Double-fist rapid-fire bursts of pain with these dual-wield variants of the Grineer submachine gun. Higher Fire Rate and Magazine Capacity.

The Kuva Twin Stubbas are the dual Kuva variant of the standalone GrnUziWeapon Stubba submachine gun, with improved status chance, accuracy, fire rate, magazine size, and ammo reserves, but with slower reload speed.

This weapon can be sold for Credits645,000.


The Kuva Twin Stubbas is obtained by vanquishing a Kuva Lich who generated with one equipped. After the Lich is vanquished it will be in the player's Foundry ready to claim.

While the weapon itself is not tradeable, a converted Kuva Lich generated with the weapon can be traded to another player. The trade is performed inside a Clan Dojo's Crimson Branch room, and the recipient must not have any active Lich. Once traded, the recipient must fight and vanquish the Lich to claim its weapon.


This weapon does primarily Slash b Slash damage.

Weapon LoadoutsEdit


  • As with all Kuva weapons, the player does not have to meet the Mastery Rank displayed to obtain this weapon. It can simply be claimed from the foundry after the Kuva Lich carrying it has been vanquished.
  • The weapon will have a prefix of the name of the Kuva Lich it was acquired from (e.g. Odizrigg Agekk Kuva Twin Stubbas).
  • The weapon's max rank caps at 40 after 5 polarizations (max rank increases by 2 per Forma added).
    • Additional polarizations can be added when the weapon reaches its new max rank at that polarization level.
    • Each additional rank also gives Mastery Rank Experience, giving 4,000 points in total.
    • Mod capacity scales with the additional ranks, and can reach a total of 80 at rank 40 with an Orokin Catalyst installed.
      • Without an Orokin Catalyst, the max is 40. Combined with the five polarized mod slots required to reach that point, an Orokin Catalyst might not be required to finish modding the Kuva Twin Stubbas.
      • After polarizing a weapon, any additional mod capacity above 30 (60 with an Orokin Catalyst) will not take effect until the weapon's rank reaches 31 and above.
  • Comes with an additional bonus damage stat, dependent on the Warframe that summoned the Lich.
