandus, Antiquities Collection, Item 202
normally has a level requirement of 1, however after adding a legacy 0.5% of Damage Leeched as Life if you've Killed Recently enchantment from the Labyrinth its level requirement increases to .

Group/family

Each modifier belongs to one or more groups (or families). These restrict which modifiers may appear on an object together.[1] Only one modifier from any given group may appear on an object; in other words, all modifiers belonging to a group are mutually exclusive with one another.

This is often used used to influence the crafting of items, where players will add a mod from an undesired group of modifiers to block it. This means the undesired mods in that group will not be added when crafting currency is used. Together with the item level requirements, this creates the "tiered" system of modifiers.

Tags

Mods use the internal Tag system to determine on which entities they can appear and how likely they are to appear on entities. Tags are classified as spawn weight tag and mod tag:

Spawn weight tag

Spawn weight tag primarily functions like this:

  • Find the Tags on the basetype.
  • Match the Tags against the mod's list of tags.
  • For the found mods get the associated spawn weighting of the tag.
  • If the spawn weighting is zero, discard the mod, otherwise use it.
  • If multiple tags apply, the left-most tags are most important, where the right most tags are the least.

So, for example:

  • Glorious PlateGlorious PlateArmour: (776-892)Requires Level 68, 191 Str has the tags str_armour top_tier_base_item_type body_armour armour default.
  • Assassin's GarbAssassin's GarbEvasion: (737-811)Requires Level 68, 183 Dex3% increased Movement Speed has the tags dex_armour top_tier_base_item_type body_armour armour default.
  • The mod ImpregnableImpregnable
    Prefix
    (92-100)% increased Armour
    has the spawn weights .
  • Result for Glorious PlateGlorious PlateArmour: (776-892)Requires Level 68, 191 Str: The mod can spawn because it has the tag str_armour and a positive spawn weight.
  • Result for Assassin's GarbAssassin's GarbEvasion: (737-811)Requires Level 68, 183 Dex3% increased Movement Speed: The mod can not spawn because only default matches and its spawn weight is 0.

Mod tag

Mods can be found tagged with mod tags. A non-exhaustive list can be found below. Some mods do not have any tags. These tags can interact with Catalysts, Fossils, Harvest crafting, and Heist enchantments.

In the table below, the tags on the top row have associated Harvest crafts. As a result, they also have associated tag colours. The tags on the bottom row have neither.

Lightning Cold Fire Physical Chaos Life Caster Attack Speed
Elemental Resource Mana Damage Gem Attribute Bleed Poison Ailment Aura Curse Defences Minion Critical

Metamods

The metamods of Spellcraft - Cannot roll Attack Modifiers (Suffix) and of Weaponcraft - Cannot roll Caster Modifiers (Suffix) can interact with Harvest crafting, Exalted OrbsExalted OrbStack Size: 20Augments a rare item with a new random modifierRight click this item then left click a rare item to apply it. Rare items can have up to six random modifiers., Orbs of AnnulmentOrb of AnnulmentStack Size: 20Removes a random modifier from an itemRight click this item then left click on a magic or rare item to apply it., and the beastcrafting recipes "Add a Suffix, Remove a Random Prefix" (Farric Lynx Alpha) and "Add a Prefix, Remove a Random Suffix" (Farric Wolf Alpha).

For example, when an Exalted Orb is used on an item with the of Spellcraftof Spellcraft
Suffix
Cannot roll Attack Modifiers
, the Exalted Orb cannot add modifiers with the "Attack" tag. Similarly, when an Orb of Annulment is used on an item with the of Weaponcraftof Weaponcraft
Suffix
Cannot roll Caster Modifiers
modifier, it will not remove any modifiers with the "Caster" tag.

  • This behaviour is specific to Orbs of Annulment. The metamod does not protect mods from removal when used with other crafts that remove a single modifier, such as beastcrafting, Harvest, or Veiled Orb.

Some crafting methods ignore or cannot be used with metamods. Awakener's OrbAwakener's OrbStack Size: 10Destroys an item, applying its influence to another of the same item class
The second item is reforged as a rare item with both influence types and new modifiers
Right click this item, then left click the item you wish to take the influence from, then left click an item of the same item class you wish to apply it to.
s[8] ignore them. Essences[9] and resonators socketed with fossils may not be used on items with metamods.

Catalyst

Quality applied to jewellery, such as rings, belts, and amulets, can only be applied with Catalysts. Each type of Catalyst will apply a different type of quality which increases magnitudes of modifiers with the tags associated with the quality type.

For example, when a Fertile CatalystFertile CatalystStack Size: 10Adds quality that enhances Life and Mana modifiers on a ring, amulet or belt
Replaces other quality types
Right click this item then left click a ring, amulet or belt to apply it. Has greater effect on lower-rarity jewellery. The maximum quality is 20%.
is applied to jewellery, it will apply a quality that increases the magnitude of modifiers with the Life or Mana tags, up to 20%. A modifier normally granting "+79 to Maximum Life" on the item will be enhanced to instead grant "+94 to Maximum Life", and a modifier normally granting "Non-Channelling Skills have -7 to Total Mana Cost" will be enhanced to instead grant "Non-Channelling Skills have -8 to Total Mana Cost". Modifiers enhanced this way will round down decimal values.

Fossils multiply the weights of modifiers that match the type of the fossil, For example, Metallic FossilMetallic FossilStack Size: 20More Lightning modifiers
No Physical modifiers
Place in a Resonator to influence item crafting.
s will multiply the weight of modifiers with the Lightning tag by 1000%, and the modifiers with Physical tags by 0%. Effectively, this will result in modifiers with the lightning tag to appear 10x more oftenwhen the item is rolled, and modifiers with the physical tag never rolling.

Heist Enchantments

Many heist-exclusive enchantments can modify the magnitudes of modifiers of certain tags, both positively and negatively. These enchantments can be acquired either through the use of a Tailoring OrbTailoring OrbStack Size: 20Adds or replaces an enchantment on a body armour
This may reforge the body armour's sockets
Right click this item then left click on the item you wish to modify.
on a body armour, use of a Tempering OrbTempering OrbStack Size: 20Adds or replaces an enchantment on a weapon
This may reforge the weapon's sockets
Right click this item then left click on the item you wish to modify.
on a weapon, or found already rolled as an item in a Curio Display at the end of a Blueprint wing. (All Grand Heist layouts with "Enchanted Rare Body Armour" and "Enchanted Rare Weapon" as a reward type).

For example, the enchantment 8% increased Explicit Life Modifier magnitudes will enhance a modifier that normally grants "+100 to Maximum Life" to granting "+108 to Maximum Life". Some Heist enchantments come with downsides. The hybrid modifier 10% increased Explicit Life Modifier magnitudes + 25% reduced Explicit Speed Modifier magnitudes will increase the magnitudes of modifiers with the Physical tags by 10%, but reduce the magnitudes of modifiers with the Speed tag, such as 19% increased Attack Speed by 25%.

Harvest Crafting

Many Harvest crafting methods interact with modifier tags.

The craft "Reforge a Rare item with random modifiers, including a (tag) modifier" will completely reforge the modifiers of a Rare item, similar to a Chaos OrbChaos OrbStack Size: 20Reforges a rare item with new random modifiersRight click this item then left click a rare item to apply it., while guaranteeing a modifier with the specified tag. If there are no valid tags in the mod pool to roll for the selected item, the craft cannot be used. The add/remove crafts work as expected.

The craft "Change a modifier that grants (Element) Resistance into a similar-tier modifier that grants (Different Element) Resistance" will swap a resistance modifier of a certain element into that of another one.

  • This method works for modifiers beyond the generic "+#% to (Element) Resistance". It also works for the incursion architect-exclusive resistance-granting modifiers. For example, the modifier of Puhuarte - +(46-48)% to Cold Resistance, (30-50)% increased Damage with Hits against Chilled Enemies (Suffix) can be reforged into of Puhuarte - +(46-48)% to Fire Resistance, (45-52) to (75-78) added Fire Damage against Burning Enemies (Suffix) and vice versa. This can be used to swap to another, more desired mod, or to effectively "divine" the modifier. This is generally more desirable than with the normal resistance rolls, as modifiers with "(30–50)% increased Damage with Hits against Chilled Enemies" have much higher roll variance and thus more value can be obtained.
  • This craft preserves the tier, but not the roll within that tier. This property may be used to reroll a higher value intentionally, by switching back and forth between your desired element and another one. Each time you switch back to the type that you want, the modifier values will be re-rolled. This method is recommended for builds with high levels of investment, as usually a few % of resistance is not worth spending the lifeforce.

Version history

Version Changes
3.19.0
  • Fixed a bug where Recombinators were ignoring modifier families in certain situations.
3.15.2
  • Added crafting bench recipes for adding a specific Enchantment to a Flask. There are recipes for all of the possible Enchantments obtained through Instilling Orbs. These recipes are unlocked alongside the Rank 3 Movement Speed crafting option in Oriath (and will already be unlocked for you if you have obtained the Rank 3 Movement Speed crafting option in that league).
  • Added a crafting bench recipe to remove Enchantments from an item. This recipe does not need to be unlocked and is always available.
3.12.0
  • Item modifier tags have been entirely reworked with a goal in mind of consistency and simplicity. These changes have negligible impacts to the odds of various modifiers appearing on rare items naturally, but may have impacts to the results of certain crafting methods. A list of all modifiers and their associated tags can be found here.
  • As a result of the above changes, several fossil descriptions have changed slightly.
3.11.0
