Reconfigured for maximum lethality, this powerful Arch-gun still shatters targets with explosive shells, but now reaches its peak fire-rate instantaneously.

The Kuva Grattler is the Kuva variant of the Grattler.png Grattler archgun, with higher critical chance, critical multiplier, and status chance, doubled magazine size, and doubled ammo regeneration in Archwing or Necramech combat, but sacrifices damage and some atmospheric reload speed. It no longer requires spool-up to achieve maximum fire rate, but in turn its base fire rate is slightly lower than a fully spooled normal Grattler.

Characteristics[]

This weapon does primarily DmgPunctureSmall64.png Puncture damage.

Advantages:

  • High DmgPunctureSmall64.png Puncture damage – effective against armor.
  • Very high critical chance and status chance.
  • Above average critical multiplier.
  • High accuracy.
  • Shots explode in a 9 meter radius upon impact with a surface.
    • Initial hit and explosion apply status separately.
    • Explosion does not need direct line of sight to deal damage and will penetrate walls.
  • 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%.

Disadvantages:

  • Low DmgImpactSmall64.png Impact and DmgSlashSmall64.png Slash damage – less effective against shields and health.
  • Projectiles have travel time.
  • Explosions inflict self-stagger.
  • Explosion has linear damage falloff from 100% to 30% from central impact.
  • Atmospheric:
    • Linear damage falloff from 100% to ?% from 100m to 350m target distance in atmosphere (distances are affected by Projectile Speed).
    • Projectiles have a maximum range of 350 meters.
    • Poor ammo efficiency, generating high cooldown for the Archgun Deployer for every second fired.

Comparisons:

Acquisition[]

Kuva Grattler 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.

Notes[]

  • In Atmosphere, projectiles have infinite punch-through on bodies and therefore cannot explode on enemies but must hit a surface. Can be an advantage when aiming for the best surface in a group of enemies, but a disadvantage when there is no backing surface behind a target.
  • Though the Kuva Grattler deals less damage than the standard Grattler, an elemental bonus of at least 32.3% will bring the Kuva Grattler's damage above that of its 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.

  • 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

Tips[]

  • Equipped with a Gravimag, the Kuva Grattler is an extremely powerful crowd control weapon when deployed on the ground, with its high fire rate and large (for a shell-type projectile) area-of-effect damage that affect enemies behind walls. Combined with Mod TT 20px.png Sabot Rounds, the weapon can make short work of most crowds of enemies.

Bugs[]

  • In Archwing mode the Kuva Grattler has a 2.1 critical multiplier compared to the normal Grattler's 2.0 multiplier, however in Heavy Weapon/Mech mode it has the same 2.0x critical multiplier as the Grattler.
