An even stronger Zarr cannon to meet the demands of Kuva Liches. With stronger explosive barrages, and long-range flak shots.

The Kuva Zarr is the Kuva variant of the Zarr.png Zarr, with drastic improvements to its critical chance, status chance, the Cannon mode's damage, fire rate, and explosion radius, and the Barrage mode's accuracy and removal of its range cap, with expense to its reload speed, ammo reserves, and the Barrage mode's damage and fire rate.


This weapon deals primarily DmgBlastSmall64.png Blast damage.


  • Cannon Mode launches cannonballs that explode in a 7 meter radius on impact with a surface or enemy, then splits into 3 smaller bomblets that rain down on the point of impact.
  • Barrage Mode fires a shotgun-like flak.
  • Very high critical chance.
  • High critical multiplier and status chance.
  • Reloads one cannonball at a time, which can be interrupted at any point, allowing for planned reloading.
    • Reload time of 0.75 seconds for each cannonball, plus 0.5 seconds to begin reload and 0.55 to end.
  • Fairly large magazine capacity of 5 rounds for an explosive-based weapon.
  • Can use the launcher-exclusive Mod TT 20px.png Adhesive Blast mod.
  • Innate three Madurai Pol.svg polarities.
  • Polarizing the weapon increases its max rank by 2, capping at rank 40 after 5 polarizations, granting the weapon additional mod capacity.
  • Comes with an additional bonus DmgImpactSmall64.png Impact, DmgFireSmall64.png Heat, DmgColdSmall64.png Cold, DmgElectricitySmall64.png Electricity, DmgToxinSmall64.png Toxin, DmgMagneticSmall64.png Magnetic, or DmgRadiationSmall64.png Radiation damage, based on the Kuva Lich's progenitor Warframe, which increases the listed base damage of the weapon by 25%-60%.


  • Cannon Mode:
    • Innate DmgBlastSmall64.png Blast damage – less effective against Ferrite Armor and Infested Sinew.
      • Damage cannot be increased with DmgPunctureSmall64.png Puncture or DmgSlashSmall64.png Slash mods.
        • Physical contact with cannonballs deals only DmgImpactSmall64.png Impact damage, while explosions themselves deal only DmgBlastSmall64.png Blast damage, therefore the explosion does not benefit from any physical damage mods.
    • Explosion and bomblets inflicts self-stagger.
    • Explosion and bomblets have linear damage falloff from 100% to 30% from central impact.
    • Projectile has travel time with arcing.
  • Small magazine size.
  • Magazine must be reloaded one at a time before reaching full capacity.
  • Extremely low ammo capacity; requires just 3 reloads to fully deplete all ammo reserves.


  • Kuva Zarr (Cannon Mode Explosion), compared to Zarr (Cannon Mode Explosion):
    • Higher base damage per projectile (673 vs. 175) (individual damage types below exclude any Progenitor bonus)
      • Higher DmgBlastSmall64.png Blast damage (673 vs. 175)
    • Higher total damage (using max +60% Progenitor bonus if applicable) (1076.8 vs. 175)
    • Higher base critical chance (25.00% vs. 17.00%)
    • Higher base status chance (31.00% vs. 29.00%)
    • Higher average damage per tap (using max +60% Progenitor bonus if applicable) (1480.6 vs. 219.62)
    • Higher burst DPS (using max +60% Progenitor bonus if applicable) (3212.90 vs. 366.77)
    • Higher sustained DPS (using max +60% Progenitor bonus if applicable) (1042.06 vs. 162.82)
    • Farther max damage falloff distance (7.0m vs. 4.0m)
    • Greater max damage reduction at ending falloff distance (70.00% vs. 50.00%)
    • Higher fire rate (2.17 vs. 1.67)
    • Larger magazine (5 vs. 3)
    • Smaller max ammo capacity (15 vs. 84)
    • Slower reload time (4.8 vs. 2.25)
    • More polarities (Madurai Pol.svgMadurai Pol.svgMadurai Pol.svg vs. Madurai Pol.svg)
    • Higher Mastery Rank required (15 vs. 7)
    • Lower disposition (●○○○○ (0.60x) vs. ●●●●○ (1.15x))


Kuva Zarr 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.


  • Though the Kuva Zarr's Barrage Mode deals less damage than the Barrage Mode of the standard Zarr, any elemental Lich bonus of at least 29% will bring the Kuva Zarr's Barrage damage above that of its counterpart.
  • Navigator130xDark.png Navigator can control both the main cannon projectile as well as the bomblets.
  • Although the Kuva Zarr uses sniper ammo, it cannot be modified with Mod TT 20px.png Sniper Ammo Mutation. Instead, it is uses Mod TT 20px.png Rifle Ammo Mutation (Mod TT 20px.png Primed). This also allows for rifle ammo pickups that provide 3 ammo each, instead of the default 60 ammo. All other ammo pickups match the mod rank of (Primed) Rifle Ammo Mutation, including sniper ammo pickups.
    • As an alternative, Mod TT 20px.png Vigilante Supplies can be equipped not only to convert all ammo types to reload the Kuva Zarr, but also grant the chance for boosting critical damage especially since the cannon has a high critical chance stat than its standard counterpart.

Kuva/Tenet Notes[]

  • For weapons obtained from vanquishing the Kuva Lich or Sister:
    • 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 Lich/Sister carrying it has been vanquished.
    • The weapon will have a prefix of the name of the Lich/Sister it was acquired from (e.g. a Kuva Kohm might be called "Odizrigg Agekk Kuva Kohm").
  • Refraining from Mercy killing a lich candidate will remove their weapon from the pool of potential lich weapons until each has been refused, but only if the mission is completed. Weapons rejected from aborted missions will remain in the current cycle.
  • For weapons obtained from Ergo Glast's shop:
    • The player must meet the Mastery Rank displayed to obtain this weapon, as it is claimed from an NPC shop rather than the foundry.
  • 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 100 Mastery Rank experience, giving 4,000 points in total at level 40.
    • 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 weapon.
      • 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.
        • Legendary Mastery Rank increases the minimum mod capacity for such weapons, without the weapon needing to be rank 31 and above. For example, Legendary 1 increases the minimum capacity to 31 (62 with an Orokin Catalyst).
  • Comes with an additional damage stat.
    • For Lich/Sister-obtained weapons this is dependent on the Warframe that summoned the Lich/Sister.
    • For Ergo Glast shop a random bonus stat will be offered for each weapon and changed every 4 days (96 hours).
    • This damage stat randomly ranges between 25%-60%. It can be upgraded up to its maximum value with Valence Fusion using another copy of the weapon.
    • This bonus stat is considered a base damage type and will be applied after all elemental mods for the purposes of elemental combinations.
  View detailed explanation about element merging  
  • Weapons with an innate primary element and a different primary element provided by the progenitor both behave as innate elements and combine with each other. They will also recombine with modded elements in the following order:
    • Mod slot 1 -> Mod slot 2 -> ... -> Mod slot 8 -> Innate DmgFireSmall64.png Heat -> Innate DmgColdSmall64.png Cold -> Innate DmgElectricitySmall64.png Electricity -> Innate DmgToxinSmall64.png Toxin

*Note that the Primed or Umbra version of a Warframe share the same element


  • GarudaIcon272.png Garuda equipped with Mod TT 20px.png Blood Forge synergizes extremely well with this cannon, as not only does she reload shots extremely fast via Bloodletting130xDark.png Bloodletting and thus greatly increasing the weapon's overall DPS, her Death's Gate passive racks up extremely fast with the massive kills or assists the cannon mode causes. She should have a ready means to recover HP quickly, however, either via deploying a nearby BloodAltar130xDark.png Blood Altar or infusing herself with SevagothIcon272.png Sevagoth's Gloom130xDark.png Gloom.
  • Running a Warframe infused with EnergizedMunitions130xDark.png Energized Munitions is also practical on this weapon, as it allows for a far greater number of shots than its otherwise limited magazine size.
  • Because the Kuva Zarr sports a fairly larger magazine capacity compared to some of its other explosive counterparts (such as the KuvaBramma.png Kuva Bramma and KuvaTonkor.png Kuva Tonkor) it can be more efficient with ammo pickups, as the other weapons would immediately consume nearby pickups after merely using a shot.
    • In this regard, it shares this ammo pickup efficiency property with the KuvaOgris.png Kuva Ogris and the TenetEnvoy.png Tenet Envoy.
    • This requires avoiding pickups while reloading, otherwise it is very wasteful, as the Kuva Zarr reloads a single shot at a time like its predecessor.


  • The Grineer text on the side of the weapon reads "BOOM".
