Riven Mods Explained (2026): How to Get, Unveil, Reroll and Trade Them

Veiled to god roll in one page

Last Updated on September 11, 2026

The short answer

A Riven is a random mod locked to one weapon type, with stats that scale on that weapon’s disposition. Get a veiled one from Sorties, Nightwave, Arbitrations or Palladino, unveil it by completing its challenge, then reroll it with Kuva until the stats fit your build. Check the disposition list before you spend Kuva or platinum.

Reviewed September 10, 2026, current through Update 43.5. Dispositions come straight from the game data and refresh with each patch; the rules below are re-checked after every major update.

Table of Contents

How to get a veiled Riven

Source	What you get	Notes
Sorties	A veiled Riven of a random type	Daily, one entry on the Sortie reward table; the most common source
Nightwave	Veiled Rivens in the Cred offerings	Rotating stock; spend Nightwave Creds
Palladino (Iron Wake, Earth)	A veiled Riven for 10 Riven Slivers	Once per week
Arbitrations	Riven Slivers	Rotation rewards; ten Slivers equals one Riven at Palladino
Trading	Unveiled Rivens from other players	Trade chat, riven.market listings, in-game trade with a credit tax

Unveiling: the challenge

Equip the veiled Riven on any weapon of its type (rifle, shotgun, pistol, melee, Arch-gun).
Read the challenge in the mod description. Many carry a condition, such as staying undetected or having a Dragon Key equipped.
Complete the challenge in a mission. The Riven unveils for a random weapon of that type with random stats.
The weapon, stats, polarity and Mastery Rank requirement are all set at that moment; only the stats can be changed later.

What a roll can look like

Roll	Stat size	Read
2 positives + 1 negative	Biggest (about 1.24x)	The god-roll shape when the negative is harmless
2 positives, no negative	About 0.99x	Clean and safe, slightly smaller numbers
3 positives + 1 negative	About 0.94x	Great when all three stats matter to the build
3 positives, no negative	Smallest (about 0.75x)	Looks best on paper, rolls the smallest values

Harmless negatives (zoom, damage to a faction the weapon never fights, Impact on a Slash weapon) are what make a god roll: they buy bigger positives for free.

Rerolling with Kuva

Reroll	Kuva cost
1st	900
2nd	1,000
3rd	1,300
4th	1,600
5th	2,000
6th	2,500
7th	3,000
8th and beyond	3,500 (cap)

You see the new roll before you accept it and can keep the old one instead.
The reroll count is shown on the mod and follows it through trades.
Rerolling never changes the weapon or the polarity, only the stats.

Rules that catch people

Riven capacity starts small and grows in packs of three (platinum) up to a cap of 180; a full inventory blocks Sortie Rivens.
Each Riven carries its own Mastery Rank requirement, between 8 and 16, on top of the weapon's.
One Riven per weapon at a time.
A Riven is locked to a weapon family, not a variant: a Braton Riven fits Braton Prime, Braton Vandal and MK1-Braton, each at its own disposition.
Disposition changes after a Prime Access can shrink your roll overnight; check the list before paying platinum.
Riven trades carry a heavy credit tax; keep credits banked before you shop.

Coming September 23: stat locking and merging

Announced in Devshorts 115 and 116 (August 2026) for the Iceblade of Narin update. Final numbers land with the patch; this page updates on release day.

Stat locking: lock one stat on a Riven so rerolls cannot touch it. It uses a new resource on top of Kuva and raises the Kuva cost of each reroll.
Stat merging ("Ascend"): combine two stats into a new one that cannot roll normally, for example Cold and Heat into Blast. Once per Riven, so it is a permanent choice.
Expect the Riven market to move: locked god rolls get cheaper to make, so prices on near-perfect rolls should soften.
