Riven Mods

“You're not supposed to be in here! You're going to ruin the surprise!” The following section contains spoilers.

Riven Mods are special mods for primary weapons, secondary weapons, melee weapons, archguns, and sentinel weapons, the latter being unobtainable as of Update 24.0.

Riven Mods are completely unique; no two are the same, even if they have the same attributes, as their numbers will differ.

PropertiesEdit

Riven mods are unique amongst other mods in a variety of ways:

• Require the player to complete stated challenge to reveal its weapon assignment and attributes.
• Carry two or three different bonuses.
• Can carry a negative stat, whose effects can be crippling but greatly increases the potency of bonuses.
• Can have any of the Madurai, Naramon, or Vazarin polarities, regardless of its attributes.
• Have their own Mastery Rank requirement independent of the weapon, ranging from 8 to 16.
• Can have its attributes rerolled with the use of Kuva.
• Are assigned to a single weapon per Riven mod, likened to Weapon Augment Mods.
• Cannot be equipped alongside another Riven mod.

Upgrade costs and Trading Credit taxes of Riven mods are equivalent to those of Rare mods.

Players start off with 15 inventory slots for Riven mods, which can be increased by purchasing 3 slots for ‍60 at a time, up to a maximum of 90 slots (total cost for all 90 is ‍1,500). Receiving a Riven mod while being at the current limit will block access to any further Sorties, and the player will be given a choice to purchase slots, trade away a Riven mod, or dissolve a Riven mod of their selection.

AcquisitionEdit

A single Riven mod is given to players upon completion of The War Within quest. Additional Riven mods can be acquired from:

• Tactical Alerts
• Gift from the Lotus Alerts
• Archgun Rivens from Arbitration Honors
• Sorties, with various drop chances:

Weapon Type	Drop Chance
Melee	8.14%
Pistol	7.61%
Rifle	6.79%
Kitgun	2%
Zaw	2%
Shotgun	1.36%

ChallengesEdit

When a player receives a Riven mod, it is Veiled and:

• Will not take up mod capacity.
• Will not grant any bonuses or curses.
• Cannot be upgraded.
• Must be equipped on a weapon of the same class:
  • Veiled Rifle Rivens can only be equipped on non-shotgun primaries.
  • Veiled Shotgun Rivens can only be equipped on shotguns.
  • Veiled Pistol and Kitgun Rivens can only be equipped on secondaries.
  • Veiled Melee and Zaw Rivens can only be equipped on melees.

Furthermore:

• The weapon used to complete a challenge is entirely irrelevant to the resulting Riven.
• It is possible to complete the challenges using any weapon or Warframe ability, regardless of which the Riven was equipped on.
• If its conditions are met, the Riven will be revealed independently of mission success.
• Completing the challenges also gives affinity.

AttributesEdit

Rivens are distinct from regular mods in that they are inconsistent in polarity, Mastery Rank requirement, attributes, and have between two and four attributes. It is possible to have Rivens to grant a very powerful set of bonuses with a negligible curse and vice-versa (e.g. Soma Sati-critatis with a curse that reduces status duration).

Riven mods draw their names from a size pool of 30, indicated by the randomized/rerolled attributes that the new mod has. Names consist of a prefix and/or a core and suffix and follow "Prefix-CoreSuffix" or "CoreSuffix".

The 30 positive attributes are:

Effect	Prefix/Core	Suffix
Ammo Maximum	Ampi	Bin
Damage vs. Corpus	Manti	Tron
Damage vs. Grineer	Argi	Con
Damage vs. Infested	Pura	Ada
Cold Damage	Geli	Do

Slash Damage	Sci	Sus
Status Chance	Hexa	Dex
Status Duration	Deci	Des
Recoil	Zeti	Mag
Zoom	Hera	Lis

*Melee exclusive attributes.

DispositionEdit

The randomized attributes for Riven mods are affected by Disposition, a modifier provided by the system that collates the usage popularity of a given weapon across the entire player base. Disposition strength controls the range of the attributes available for each weapon. Disposition can be any value between 0.5 and 1.55, but in-game this is simplified to 5 categories:

• ●●●●● (1.31-1.55): Strong: Assigned to the most infrequently-used of weapons. Rivens with this disposition provide the greatest bonuses.
• ●●●●○ (1.11-1.3): This Disposition is assigned to less popular weapons, and Riven mods provide above-average bonuses.
• ●●●○○ (0.9-1.1): Neutral: Weapons that see average usage within the player base, resulting in an equally average range of attributes.
• ●●○○○ (0.7-0.89): Slightly more popular weapons will see a less powerful Riven mod.
• ●○○○○ (0.5-0.69): Faint: Assigned to powerful weapons that see very high usage, this Disposition creates Riven mods with the most restrained of attributes.

Disposition is shared between all variants of a single weapon. For example, the Braton shares the same disposition with its Vandal, Prime and MK1 variants.

Disposition changes every three months, aligned with every new Prime Access. If a weapon's disposition is changed, the attributes on already unveiled Rivens for the weapon will be automatically adjusted to match the new disposition.

A weapon's Disposition can be seen in the Arsenal under the Upgrade tab, but only when a riven which can be equipped to that weapon is currently owned.

Below is a list of weapons by Disposition:

While not listed in the above table, all Zaw Strikes have a disposition of 1, as well at the Gaze Kitgun Chamber. The other Chambers' dispositions are: Catchmoon (0.6), Tombfinger (0.75), and Rattleguts (0.8), all have dispositions slightly below neutral.

Cycling (Rerolling)Edit

Another unique aspect of a Riven mod's attributes is their ability to cycle (reroll) the attributes via the Cycle function in the Mods segment in the Orbiter. A Riven mod is cycled after spending Kuva, found through Kuva Siphon objectives on planets close to the Kuva Fortress or as an uncommon reward for completing Bounties.

Cycling a Riven mod affects the number of attributes, as well as the final numerical attribute, but not the current weapon designation, mod rank, polarity or Mastery Rank requirement. Dispositions belong to the weapons and not the mods, and thus a cycled riven will not have attributes outside its own range of values.

After cycling a mod, both the old version of the mod and the new version is displayed, and players can choose to keep the version they prefer.

Cycling a Riven mod starts off with 900 Kuva for the first cycle and increases on subsequent cycles of the same mod, capped at 3500 Kuva. The number of cycles is indicated by a clockwise arrow at the bottom right of the Riven mod.

Total Kuva cost to roll:

• An unrolled Riven 9 times is 16,450.
• A high-rolled Riven 9 times is 31,500.

Therefore, 15,050 Kuva can be saved by rolling an unrolled Riven instead.

TransmutationEdit

If a player has excess Rivens and are comfortable with doing away several of them, a Riven Transmuter allows them to sacrifice four Rivens in their inventory for a new, veiled Riven mod.

The Riven Transmuter is a drop acquired from the Eidolon Hydrolyst, consumes four Riven mods to transmute them into a new, veiled one. The new Riven will always be of the same type as one of the transmuted Rivens. As a consequence, if four of the same type are transmuted (e.g. only rifle Rivens), then the new mod will be of the same weapon class.

Upon transmutation, the four selected Riven mods and the Riven Transmuter will be consumed.

NotesEdit

• Riven mods are not saved in a player's Codex.
• It is possible to complete multiple Riven mod challenges within a single mission, assuming the player qualifies for them simultaneously.
• While it is possible to equip a veiled Riven mod onto Sentinel weapons, the challenge will not appear for the player.
• Typing [Riven mod] in the in-game chat and selecting the mod will let other players in the same chat channel see its bonuses.
  • Typing out the name of the actual Riven mod is an alternative way of representing the player's mod in chat.
• Base (unranked) Endo value of Riven mods is affected by the Mastery Rank requirement, weapon type, and number of cycles.
• A Riven mod's weapon is determined upon unveiling, not on drop. Therefore, a Riven mod can be obtained, saved, and unveil a weapon that did not exist when the Riven mod itself was created.
• Riven mods can be used on variants of a particular weapon, including MK1, Prime, Vandal, Wraith, Dex, Prisma, Mara, and Syndicate variants.
  • Being entirely separate weapons, Riven mods for the Mutalist Cernos and the Mutalist Quanta are not compatible with the normal Cernos or Quanta respectively, and vice versa. The same restriction applies to Dual Sidearms and Single Sidearms. Several Melee weapons such as Dex Dakra and Dakra Prime, Nikana (Prime) and Dragon Nikana are also considered separate melee weapons.
• Riven mods for Zaws are determined by the Strike.
• Riven mods will not generate for Exalted Weapons.
• If a Riven mod includes multiple elemental damage bonuses, the elements listed are applied in the reversed order.
  • This means that any other elemental damage mod installed to the left of the Riven mod will interact with the last element listed as opposed to the first element listed.
  • Placing an elemental damage mod to the right of said Riven mod instead will not affect the Riven mod's combined damage for this reason.
  • For example, if a Heat damage mod is placed to the left of a Riven mod that grants Electric and Cold damage (and thus, Magnetic damage), it will create Blast and Electric damage as opposed to Radiation and Cold damage. Putting said Heat damage mod to the right of the Riven mod will keep the Magnetic damage intact.
• As of Hotfix 19.10.1, Artax Riven mods are no longer obtainable from Sorties. Given the short 5-day period between the weapon's introduction and the hotfix and the low chance of getting a specific Riven mod, Rivens for Artax are the rarest ones in circulation.
  • As of Update 24.0, all Sentinel weapons were removed from the Riven mod generation pool. Existing Rivens remain and may be unveiled, but new Sentinel weapon Rivens can no longer be obtained.
• Currently, the lowest Mastery Rank requirement to equip a Riven mod is 8, and the highest is 16.
• The total Endo gain from dissolving a Riven mod is equal to the following formula, rounded up:
  100 × (Mastery Rank - 8) + 22.5 × 2^{Mod Rank} + 200 × Rerolls.
  • For example, the base value for an unranked, unrolled mod with a Mastery Rank requirement of 13 would be: 100 × (13 − 8) + 22.5 × 2^0 + 200 × 0 = 522.5, rounded up to 523.
• Since Hotfix 23.8.2, trading rivens only requires that the minimum mastery rank for rivens be met, which is 8.
• As of Update 24.8 veiled Arch-gun Rivens can be purchased from Arbitrations Honors for 25 Vitus Essence.
  • Arch-gun Rivens can be equipped and unveiled with Atmospheric Arch-guns.

TriviaEdit

• Riven mods feature a dynamic image, which constantly shifts between the images of the bonuses. For example, a Riven Rifle mod that affects Critical chance and Critical damage (positively or negatively) will shift between  Point Strike's image and  Vital Sense's image.
  • Interestingly, Riven mods that affect Status Chance use the images of Thunderclap, Crowd Control, Stopping Power, or Staggering Force, as opposed to  Rifle Aptitude,  Shotgun Savvy,  Sure Shot, or  Melee Prowess.
• Riven is the past participle of the Middle English verb Rive, which means "to violently tear apart".
• Taking into account the existence of 24 possible positive effects, the possibility of one negative effect, and that elemental damage and punch through cannot be negative attributes, also the fact that effects don't fall into the same category nor does order matter: there are 5,083 possible Riven mod stat combinations that have two positive effects and one or zero negative effects, and 35,673 possible Riven mod stat combinations that have three positive effects and one or zero negative effects, making a total of 40,756 different combinations for a single Rifle, Shotgun, or Pistol Riven.

BugsEdit

• If you complete the objectives of 2 different Riven Mods in the same mission they can cancel each other and not open at all, but rather reset to the state they were in before the mission started.
• If a Riven mod is unveiled while already being on the weapon it turns out to be for, it will remain on the weapon but not drain any mod points. This also allows weapons to reach negative mod point values.
