Build it for a cheap, ammo-fat status secondary that never stops shooting: 114 rounds a mag and a 10.0 fire rate mean you rarely reload mid-fight. Its 23% crit chance is the weakest part of the kit, so lean into status rather than trying to force a crit build. Skip a Lich hunt aimed specifically at it if you already have a faster-killing status secondary.
The Kuva Twin Stubbas are the akimbo Kuva variant of the standalone Stubba submachine gun. Compared to the base Stubba, they roughly double the magazine size and fire rate while pushing status chance from 13% to 31%, at the cost of a slower reload.
In 2026 the appeal is still volume of fire. A 114-round magazine at 10 shots a second lets the weapon apply status procs constantly without babysitting ammo, which suits status-stacking Warframe kits and Condition Overload style melee pairings in the same loadout.
It stays a second-tier pick because its 23% crit chance and 1.9x multiplier are both unremarkable, and its 1.0x riven disposition is average rather than generous. Players who want an akimbo Kuva secondary usually compare it against the higher-damage Kuva Twin Kohmak or single-wield Kuva options first.
How to get the Kuva Twin Stubbas
- Finish The War Within and reach Mastery Rank 5.
- Run any Grineer mission at level 20 or higher. When the lights flicker yellow, kill fast and a Kuva Larvling drops.
- Walk up to the Larvling and read the weapon it shows. If it is not the Kuva Twin Stubbas, leave it alive and run another mission.
- Mercy-kill it with the Warframe whose progenitor element you want; that frame sets the bonus element on the weapon.
- Hunt the Lich: clear its nodes for Requiem murmurs, stab it with the Requiem mods in the right order, and vanquish it in the Railjack showdown on Saturn Proxima.
- The Kuva Twin Stubbas lands in your Foundry inbox with a 25 to 60 percent bonus of that element.
Fuse a second copy with Valence Fusion to push the bonus to 60 percent and choose the element you keep. Converted Liches trade in a Clan Dojo, so a Toxin or Magnetic copy can be bought. Rank 40 with five Forma.

Riven disposition sits at 1.0x, right in the middle of the scale, so a riven gives a fair but not spectacular boost. The 31% status chance is the stat worth building around; the 23% crit chance and 1.9x multiplier are too low to carry a dedicated crit build on their own.
Builds
A status-focused hybrid build fits its profile best. Multishot and fire rate mods push more pellets and more status rolls per second, Galvanized Diffusion and Galvanized Shot convert those procs into stacking damage bonuses, and Primed Heated Charge adds a fourth damage type on top of the weapon’s Slash-heavy physical split for extra status variety.

Pistol| Mod | Why it’s here |
|---|---|
| Hornet Strike | Flat base damage mod for secondaries, up to +220% at max rank, the foundation every percentage bonus scales from. |
| Barrel Diffusion | Adds multishot, meaning more pellets fired and more chances to proc status per trigger pull. |
| Lethal Torrent | Dual stat mod adding both fire rate and multishot, stacking with Barrel Diffusion for even more status rolls per second. |
| Galvanized Diffusion | Adds multishot, and every kill stacks more multishot for a while. |
| Galvanized Shot | Adds status chance and grants a stacking direct-hit damage bonus for every status type already on the target. |
| Primed Target Cracker | Raises critical damage, so the crits that land hit harder. |
| Primed Pistol Gambit | Raises critical chance so more shots crit at all. |
| Primed Heated Charge | Dual stat mod adding Heat damage and status chance, giving the weapon a fourth proc type beyond its physical split. |
Secondary Merciless is the standard pick, stacking damage on kills up to 12 times with faster reloads. Secondary Encumber is the alternative for a status weapon: every status proc has a chance to add a second random status.

Pros and Cons
Pros
- 114-round magazine and 10.0 fire rate mean almost no reload downtime
- 31% base status chance is strong for a secondary
- Large 684 max ammo reserve supports sustained fire
- Average 1.0x riven disposition takes a riven roll well
Cons
- 23% crit chance and 1.9x multiplier are both below average for Kuva secondaries
- 2.70s reload time is slow once the deep magazine finally runs dry
- Lower damage per shot than the base Stubba before multipliers
- Not tradeable directly; only a carrying Lich can change hands
Good fit for players who want a status secondary that never stops firing and pairs cleanly with Condition Overload melee or status Warframe kits. Not the pick for anyone chasing crit numbers.
