 For the melee mod, see Condition Overload.
Condition Overloadtype damage bonuses are a category of bonuses that are activated on transient enemy conditions, such as a Status Effect which can sometimes be applied, as opposed to an enemy faction which is always applied. The current form of CO bonuses were introduced when the mod Condition Overload went through an iteration^{[1]} to make it additive with Pressure Point instead of an exponentiallyscaling multiplier. Today, this same bonus is applicable to almost every weapon class, sometimes by multiple sources, but each source is categorically consistent.
 Community Terminology
 CO (Condition Overload abbreviated. Used in this article to refer to the Condition Overload Mechanic)
 GunCO (Condition Overload for ranged weapons, e.g. primary and secondaries, abbreviated)
 Writer(s) Notes
While much of this page may be considered and acknowledged by developers as bugs, this page exists to reflect the present state of the mechanic, as it has existed for multiple years, not been modified for a year, and becomes more relevant as the mechanics are utilized more by developers despite their state.

Sources of Condition OverloadStyle Bonuses[]
Although some sources are not related to status effects on targets, they are still based on transient conditions and are internally considered the same effect that will additively stack with each other in the list.
 Condition Overload (Melee, +80% per status)
 Galvanized Aptitude (Rifle, +40% per status, stacking up to 2 times for +80% per status)
 Galvanized Shot (Pistol, +40% per status, stacking up to 3 times for +120% per status)
 Galvanized Savvy (Shotgun, +40% per status, stacking up to 2 times for +80% per status)
 Secondary Shiver (Pistol, +45% per Freeze stack)
 Cedo (+60% per status)
 Dual Toxocyst Incarnon Genesis (+33% per status  Evolution 2, Perk 1: Carnage Reign)
 Latron Incarnon Genesis (+30% per status  Evolution 2, Perk 2: Swift Punishment)
 Angstrum Incarnon Genesis (+40% per status  Evolution 4, Perk 3: Fatal Affliction)
 Despair Incarnon Genesis (+40% per status  Evolution 2, Perk 1: Fatal Affliction)
 Zylok Incarnon Genesis (+40% per status  Evolution 4, Perk 3: Fatal Affliction)
 Soma Incarnon Genesis (+40% per status  Evolution 4, Perk 2: Fatal Affliction)
 Kunai Incarnon Genesis (+100% vs <50% health  Evolution 2, Perk 1: Swift Conclusion)
 Dread Incarnon Genesis (+100% vs <50% health  Evolution 2, Perk 1: Hitman's Opportunity)
 Shattering Frost decree (+80% vs Frozen, upgradeable to +240%. Likely affects some abilities.)
For example, Shiver would additively stack with Galvanized Shot, and Dread's lowHP Incarnon bonus would additively stack with the Shattering Frost decree.
Catalyze is not part of the category, as it breaks multiple rules such as being exponential per condition like the original preUpdate 26.0 (20191031) Condition Overload mod, and is a radial attack.
Mechanics[]
Ingame, this bonus is commonly written as "+X% Direct Damage" in the EN localization.
"Direct Damage" is intended language^{[2]} to specify that Radial Explosion Damage does not benefit from CO, but this is not completely true. Despite the spirit of this exclusion, many other forms of crowd damage still benefit.
 The following forms of damage apply CO:
 Hitscan  (e.g., Braton)
 Hitscan Explosion  (e.g., Trumna Main Fire) only on directlyhit target.
 Hitscan Ricochet  (e.g., Lato Incarnon Form)
 Projectiles  (e.g., Boltor)
 Seeking  (e.g., Zymos Spores)
 Bouncing  (e.g., Cyanex)
 Punching Through  (e.g., Lanka)
 Wave Projectile  (e.g., Arca Plasmor)
 Embedded Cloud  (e.g., Pox) only on directlyembedded target.
 Beam  (e.g., Spectra)
 Multibeam  (e.g., Ocucor)
 Beam Chain  (e.g., Kuva Nukor)
 Electricity and Gas procs are generated based on the bonus to the initial target, but carry that proc damage to their radius.
 Forms that do not apply CO are:
 Explosion Radius  (e.g., Ogris)
 Hitscan Explosion Radius  (e.g., Ambassador Altfire)
 Embedded Cloud Radius  (e.g., Torid Mainfire)
 Beam AoE  (e.g., Glaxion Vandal)
 Things that should work but don't:
 Balefire Charger (Has no directhit damage)
 Stug (Despite embeds, is entirely "radial" damage)
 Ferroxseries embedded altfire (Pulsing radius with 2s intervals instead of 1s)
 Azima turret (Should qualify as Hitscan. but not affected)
 Sonicor (Should qualify as wave, but not affected)
 Artemis Bow (Inexplicable)
Application Behaviors[]
COtype bonuses have five known ways of applying, which varies on an attacktoattack basis that is community documented. Say we have a CObonus value of X, ranking CObonus behavior by effectiveness in the eyes of a WARFRAME player:
Ranking/Behavior #  Ranking Description  COBonus Damage Stacking Behavior^{[3]}  COBonus Application Behavior^{[4]}  Player's Metagame Perspective  Attack Examples 

1  CObonus performs extremely better than expected ("excellent")  Multiplicative Stacking ("not intended")  Applies above X% of damage value despite listed as +X% ("not intended")  "Game is bugged in our favor because it multiplicatively stacks with additive stacking bonuses like Serration. Put both CObonus and Serration in the same mod config for this weapon." 
Most projectilebased weapons/attacks

2  CObonus performs better than expected ("good")  Additive Stacking ("intended")  Applies above X% of damage value as listed +X% ("not intended")  "The game is bugged and GunCO provides more damage bonus than its description. Replace additive bonuses like Serration." 
Child projectiles that spawn from a parent projectile (CObonus uses parent projectile damage, which tend to be higher than its children):

3  CObonus performs as expected ("intended")  Additive Stacking ("intended")  Applies exactly X% of damage value as listed +X% ("intended")  "Replace additive bonuses like Serration because CObonus tends to give a larger bonus. Since CObonus and other damage bonuses are additive to each other, I rather use that mod slot for something that increases my damage more like crit damage bonus." (opportunity cost)  Most, if not all, hitscan weapons/attacks and some projectilebased weapons/attacks that behave "normally" 
4  CObonus performs worse than expected ("bad")  Additive Stacking ("intended")  Applies below X% of damage value despite listed as +X% ("not intended")  "Keep using additive bonuses like Serration because CObonus is lying to the player and gives less damage than expected over Serration." 
Most bows' and projectilebased weapons with Charge Trigger Type's Charged Shot

5  CObonus doesn't work ("very bad")  N/A  Does not apply any damage bonus ("intended" or "not intended", depends)  "Keep using additive bonuses like Serration because GunCo doesn't work on this weapon."  Artemis Bow, AoE component of attacks for GunCo bonuses 
Math[]
We can group the behaviors from the previous section into two categories based on how they stack with other damage bonuses:
 Behavior #1: "Multiplying". A multiplicative bonus that additively stacks with only COlike damage bonuses (e.g. Galvanized Aptitude) AND multiplicatively stacks with other damage bonuses (e.g. Serration, Vex Armor, Arcane Fury). Its functionality is reliable and compatible with all weapon bonuses. This is the least common way on how COlike effects stack with damage bonuses.
 Base Weapon Damage × Most Damage Bonuses × CO × Other Damage Multipliers
 Example with Serration and 2 procs/1 stack of Galvanized Aptitude bonus:
 Behavior #2/3/4: "Adding". A multiplicative bonus that additively stacks with ALL +% Damage mods, damage bonuses, AND COlike damage bonuses (e.g. Serration, Vex Armor, Arcane Fury, Galvanized Aptitude). This type is an additive recalculation of all effects, but omits +X% Damage in the recalculation, thus making CO mathematically additive to +X% Damage. However, this recalculation inadvertently omits some other effects. This is the most common way on how COlike effects stack with damage bonuses.
 (Base Weapon Damage × Most Damage Bonuses × Other Damage Multipliers) + (Base Weapon Damage × CO )
 Or Base Weapon Damage × [ (Most Damage Bonuses × Other Damage Multipliers) + CO ]
 Damage multipliers or effects that are ignored with Additive Stacking COlike bonuses:
 Damage Falloff (conditional damage multiplier)
 Eclipse (conditional damage multiplier)
 Longbow Sharpshot (conditional damage multiplier)
 Additive base damage provided by all Incarnon Genesis Adaptors (conditional damage bonus, differs from weapon variant to variant)
 Some Melee Stance Multipliers, on inputs with multiple hits.
 Some natural weapon stats modifiers, such as Bow charging and more.
 (Base Weapon Damage × Most Damage Bonuses × Other Damage Multipliers) + (Base Weapon Damage × CO )
What Counts As A Status Effect?[]
All Status Effects that have a damage type equivalent are counted for purposes of calculating the CO damage bonus. For thoroughness, this includes:
 Status effects from physical damage types
 Status effects from elemental damage types (single and combined types)
 Status effects from unique damage types
 Unique "hidden" status effects
PreUpdate 31.1 (20220209) COBonuses Acting On Hidden Damage Values (Why Projectile Weapons Deviate)[]
 Main article: Weapons#Internal Mechanics
Prior to Update 31.1 (20220209), "a previous change had [CObonuses] operate relative to "base damage" but the code was incorrectly getting base damage from the impact behavior rather than the projectile." To understand why this was the case, we need to know how attacks are stored in WARFRAME's data. Projectile weapons can have their "impact:LotusWeaponImpactBehavior".AttackData
damage impact attack data overrided by the "fire:LotusWeaponProjectileFireBehavior".projectileType.AttackData
projectile fire attack data which will give the numbers as presented in the Arsenal. For some reason, CObonuses apply to values in the overrided "fire:LotusWeaponProjectileFireBehavior".projectileType.AttackData
object, causing discrepancies in damage calculations.
In most cases, hitscan attacks will have CObonuses apply as expected because their damage values are only stored in "impact:LotusWeaponImpactBehavior".AttackData
for the respective attack. However, projectile attacks may have unexpected damage calculation deviations because of this overriding behavior of the original "impact:LotusWeaponImpactBehavior"
.
Case Study[]
To demonstrate, in the case of Astilla, as of 04:46, 12 January 2024 (UTC) it's attacks are the stored as the following^{[5]}:

}
} ]
As you can see, Astilla has a base damage of 70 Impact on direct impact as defined in "fire:LotusWeaponProjectileFireBehavior".projectileType.AttackData
, this matches the ingame arsenal value as of 04:46, 12 January 2024 (UTC):
"projectileType": {
"AttackData": {
"Amount": 70,
"DT_IMPACT": 1,
"DT_PUNCTURE": 0,
"DT_SLASH": 0,
"HitType": "DHT_PROJECTILE",
"ProcChance": 0.33
},
"BounceOnAvatars": 0,
"CriticalChance": 0.17,
"CriticalMultiplier": 1.9,
"DamageRadius": 2.4,
"DealDamageThroughImpactBehavior": 1,
"EmbedDeathAttack": {
"Amount": 100,
"DT_IMPACT": 0,
"DT_PUNCTURE": 0.22,
"DT_SLASH": 0.78,
"ProcChance": 0.22,
"Type": "DT_PHYSICAL"
},
"EmbedTime": [0.02, 0.02],
"ExplodeOnImpact": 1,
"ExplosionFallOff": 0.3,
"ExplosiveAttack": {
"Amount": 120,
"DT_IMPACT": 0,
"DT_PUNCTURE": 0.35,
"DT_SLASH": 0.65,
"ProcChance": 0.33,
"Type": "DT_PHYSICAL"
},
"MaxBounces": 1,
"SweepRadius": 0.5
}
However, it also has an additional 3 Corrosive damage with DHT_NONE HitType
defined in "impact:LotusWeaponImpactBehavior".AttackData
. This damage value is not present in the arsenal nor will it apply during missions unless Astilla has Galvanized Savvy bonuses active:
"AttackData": {
"Amount": 3,
"HitType": "DHT_NONE",
"ProcChance": 0.3,
"Type": "DT_CORROSIVE",
"UseNewFormat": 0
},
"PlayerDamageMultiplier": 1,
"PvpDamageMultiplier": 1,
"criticalHitChance": 0,
"criticalHitDamageMultiplier": 2,
"radius": 0
This means that in the case of Astilla, Galvanized Savvy will have a 4.29% relative damage scaling on 3 Corrosive damage instead of fully applying 100% of its damage bonus to the actual base 70 Impact damage value (3 / 70 = 0.0429). At max Galvanized Savvy stacks of +80% damage bonus, we will see:
 70 + 3 * (1 + 80%) = 75.4 total damage instead of
 70 * (1 + 80%) = 126 total damage
 which means the player only deals 60% of the expected damage!
This since has been fixed in Update 31.1 (20220209), but other CObonus issues still exist.
Attack Catalog[]
This section contains communitysourced^{[6]}^{[7]}^{[8]} info on whether CObonuses applies to an attack additively ("intended") or multiplicatively ("not intended") and what CO counts for base damage, which is not always the same damage as the base attack.
A pattern to note is that projectilebased attacks tend to have CObonuses apply to them multiplicatively instead of additively. Nonprojectile or hitscan weapons will have CObonuses apply to them additively as "intended".

Patch History[]
Unofficial / wikiclarified notes written in (round brackets).
Update 31.5 (20220427), Update 31.2 (20220316),
 (Fixed the innate damage bonus of Kuva/Tenet projectile weapons not applying the bonus damage from CO).
 (This interaction was never broken on multiplicative cases, only the additive recalculation.)
Hotfix 31.1.7 (20220223)
 (Fixed progenitor bonus on Lich Hitscan and Melee not applying to CO).
Hotfix 31.1.6 (20220217)
 (Fixed Multishot on weapons multiplying bonus from CO by each pellet).
Update 31.1 (20220209)
 (Fixed CO on many projectile attacks. Previously, many projectiles had a default CO damage of 10 instead of using the full projectile damage. Most cases were fixed, but multistage damage and charged attacks were not).
 A previous change had them operate relative to "base damage" but the code was incorrectly getting base damage from the impact behavior rather than the projectile. This problem was pervasive and there are hundreds of weapons in our game! Please be patient and send updated reports if something slipped through our net.
Update 30.9 (20211111)
 Changed the description of Galvanized Aptitude to better reflect its current function [which clarifies that area of effect damage is not included]
 ... BUT WAIT! We want to explain why because it’s very important to us that everyone understands where we are coming from with our current design mindset. AoE Weapons are the dominant ones by every usage metric. We see this day after day. Having this bonus apply to the AoE instance felt dangerously close to a myopic choice concerning powering up player Arsenals that simply do not need it. This mod never worked on AoE, and the description now explains that to avoid confusion. We understand those seeking a different outcome will disagree with this choice, but ultimately we are not willing to further bolster AoE at this time. This is due to the increasing difficulty in creating content that serves to challenge the Tenno.
 (CO Never applied to explosions, but a handful of explosive weapons were exceedingly effective and almost exclusively used in missions at the time, so the choice was made to keep CO as a bonus exclusive to singletarget attacks to encourage their usage.)
Hotfix 30.5.5 (20210729)
 Fixed Galvanized Mods offering increased damage from Status on target not reliably working on numerous weapons.
 (Fixed a handful of reported cases).
Update 30.5 (20210706)
 Galvanized Aptitude, Galvanized Savvy, and Galvanized Shot Introduced (Making CO available to Guns for the first time).
Update 26.0 (20191031)
 Condition Overload mod Reworked. (Did not apply to explosions, such as Glaives).
Update 19.2 (20161201)
 Condition Overload mod introduced, the first occurrence of CObonuses.
