Mods are short for Modifcation but in Warframe they are intended to be symbolic of Orokin-derived technology. "Lost tech"."}}</ref> or '''Modules''', are the upgrade system in [[WARFRAME]] in the form of special cards that can be equipped on [[Warframes]], [[weapons]], [[companions]], and [[:Category:Vehicle|vehicles]] to enhance [[damage]], power, survivability, speed, mobility, [[Companions#Precept Mods|precepts]], and utility.

The Mods system is accessible after the completion of "Liberate the imprisoned arms dealer" tutorial mission from the [[Vor's Prize]] [[Quest]], by installing the Mods Segment reward from said mission onto the [[Orbiter]], which will permanently unlock the Mods system for use via the [[Arsenal]] ("Upgrade").

From the [[Arsenal]], you can install mods on your equipment, but they are limited by the equipment's mod capacity that depends on the level of the equipment. Any mod can be installed/removed freely and can be applied to several equipment at the same time. You can also upgrade your mods by using {{Ec|[[Endo]]}} and {{Cc|[[Credits]]}} through the process of [[Fusion]].

==Acquisition==
*'''Drops from enemies:''' Almost all enemies have a chance of dropping a mod, selected from their [[Drop Tables|drop table]] ''(visit their respective pages for more details)''. The usual mod drop chance is '''3%''' (can be doubled with [[Mod Drop Chance Booster]]s) but may differ depending on the type of enemy. Typically if a mod drops from a specific enemy:
**'''75.88%''' of the mod drops will be Common.
**'''22.11%''' of the mod drops will be Uncommon.
**'''2.01%''' of the mod drops will be Rare.
*'''Drops from canisters:''' Mods can be obtained from the [[Orokin Void]] canisters and more commonly from treasure room canisters. Modules obtained are randomly chosen for every player.
*'''[[Mission]] rewards:'''
**Most non-endless mission types may offer a mod, [[blueprint]], {{Resource|Endo}}, or {{Resource|Credits}} as one of the mission rewards upon completion.
**Every rotation of endless missions (e.g. [[Defense]]) will offer a reward chosen randomly from a drop table, which may include mods.
**Completing a [[Nightmare Mode]] mission rewards a [[:Category:Nightmare Mode Mods|Nightmare mod]].
**Completing [[quest]] missions may reward a mod.
*'''Events & Tactical [[Alert]]s:''' Specific mods that are acquired as a reward for these activities are, in general, also obtainable later, by other means (typically, [[Baro Ki'Teer]] will sell them).
*'''Vaults:'''
**Opening an [[Orokin Vault]] always rewards a [[:Category:Corrupted Mods|Corrupted mod]].
**Opening an [[Isolation Vault]] may reward a [[Necramech]] mod. 
*'''[[Transmutation]]'''
*'''[[Market]]:''' Purchasing [[Essential Mod Bundle]]s from the Market.
*'''[[Daily Tribute]]:''' Logging in for 200/400/600/900 days will award players {{M|Primed Fury}}, {{M|Primed Vigor}}, {{M|Primed Shred}}, and {{M|Primed Sure Footed}}.
*'''In-game vendors.''' Players can purchase mods:
**from [[Syndicates]] with {{sc}} standing. These generally consist of warframe and weapon [[:Category:Augment Mods|Augments]]
**from [[Nightwave]] Cred offerings. These include certain [[Aura]] Mods.
**from [[Baro Ki'Teer]] on a relay for {{cc|Credits}} and {{dc|Ducats}}. These include all of the [[:Category:Primed Mods|Primed]] mods, except for those which are obtained through Daily Tribute.
*'''[[Trading]]:''' All mods are tradeable '''except''' for those which are obtained through Daily Tribute (certain Primed mods), the [[Umbra Mod]]s (obtained via [[The Sacrifice]] quest or from [[Cephalon Simaris]]), [[Flawed Mods]] (obtained via [[Vor's Prize]] quest), and ''[[:Category:Amalgam_Mods|Amalgam mods]]'' (obtained via the [[Thermia Fractures]] event or the [[Ropalolyst]] boss fight).
**Trading recipient of a [[Riven Mods|Riven Mod]] must have attained [[Mastery Rank]] 8.
**Last copy of {{Pol|Penjaga}} Precept polarity mods cannot be traded away.
*Acquiring '''[[Companions]]''' provides the player with a set of precept mods specific to each companion.
*See [[Riven Mods]] page for acquisition of such mods.
*Opening [[Void Relic|Requiem Relics]] have a chance to reward [[Requiem Mods]] except Oull, which has a chance to drop when downing a [[Kuva Lich]] or a [[Sisters of Parvos|Corpus Sister]].
*Completing a [[Conclave]] match may reward a [[:Category:PvP Mods|Conclave mod]].

==Attributes==
[[File:Attributes-information.png|right]]
Mods have several attributes:
#'''Name & Effect:''' The name of the mod and what it changes when installed. The name includes an identifier of the variant (The descriptors "Flawed", "Primed", and "Amalgam"), or set ''("Umbral" in the right image)'', if applicable. 
#'''Item Compatibility:''' What the mod can be equipped on and if it's part of a [[Set_Mods|Mod Set]]. Individual mods are equippable either on any of a more general type of equipment (e.g. “MELEE”), or only on one of a subtype, (e.g. “SWORDS”), or only on a single piece of equipment and its closest variants (e.g. “SKANA”), or only exclusively on one specific variant (e.g. “BURSTON PRIME”).
#'''Special Indicator:''' Symbols that denote if the mod is an [[Aura]], [[Stance]], [[Exilus]], [[Riven_Mods|Riven]] or part of a Set.
#'''Drain & Polarity:''' The number is the amount of Capacity points a mod uses up when installed ("drain", except [[Aura]]/[[Stance]] mods that "provide" Capacity points instead). The symbol denotes [[Polarity]] ''(described further below)''.
#'''Rank:''' The upgrade level of the mod, ranging from rank 0 to Maximum Rank, which varies according to mod, the highest being 10. When the level of a mod is greater than zero, it is indicated by blue pips on the bottom of the card.'' (A small black hexagon appears above the rank pips on mods that are slotted – not visible in the right image.)''
#'''Stack/Quantity:''' The quantity of a mod of the same rank that you own.
#'''Rarity:''' Determines the order of appearance of mods when sorted by rarity in the mod inventory view, and will also be printed in the [[trading]] confirmation prefixing mod's rank (e.g. “RARE RANK 5” or “REQUIEM RANK 0”). Mods vary in 9 tiers of rarity, with higher tier rarity mods displayed earlier (more to the left) in the sorting order.

*For mods of the lowest 4 tiers (Common-Legendary), their rarity defines both increasing with rarity applicable [[Endo|fusion]] costs and [[trading]] taxes (being highest for Legendary out of all mods in game), while the 5 highest tiers (Riven-Requiem) share these with Rare mods (except Peculiar - sharing with Uncommon instead).
*Most mods of the lowest 5 tiers have an increasing number of pips at the top of their mod cards ''(except mods that are part of a Set - such as the image to the right - displaying the Set emblem in place of pips)''. In the order of increasing rarity these are:

===Hidden Attributes===
*Some mods have <code>CompatibilityTags</code> and <code>IncompatibilityTags</code> associated that restrict what items that it can be equipped on.
**For example, {{M|Sinister Reach}} has both the "Primary" type and a hidden <code>BEAM</code> compatibility tag, restricting its usage to primary weapons with that tag (like {{Weapon|Amprex}} and {{Weapon|Phantasma}}).
**For example, the {{M|Split Flights}} mod has the following <code>IncompatibilityTags</code>: <code>CRPBOW, CROSSBOW, GRNBOW, POWER_WEAPON, INFBOW, OMICRUS</code>, meaning items with either of those tags (namely, {{Weapon|Lenz}}, {{Weapon|Kuva Bramma}}, [[Exalted Weapon]]s, {{Weapon|Proboscis Cernos}}, and {{Weapon|Nataruk}}) cannot equip {{M|Split Flights}}.
*Some mods may have hidden upgrades not explicitly stated in the mod's description. Notable examples include:
**{{M|Heavy Caliber}}, {{M|Magnum Force}}, and {{M|Vicious Spread}} with additional hidden spread modifiers for specific weapons.
**{{M|Sure Footed}} and {{M|Primed Sure Footed}} include chances to ignore staggers, stuns, and ragdoll effects.
**{{M|Cunning Drift}}, {{M|Maglev}}, and {{M|Streamlined Form}} apply a hidden slide penalty when player is in mid-air to counteract the slide bonus (i.e. player only gets increased slide distance on ground).
**{{M|Thundermiter}} also decreases Ammo Maximum despite not saying so in description.
*Two mods with the same hidden parent type or has a [[wikipedia:Inheritance (object-oriented programming)|parent/child relationship]] cannot both be equipped on an item at the same time. For example, {{M|Serration}} and {{M|Amalgam Serration}} are incompatible with each other because they both inherit the <code>/Lotus/Types/Game/LotusArtifactUpgrades/BaseArtifactUpgrade</code> type. Sometimes this relationship is obvious because two mods share similar names, but this is not always the case (for example, {{M|Sinister Reach}} is not a variant of {{M|Reach}} despite both having "Reach" in their names). Some non-obvious relationships include:
**{{M|Mobilize}}, {{M|Patagium}}, {{M|Battering Maneuver}}, {{M|Piercing Step}}, {{M|Rending Turn}}, {{M|Ice Spring}}, {{M|Lightning Dash}}, and {{M|Toxic Flight}} are incompatible with each other since they all inherit <code>/Lotus/Upgrades/Mods/Warframe/ParkourTwoMod</code>.
**{{M|Ironclad Flight}} inherits <code>/Lotus/Upgrades/Mods/Warframe/AvatarDamageReductionInAir</code> ({{M|Aviator}}).
**{{M|Critical Deceleration}} inherits <code>/Lotus/Upgrades/Mods/Shotgun/WeaponCritChanceMod</code> ({{M|Blunderbuss}}).
**{{M|Berserker Fury}} inherits <code>/Lotus/Upgrades/Mods/Melee/WeaponFireRateMod</code> ({{M|Fury}}).
**{{M|Enhanced Vitality}} inherit {{M|Link Vitality}} <code>/Lotus/Upgrades/Mods/BaseHealthMod</code>.
**{{M|Link Fiber}} and {{M|Metal Fiber}} inherit <code>/Lotus/Upgrades/Mods/BaseArmourMod</code>.
**{{M|Calculated Redirection}} and {{M|Link Redirection}} inherit <code>/Lotus/Upgrades/Mods/BaseShieldMaxMod</code>.
**{{M|Mending Shot}} inherits <code>/Lotus/Upgrades/Mods/Rifle/BowExplosionChanceMod</code> ({{M|Thunderbolt}}).
**{{M|Amar's Anguish}}, {{M|Boreal's Anguish}}, and {{M|Nira's Anguish}} inherit <code>/Lotus/Upgrades/Mods/Sets/ArchonExilusMod</code>.
**{{M|Amar's Hatred}}, {{M|Boreal's Hatred}}, and {{M|Nira's Hatred}} inherit <code>/Lotus/Upgrades/Mods/Sets/ArchonWarframeMod</code>.
**{{M|Double Tap}} inherits <code>/Lotus/Upgrades/Mods/PvPMods/Rifle/LessRecoilSmallerMagRifleMod</code> ({{M|Hydraulic Gauge}}).
**{{M|Feathered Arrows}} inherits <code>/Lotus/Upgrades/Mods/PvPMods/Rifle/HigherVelocityLessAccurateRifleMod</code> ({{M|Lucky Shot}}).
**Conclave physical damage conversion mods:
***{{M|Comet Rounds}}, {{M|Ripper Rounds}}, and {{M|Serrated Rounds}} inherit <code>/Lotus/Upgrades/Mods/PvPMods/Rifle/BaseDamageBiasRifleMod</code>.
***{{M|Impaler Munitions}}, {{M|Meteor Munitions}}, {{M|Razor Munitions}} inherit <code>/Lotus/Upgrades/Mods/PvPMods/Pistol/BaseDamageBiasPistolMod</code>.
**Conclave recoil/reload/magazine balancing mods:
***{{M|Hydraulic Chamber}} inherits <code>/Lotus/Upgrades/Mods/PvPMods/Shotgun/FasterReloadMoreRecoilShotgunMod</code> ({{M|Loose Chamber}}). {{M|Loose Chamber}} inherits <code>/Lotus/Upgrades/Mods/PvPMods/Shotgun/LargerMagLongerReloadShotgunMod</code> ({{M|Loaded Capacity}}).
**Warframe augments on the same ability:
***{{M|Rumbled}} and {{M|Titanic Rumbler}} inherit <code>/Lotus/Powersuits/Brawler/BrawlerSummonBaseAugmentCard</code>.
***{{M|Healing Flame}} and {{M|Purifying Flames}} inherit <code>/Lotus/Powersuits/Ember/FireBlastBaseAugmentCard</code>.
***{{M|Purging Slash}} and {{M|Surging Dash}} inherit <code>/Lotus/Powersuits/Excalibur/SlashDashBaseAugmentCard</code>.
***{{M|Assimilate}} and {{M|Singularity}} inherit <code>/Lotus/Powersuits/Jade/SelfBulletAttractorBaseAugmentCard</code>.
*Most mods will not be obtainable through [[Transmutation]]. Internally, there is a property associated with the mod that determines its transmutability status.
*[[Stance]] mods will add new attack combos to [[Melee]] weapons which are not explained in fully in the mod's description or combo menu upon equipping the Stance. Many Stance combos have hidden damage multipliers and guaranteed status effects on its attacks.

==Interaction==
Multiple specialized UI environments exist to facilitate players' various interactions with mods:
*'''Arsenal''' (used for '''installing''' all mods, except for Railjack mods)
*'''Plexus''' (used for installing Railjack mods)
*'''Mods Console''' (used for managing owned mods through '''Mod Actions''': ''"Fusion"'', ''"Transmute"'', ''"Sell"'', and ''"Dissolve"'')
*'''Codex''' (used for '''obtaining knowledge''' on all existing mods, and ways to acquire them)
*'''Trade screen''' (used for exchanges with other players involving mods)

Introduced in {{ver|12}}, mods of the same type and fusion level are placed into an item stack, with a number on the top left showing how many of that item is available. This process is essential in reducing clutter and is also used to ease the process of selling or dissolving mods.

===Installation===
Once the Mods system has been unlocked, mods can be installed by visiting the [[Arsenal]] on your [[Orbiter]], selecting the desired Mod destination (e.g. [[Warframe]], [[Weapon]]), and then clicking on the {{Key|UPGRADE}} button. Afterward either click on {{Key|ACTIONS}} > {{Key|APPLY AUTO INSTALLATION}}, or simply drag a mod from the collection and drop it on a Mod slot. Mod installation and removal is instant and free.

Mods are placed in '''Mod Slots''' (commonly referred to as "slots"), arrayed in a rectangular grid. In addition to these '''general slots''', which are compatible with the vast majority of mods, some types of equipment have '''special slots''', which are only compatible with a corresponding class of mods.

{| align="right" width=30% style="text-align:center;"
|+ '''Mod priority order<br />(for Companion Precepts and Elemental [[Damage]] mods)'''

|-
| style="background:#00000040;" | 5 || 6 || style="background:#00000040;" | 7 || 8
|}

The number and type of slots an item will have depends on the type of equipment:
*[[Warframes]] have 8 general slots, an Exilus slot, and an Aura slot.
*Primary and secondary weapons have 8 general slots and an Exilus slot.
*[[Melee|Melee weapons]] have 8 general slots, an Exilus slot, and a Stance slot.
*[[Archgun]]s, [[Archmelee]]s, and Companion weapons have 8 general slots.
*[[Exalted Weapon|Exalted weapons]] have 8 general slots; Melee Exalted weapons also have a Stance slot, but it's permanently occupied by an Ability-related Stance, and can't be interacted with.
*[[Companion]]s have 10 general slots. 
*[[Archwing]]s and [[K-Drive]]s have 8 general slots.
*[[Necramech]]s have 12 general slots.
*[[Plexus]] (the [[Railjack]] modding system) has 8 general slots and an Aura slot on one grid (Integrated), and 3 special slots on each of the other two grids (Battle and Tactical).  

Items have a limited '''Mod Capacity''', that correlates to their Rank. The maximum rank is normally '''30''', but for some items it is '''40'''. Warframes/Companions/Archwings/K-Drives/Necramechs and Weapons can be supercharged with an [[Orokin Reactor]] or [[Orokin Catalyst]] respectively, which doubles the available Mod capacity. Mod Capacity functions as a limit to what mods can be equipped depending on their drain. Mods can have a '''drain''' of 0 to as high as 20 depending on the mod and what rank it is. Items also have a minimum mod capacity, which adds mod points onto items that are a lower rank than a player's current [[Mastery Rank]]. The amount of minimum mod capacity is equal to the player's mastery rank.

If the Mod Capacity drain is less or equal to the item’s remaining Mod Capacity it will install and Mod Capacity will be deducted. 

Mod drain is modified by [[Polarity]]:
*Matching [[Polarity|polarity]] reduces drain by half, rounded up: (e.g. {{M|Serration}} costs 14, but dropped into a {{Pol|Madurai}}Madurai polarized slot costs only 7)
*Non-matching [[Polarity|polarity]] increases drain by a quarter, rounded mathematically: drain of 0-1 will increase by 0, drain of 2-5 by 1, drain of 6-9 by 2, drain of 10-13 by 3, drain 14-16 by 4, etc.

[[Aura]] and [[Stance]] mods increase Mod Capacity rather than drain it.
*Polarity affects the amount of bonus Capacity that is provided: matching polarity doubles it, while non-matching polarity reduces it by 25%, rounded mathematically.

The [[Railjack]] analogue of the Arsenal is the [[Plexus]], also located in the Orbiter, and accessible from a Dry Dock.

===Fusion===
{{Main|Fusion}}
Mods can have their overall power increased by the process called '''Fusion'''. Fusing a mod with [[Endo]] increases the rank, and thereby overall power, of the mod. While the base amount of Endo required to level up from rank 0 to rank 1 is determined by Mods' rarity, each subsequent rank-up requires twice the Endo amounts from the previous rank-up (e.g. Leveling a common mod from rank 0 to rank 1 requires 10 Endo, from rank 1 to rank 2 requires 20, from rank 2 to rank 3 require 40, and so forth).

===Transmutation===
{{Main|Transmutation}}
Transmutation is one of the ways of acquiring mods. Choosing this Mod Action, players can sacrifice four selected unranked mods to generate a random mod from a list of mods that can be acquired in this way. Alternatively, three selected mods and one  {{M|Vazarin Transmute Core|Transmutation Core}} can be used to guarantee a random mod of a specific [[Polarity|polarity]]. Transmutation of [[Riven Mods]] requires a [[Riven Transmuter]]. Mods that cannot be acquired by transmutation are conventionally called '''untransmutable mods'''.

===Selling===
Choosing this Mod Action, a player can convert a mod into an amount of {{Resource|Credits}} equal to '''75%''' of the Credits invested in the mod<ref name="spreadsheet">[https://docs.google.com/spreadsheets/d/1izlOGPEPJpBMuubP7g3hD78JpJQQsEBX1d-Ox_u6ZkA Google Sheet w/ Mod Sell Price, Mod Endo Dissolution, and Avionic Dirac scrap calculations]</ref>. Any selection of single mods and/or stacks of mods can be sold, and players are prompted to review and confirm the action after clicking ''"Sell"'' (after a mod has been "sold" this way, it isn't physically found anywhere – it has been eliminated). Notably, [[Riven Mods]] cannot be sold.

==Standard Mods and Variants==
{{For|information on calculating bonuses from mods|Calculating Bonuses}}

Standard mods (or '''single-stat mods''') are the basic '''class of mods''': all the mods that provide a straightforward bonus to a single stat. In each item category, each base stat only corresponds to one standard mod. At times, changes to game mechanics have included total redesigns of some mods to become a different single-stat mod or dual-stat mods (e.g. {{M|Quickening}}), but these are still essentially standard mods. Standard mods are generally equipped in one of the main slots, but some are [[Exilus]] mods.

A standard mod may come in six variants: '''Normal''', '''Flawed''', '''Primed''', '''Umbra''', '''Amalgam''', '''Galvanized''', and '''Archon'''. In addition to being eligible for these variants, standard mods may also have a unique variant.

Rarity only somewhat corresponds to classes of mods: some standard mods are Rare, and some nonstandard mods are Common. 

Players '''cannot''' install duplicate mods onto a single piece of equipment. Likewise, different variants of the same mod '''cannot''' be equipped together. For example, a given pistol can only accept one {{M|Hornet Strike}} mod at a time, and {{M|Flow}}, {{M|Primed Flow}} and{{M|Archon Flow}} can't be installed together on a single Warframe.

{| class="wikitable"
|-
! Variant !! Description !! Example
|-
| Normal
| Normal mods are mods that lack a property that would distinguish them as Flawed/Primed/Amalgam/Galvanized. This is the base variant and has a generic appearance. 
Normal standard mods generally drop from regular enemies, and are the most easily obtainable mods. They are transmutable, sellable and tradeable.
| {{M|Serration}}
|-
| Flawed
| {{Main|Flawed Mods}}
Flawed mods are an '''inferior variant''' of standard mods. They have a maximum rank of 3, and provide an overall reduced effect. They are automatically picked up during the course of the [[Vor's Prize]] quest. Flawed mods are untransmutable and untradeable. The quest in which are they are obtained is not replayable, so there is no way to gain additional Flawed mods subsequent to it. Visually, Flawed mods have a cracked image.
| {{M|Flawed Serration}}
|-
| Primed
| {{Main|:Category:Primed Mods}}
Primed mods are a '''superior variant''' of mods, that have had their maximum rank increased to 10. Most Primed mods can be obtained from [[Baro Ki'Teer]], but four Primed mods, {{M|Primed Fury}}, {{M|Primed Vigor}}, {{M|Primed Shred}}, and {{m|Primed Sure Footed}} are only obtained from 200/400/600/900 [[Daily Tribute]]s and cannot be traded with players. All Primed mods are of the Legendary rarity, and they are untransmutable.
| {{M|Primed Continuity}}
|-
| Umbra
| {{Main|Umbra Mod}}
Umbra mods are a class of Legendary mods, that feature the properties of both Primed mods and [[Set Mods]]. All are a '''superior variant''' of a standard mod, while also possessing a '''second stat''' that grants enhanced effectiveness when fighting [[Sentient]] enemies. They are divided in sets, but the Set Bonus of each set is the same: an increase of each mod's bonuses. Umbra mods are acquired through the [[The Sacrifice]] [[Quest]] (and can thereafter be reacquired via [[Cephalon Simaris]]). They are untransmutable and untradeable. All Umbra mods have the exclusive {{Pol|Umbra}}Umbra polarity that can only be applied with an [[Umbra Forma]]. Visually, Umbra mods are Legendary mods with a set indicator. 
| {{M|Sacrificial Pressure}}
|-
| Amalgam
|{{Main|:Category:Amalgam Mods}}
Amalgam mods can be either slightly inferior or superior variants, and come with certain '''additional properties'''. Some sacrifice a small amount of their main bonus to provide a small bonus ''to another stat of an altogether different item''. Others are weapon-specific, and are actually superior variants, while still having a second stat. The latter also usually have a third stat, generally understood as a novelty/utility feature (e.g. extra gore). Amalgam mods do not have a formal Rarity tier, but yield the same amount of Credits and Endo when sold and dissolved, respectively, as Rare mods. They are untransmutable and untradeable. Thematically, they are amalgamations of two existing mods (so for example, {{M|Amalgam Serration}} can be seen as a combination of {{M|Serration}} and {{M|Rush}}). These mods have a distinct Sentient-influenced visual styling. 
| {{M|Amalgam Serration}}
|-
| Galvanized
|{{Main|:Category:Galvanized Mods}}
Galvanized mods have slightly inferior base stats than their original counterpart, but in turn have stacking buffs from killing enemies that make them a '''superior variant''' to standard mods. Their maximum ranks are increased to 10. Galvanized mods do not have a formal Rarity tier, but yield the same amount of Credits and Endo when sold and dissolved, respectively, as Rare mods. Galvanized mods are purchased from the [[Arbitrations]] vendor for 20 [[Vitus Essence]] each.
| {{M|Galvanized Diffusion}}
|-
| Archon
|{{Main|:Category:Archon Mods}}
Introduced in [[Veilbreaker]], Archon mods are a special variant of Warframe mods that trigger special effects '''upon using Warframe Abilities that satisfy conditions''' such as killing an enemy with a particular element, causing an elemental proc, or healing. All currently existing Archon mods have a max rank of 10 and have rank up costs similar to Legendary mods. Archon mods are purchased using [[Stock]] from [[Chipper]] upon reaching Rank 3 (Fort) with [[Kahl's Garrison]].
| {{M|Archon Stretch}}
|-
|}

==Nonstandard Mods==
Nonstandard mods are all the other mods that provide bonuses to either the same stats as the standard mods or to certain other stats, or modify equipment in specific ways. They come in different classes and have a more varied design. Nonstandard mods '''stack''' with other mods providing the same type of bonus (certain exceptions exist). Therefore, {{M|Vitality}} (a standard [[Health]] mod) stacks with {{M|Vigor}} (a Nightmare mod, providing both a [[Health]] and [[Shield]] bonus). They generally do not have variants (a small number of Primed Nightmare mods are one exception). 

{| class="wikitable"
|-
! Variant !! Description !! Example
|-
| Nightmare
| {{Main|:Category:Nightmare Mode Mods}}
Nightmare Mode Mods (commonly called ''Nightmare mods'') are a class of Rare '''dual-stat mods''' – they provide a bonus to two different stats ''for the same item''. They can be acquired through completing missions in the [[Nightmare Mode]]. Nightmare mods are untransmutable. Visually, they do not have a clearly distinguishing mark. 
| {{M|Shred}}
|-
| Corrupted
| {{Main|:Category:Corrupted Mods}}
Corrupted mods are a class of Rare mods that affect '''one stat positively and another negatively'''. Those available for warframes are characterized by extremely high bonuses balanced by major penalties. Those available for weapons provide bonuses of a similar strength to their standard mod analogues, while still also having a penalty. Corrupted mods can be obtained from the [[Orokin Derelict]], using special [[Dragon Key]]s to unlock vaults located within. They are untransmutable. Visually, they do not have a clearly distinguishing mark.
*Corrupted mods that provide a bonus to [[Critical Chance]] (e.g. {{M|Critical Delay}}) are a notable exception to the general pattern of nonstandard mods in that they can't be stacked with their standard analogues.  
| {{M|Fleeting Expertise}}
|-
| Conditional
| {{Main|:Category:Acolyte Mods}} ''(a subset of conditional mods)''
Conditional mods are mods that '''require some condition to be met during combat''' in order for their effect to activate. A large subset of these mods are called '''[[Acolytes|Acolyte]] mods''', and these now drop in [[Deimos]] [[Bounty|bounties]]; others are dropped in the same manner as standard mods (notably, {{M|Condition Overload}}). Acolyte mods are untransmutable, and the remainder may or may not be. Visually, they do not have a clearly distinguishing mark. 
*{{M|Split Flights}} (a conditional [[Multishot]] mod for Bows) and {{M|Split Chamber}} being mutually exclusive is another notable exception to the general pattern of nonstandard mods' ability to be stacked with standard mods. 
*As a potent illustration of the difference between standard and non-standard mods, {{M|Charged Chamber}} and {{M|Primed Chamber}} ''(note that it is not a Primed mod; "Primed" here simply refers to priming such as that of an explosive charge)'' two conditional Sniper mods, the latter ostensibly a superior variant of the former, '''are''' in fact stackable – following the general pattern of nonstandard mods providing the same type of bonus not being mutually exclusive.  

Many Set mods and some Augments (e.g. {{M|Hata-Satya}}) also have a conditional effect. 
| {{M|Argon Scope}}
|-
| Augment
| {{Main|Warframe Augment Mods}}{{Main|Weapon Augments}}
Augment mods (''commonly called Augments'') provide augmentation to a '''specific Warframe or weapon'''. On warframes, they alter abilities or passives. On weapons, they provide straight up bonuses, sometimes superior to standard mods (e.g. {{M|Scattered Justice}}). Most can be obtained as [[:Category:Syndicate Offerings|Syndicate Offerings]], but a significant number is obtained elsewhere (for example, some are [[:Category:Executioner Mods|Executioner Mods]]). They are untransmutable. Augments granting Syndicate effects are overlaid with their Syndicate logo. 
*Different Augments affecting the same ability or passive cannot be equipped together (e.g. {{M|Aviator}} with {{M|Ironclad Flight}} on {{WF|Titania}}). 
*Single-weapon Amalgam mods (e.g. [[Amalgam Ripkas True Steel]]) should not be confused with Augments. Augments stack with standard mods (therefore ''augmenting'' that which is standardly available), while Amalgam mods do not, as they ''are'' the standard mods themselves, in that particular variant.
| {{M|Smoke Shadow}}
|-
| Riven
| {{Main|Riven Mods}}
Riven Mods provide '''randomized bonuses''' to a '''specific weapon''': up to three bonuses, and a penalty. The bonuses on Rivens tend to be based around standard mods (normal or primed), and these base bonuses are modified by a stat individual to each weapon called disposition. When acquired, Riven Mods come in a veiled form which supplies no stats and must have a challenge completed in order to unveil it. They are transmutable using a [[Riven Transmuter]], and transmutation produces a veiled Riven. The only way to obtain unveiled Riven Mods directly is by trading with players. Riven mods are purple.
| [[File:RivenGrakataMod.png|x100px]]
|-
| Set
| {{Main|Set Mods}}
Set Mods are a class of [[Mods]] that offer increasing bonuses when one or more mods in a set are equipped together in a current loadout. Each mod of a set, apart from it's individual effects, also provides a second '''Set Bonus''' effect shared between all the mods in the set, that becomes stronger the more of the set's mods are installed. Many set mods have conditional effects, and some even figure as dual-stat conditional mods (e.g. {{M|Motus Setup}}). Set mods are untransmutable. They are distinguishable by their shared set prefix (e.g. Augur, Gladiator, Vigilante, etc.) and icon on top of their card.
| {{M|Augur Secrets}}
|-
|}

==Special Slot Mods==
The following types of mods have a special, dedicated slot.

{| class="wikitable"
|-
! Variant !! Description !! Example
|-
| Aura
| {{Main|Aura}}
Aura Mods are Warframe mods that benefit the entire [[Squad]] and also increase the player's Warframe total mod capacity. They can only be equipped in the dedicated Aura slot and only one Aura can be equipped to a Warframe. They can normally be obtained from [[Nightwave]] Cred offerings, but some drop from [[The Silver Grove]] specters and [[Nox]]. They are untransmutable. 
| {{M|Energy Siphon}}
|-
| Stance
| {{Main|Stance}}
Stance mods are special mods for [[:Category:Melee Weapons|Melee Weapons]]. They increase the player's melee weapon mod capacity and unlock unique attack combos. They can only be equipped in the dedicated Stance slot for a specific weapon type and only one Stance can be equipped to a melee weapon. Most Stance mods are transmutable. 
| {{M|Crimson Dervish}}
|-
| Exilus
| {{Main|:Category:Exilus Mods}} ''(Warframes)''
{{Main|:Category:Exilus Weapon Mods}}
Exilus Mods are utility or mobility-based mods that can be equipped in the Exilus slot, or if the player chooses, in a general slot. The Exilus slot is present on all Warframes and primary and secondary weapons; on Warframes, it must be unlocked with an [[Exilus Adapter]], and on weapons, it must be unlocked with an [[Exilus Weapon Adapter]].

Some Exilus mods exist as typical standard mods, e.g. {{M|Sure Footed}} and {{M|Primed Sure Footed}}.

Some Exilus mods exist as somewhat atypical, but also essentially standard, mods:
*A number of mods similar to {{M|Mobilize}} are treated as it's "cognates", meaning that {{M|Mobilize}}, {{M|Patagium}}, {{M|Battering Maneuver}}, {{M|Piercing Step}}, {{M|Rending Turn}}, {{M|Firewalker}}, {{M|Ice Spring}}, {{M|Lightning Dash}}, and {{M|Toxic Flight}} '''do not stack''', in line with the expectation that standard mods with the same type of effect do not stack. Despite these not being single-stat mods in a technical sense, their mobility enhancements are seen as a unified effect.

Many Exilus mods are nonstandard mods, such as the the dual-stat "Drift" mods.
*Consistent with standard and nonstandard mods being able to stack, {{M|Mobilize}} '''stacks''' with {{M|Stealth Drift}}.

Exilus mods have the Exilus mark near the top.
| {{M|Battering Maneuver}}
|-
| Peculiar
| {{Main|:Category:Peculiar Mods}}
Peculiar Mods are a subtype of Exilus mods. They do not offer any mechanical effects at all, instead only causing bizarre cosmetic effects. These mods, despite offering no real benefit to their users, are some of the rarest and most difficult to obtain artifacts in the system. They have a distinct smoky appearance.
| {{M|Peculiar Bloom}}
|-
|}

==Unique Mods==
Mods that do not fit in the above categories:
{| class="wikitable"
|-
! Variant !! Description !! Example
|-
| Precepts
| {{Main|:Category:Penjaga_Mods}}
Precepts are mods which alter the behavior of a [[Companion]], and are effectively the companion's "abilities". Every Companion has their own specific precepts. However, there are precepts that are universal within a class of companions. Upon acquiring a companion, the user is automatically granted some or all of the respective specific precept mods. 

[[File:Precept System Priority.png|right|frame|Priority for precept usage (1 is highest priority and 10 is lowest).]]
Precepts have "informally" designated slots by virtue of having the {{Pol|Penjaga}} Penjaga polarity, exclusive to them, and there being four matching-polarity slots on every companion. Since these are still general mod slots, the player can alter this setup in any number of ways, and Precepts can be installed in other slots as well. Companions will use their precepts in a prioritized order, where the top left slot is the highest priority and the bottom right slot is the lowest. 

Players may not trade away / sell / dissolve a precept if it's their only copy of the mod. 

Visually, Precepts do not have a clearly distinguishing mark (but can be identified in a glance by their polarity).
| {{M|Charm}}
|-
| [[Parazon]]
| {{Main|:Category:Parazon Mods}}
{{Main|Requiem Mods}} ''(subset of Parazon Mods)''
Parazon mods may only be equipped on the [[Parazon]] and grant effects which are tied to the Mercy mechanic and hacking. A type of Parazon mods are Requiem mods, which are used to defeat a Kuva Lich.
| {{M|Intruder}}
|-
| Railjack/Plexus
| {{Main|Plexus}}
Railjack Mods ''(also called Plexus Mods)'' are applied to the [[Railjack]]-modding platfrom called [[Plexus]]. They are divided into three categories: Integrated, Battle, Tactical, each category being compatible with the respective mod grid within the Plexus. Integrated mods provide stat bonuses to the Railjack and it's Armaments, and include Railjack Aura mods. Battle Mods provide the Railjack with energy-based abilities, while Tactical Mods provide the Railjack with cooldown-based abilities. Mods in the latter two categories do not drain capacity, but are further divided into Defensive, Offensive, and Super subcategories, each corresponding to a single special slot. They drop in [[Empyrean]] missions, and are untransmutable. Visually, Railjack Mods can be identified by their molded alloy trim. 
| {{M|Crimson Fugue}}
|-
| Conclave
| {{Main|:Category:PvP Mods}}
Conclave Mods can be mainly acquired from the [[Conclave]] [[Syndicates|Syndicate]], where they originated from. Some of them can also be used in PvE (possibly with altered stats or effects) and can be obtained through [[Nightwave]] Cred offerings, while others are dropped by [[Sentient]]s.
| {{M|Tear Gas}}
|-
|}

==Notes==
*Despite most succinctly described as "upgrades", ''Mods are not the only [[Upgrade|upgrades]]''; in tandem with Mods, a few other forms of upgrades exist: [[Arcane Enhancement]]s (another type of extrinsic upgrades, not too dissimilar from Mods), [[:Category:Arcane Helmet|Arcane Helmets]] (a legacy alternative to an Arcane Enhancement), [[Valence Fusion]] (a way to upgrade base stats of certain items), [[Focus]], and [[Intrinsics]] (permanent intrinsic upgrades to the [[Operator]] and the [[Railjack]], respectively; they also affect certain other equipment, to a lesser degree).
*For mods increasing shield, health, or energy, bonuses are calculated from a warframe's base value and '''stack additively with the [[Warframes#Leveling Up|Rank Bonuses]]'''. This prevents exponential increases with the passive leveling bonuses introduced in {{ver|7.6}}.
*Mods dropped on the ground will display a visual effect where white specks of energy converge on its position, making the mod more visible. If two or more players are in a mission, this visual effect will remain in place as long as any player has not collected the mod, and will only disappear if all players have picked up the mod. The visual effect itself can be marked using a [[waypoint]] to inform other players where the mod is, even if the player placing the waypoint has already picked up the mod. Waypointing a mod will also display its name even if a player hasn't picked it up.
**Rare mods project a stronger, yellow-gold effect with a clear column of golden energy projecting into the air. Similarly, the orbs for components and blueprints dropped by special enemies create a distinctive purple energy column. Mods dropped by enemies in [[Rathuum]] and [[The Index]] display a projection of red energy.
*Although thematically anachronistic (since they do not drop from Acolytes anymore), the designation of certain mods as Acolyte mods is not entirely obsolete insofar [[Exalted Weapon]]s cannot receive Acolyte Mods, while they can generally receive other conditional mods.
**Further distinguishing Acolyte mods as a formal class of mods, there is a single non-conditional Acolyte mod: {{M|Body Count}}; it also cannot be slotted in Exalted Weapons.
<!-- **''In all other respects there is nothing mechanically special about Acolyte mods, that would merit their separation from conditional mods in general'' -->

==Trivia==
*There are around '''{{#invoke:Mods|getModCount|rarity=All}}''' mods existing in the game including [[Flawed Mods|Flawed]] variants but excluding unveiled [[Riven Mods]]. This count includes:
**'''{{#invoke:Mods|getModCount|rarity=Common}}''' Common
**'''{{#invoke:Mods|getModCount|rarity=Uncommon}}''' Uncommon
***'''3''' Peculiar
**'''{{#invoke:Mods|getModCount|rarity=Rare}}''' Rare
***'''9''' Amalgam
***'''9''' Requiem
***'''8''' Riven (veiled)
***'''9''' Galvanized
***'''8''' Tome
***'''5''' unique stance mods exclusive to certain [[Exalted Weapon]]s
**'''{{#invoke:Mods|getModCount|rarity=Legendary}}''' Legendary
***'''5''' Archon
**The unobtainable [[Fusion Core]] and [[Ancient Fusion Core]]s
*Some older mods still use legacy images that no longer apply to the current build of the game, usually with enemies using weapons that they no longer use, or they are used by an enemy that no longer wields that weapon.
**This includes {{M|Point Blank}} and {{M|Hell's Chamber}} where a [[Lancer]] is using a {{Weapon|Braton}}; {{M|Corrosive Projection}} where a [[Shield Lancer]] is using a {{Weapon|Sicarus}} and so on. (feel free to list more)
**Another instance is a mod like {{M|Antitoxin}} which still includes the image of a legacy version [[Toxic Ancient]], back when Infested Ancients used to be large mutated Crewmen instead.
*Stat values displayed on a mod card are sometimes rounded to the nearest tenth place. This is rarely seen in mods like {{M|Reach}} and {{M|Primed Reach}} when the maximum effect number is not divisible by the number of mod ranks.
**However, duration values are rounded to the nearest integer. This is seen in mods such as {{M|Triple Tap}} where a temporary buff is applied after meeting certain conditions.
*Prior to {{ver|The Silver Grove}}, all mods and equipment had a special [[Conclave]] Score to limit loadout configurations by having more powerful mods have a higher Conclave Score. Since the rework to Conclave in {{ver|16}}, this feature had no use. It has since been removed from every equipment and mod.
*After {{ver|16}}, when {{D|Cold}} based mods like {{M|Cryo Rounds}} increased their mod drain to 11, up from 9, builds who had those mods equipped and had 0 remaining mod capacity will show a negative capacity, such as -1 as it flashes red. Players are allowed to keep these builds as is, but removing any of the mods will correct the issue and not allow the player to replace the mod again.

==Patch History==
{{Scrollbox/Article|
{{ver|35.5}}
;Upgrade Screen Changes
*Dragging Mods will now provide more visual information in the Upgrade Screen: 
**Dragging a Mod will now maintain the same aspect ratio as an “open” Mod but scaled down, so that you can still identify it, its Polarity, and its Capacity Cost when moving it across the screen. 
**Slots with matching Polarities to the dragged Mod are now highlighted in green and have a slight pulsing effect to indicate that they are eligible. Slots with mismatched Polarities are highlighted in red.
**Hovering a Mod over a slot will now show how its capacity cost will be affected based on their Polarities. 
*Made it more obvious that Damage Type stats are affected when swapping a Weapon or Modding one. Now, when you are making changes, the Damage types that are negatively impacted will shuffle lower in the list and appear slightly transparent, so that it's easier to spot the changes between comparisons.  

;General UI Changes&#58;
*Added Mod tooltips (hovering over Mods with bold words in their description) for the following terms: 
**Knockdown: Enemies fall to the ground, opening them up to melee ground finishers.
**Sleep: Enemies become unable to perform actions and open to melee finishers.
**Disarm: Disarmed enemies lose their firearms and can only engage in melee combat.
**Lifted: Certain melee attacks can lift enemies into the air, making them temporarily incapable of attacking you.

;GENERAL FIXES
*Fixed artifacting issues on the Mod cards in the UI.

{{ver|35.0.2}}
*Fixed several script errors when Ranking up a Mod.

{{ver|35}}
*Added on-hover tooltips to Mods with unique effects. Mods with a special mechanic will now appear bolded in its description indicating that you can hover over it to learn more about it. This applies to the following (not exhaustive):
**Syndicate Mods (Justice, Truth, Entropy, Blight, Purity, Sequence)
**The new Tennokai Mods
**Mods that grant Overguard

{{ver|34}}
*Adjusted Auto-Install prioritization based on new Warframe Health and Shield values, as well as checking for Shield Recharge Delay.

{{ver|33.5.5}}
*Fixed negative Mod capacity displaying negative number in Arsenal after selling/trading an equipped Aura Mod. 
**''A pop-up will now appear when attempting to sell/trade an equipped Aura Mod, informing players where the Mod is equipped so that it may be unequipped to sell/trade.''

{{ver|33.5}}
;AUTO INSTALL OVERHAUL

We’ve made a number of changes to how the Auto Install function works when Modding Warframes and weapons! Don’t expect this button to replace the need for careful Modding in high level content, but it should result in more consistently useful builds offering positive stats, especially for newer players.

Part of this process includes the following changes:
*Overhauled which stats are prioritized on which weapon types. 
*Mods with universal benefits (like increased damage and multishot) are equipped first, while attempting to equip mods that benefit the weapon type (like critical and status increases) if the base stats are high enough.
*Made Auto Install consider equipping unveiled Riven Mods depending on their stats.
*Made Warframe Aura selection use its own prioritization system when choosing what to install.
*Other Auto Install Fixes:
**Fixed an issue where Auto Install tried to equip veiled Riven mods if there was space.
**Fixed Auto Install prioritizing “conditional” mods that only triggered under special circumstances.

{{ver|32.2.9}}
*Fixed certain Mods stats having randomly long decimals.

{{ver|32.2.5}}
*Removed the Arsenal and Mods consoles in the Relay Drydock. 
**''This was causing multiple issues, and was unnecessary since the Arsenal and Mods can be accessed via pause menu.''

{{ver|32.1}}
*Made changes to the Auto Install Mods logic on Warframes:
**Auto Install valued survivability like health, shields and armor far above all else. These changes value “Ability” stats like Duration and Range just below survivability, choosing Mods like Stretch just after Vitality and Redirection.
**Also added value to certain beginner QOL Mods, for players that don’t have base Ability stat Mods yet.

{{ver|32.0.3}}
*Fixed mod config chat links appearing incorrectly in the condensed link window while using controller.

{{ver|32}}
*The Modding Menu now shows relevant currencies to the Mod you are working on in the currency bar rather than the top corner for the Modding Menu.

{{ver|31.1.3}}
*Fixed chat linked Railjack mods dioramas having unnecessary description text next to the mod.

{{ver|31.1}}
*Fixed being able to hit negative Modding capacity after hitting the cap and then upgrading an equipped Mod beyond capacity as a Mastery Rank Legendary 1 player.

{{ver|31.0.9}}
*Fixed rare case of Mod Capacity going into a negative state when Upgrading Mods when you are over MR 30.

{{ver|30.5}}
*Fixed mod flickering up and down when attempting to upgrade it at the mod segment.
*Added Galvanized mods

{{ver|30.3.4}}
*Fixed Modding discrepancies when moving a Polarity matching Mod and not having enough Mod capacity.

{{ver|30.2}}
*Fixed rare cases of acquired Mods being cut off in the UI.

{{ver|29.6.8}}
*Added a confirmation prompt when selecting to ‘REMOVE ALL’ Mods in the Upgrade screen to alleviate accidental removals.

;Starting Mod Capacity Changes

The starting Mod Capacity for your gear (new or Forma'd) is now determined by your Mastery Rank and if an item has an Orokin Reactor or Catalyst installed.

For example, a Mastery 20 player would experience the following:
#Claim a new Warframe from the Foundry with no Reactor installed.
#Observe the 'Unranked' item and see the starting Mod capacity is 20.
#Install a Reactor, observe the Mod capacity has doubled to 40. 

The formula is: Starting Mod Capacity &#61; Mastery Rank (x2 if Orokin Reactor/Catalyst installed)

The cap on capacity remains unchanged.

Please note this is a slight deviation of our discussions on how Mastery Rank will reflect gear level, but by affecting capacity it fundamentally enables you to use Mods the moment you get your hands on new gear or Forma an item. Have fun!

{{ver|18.12}}
*Warframe Mod text descriptions are receiving a visual overhaul! All Mod descriptions are being manually audited by our team to reflect appropriate status icons and uniform text case. Our goal is to bring consistency to all Mods, and so far almost every Mod has been updated to this format! We ask that you be patient with this change as we comb through Warframe’s extensive Mod collection. This change is purely visual to reduce overly verbose descriptions and discrepancy, and does not affect the functionality of these Mods in any way.

{{ver|15.1.3}}
