The Kuva Nukor is the Kuva variant of the , with improvements to its already high critical multiplier and status chance, and increased critical chance, magazine, and range, but with marginally lower damage. Its beam has also gained the ability to chain between multiple enemies.
- Innate damage – effective against Alloy Armor, Robotic, and Infested Sinew.
- Highest critical multiplier of all weapons in the game.
- Tied with uncharged and for the highest status chance of all secondaries.
- Beam can chain up to 2 nearby enemies within 9 meters from the initial target, each doing 50% of the main beam's damage.
- Enemy corpses will still allow the beam to connect to nearby enemies.
- Pinpoint accuracy.
- Consumes 0.5 ammo per tick of damage.
- 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 , , , , , , or damage, based on the Kuva Lich's progenitor Warframe, which increases the listed base damage of the weapon by 25%-60%.
- Innate damage – less effective against Shielded, Infested, and Fossilized.
- Damage ramps up from 30% to 100% over 0.6 seconds when firing. After firing stops for 0.8 seconds, the damage decays back to 30% over 2 seconds.
- Low critical chance.
- Uses the standard 210 reserve ammo capacity, giving it a low magazine-to-reserve ratio.
- Limited range of 29 meters.
- Pulsing weapon effect blocks the reticle, making it harder to make consistent headshots with the weapon shooting at moving targets.
- Kuva Nukor (Normal), compared to Nukor (Normal):
- Higher base damage per projectile (26.25 vs. 22)
- Higher total damage (26.25 vs. 22)
- Higher base critical chance (7% vs. 3%)
- Higher base critical multiplier (5x vs. 4x)
- Higher base status chance (50% vs. 29%)
- Higher average damage per shot (using max +60% Progenitor bonus if applicable) (43.01 vs. 23.98)
- Higher burst DPS (using max +60% Progenitor bonus if applicable) (430.08 vs. 239.8)
- Higher sustained DPS (using max +60% Progenitor bonus if applicable) (341.4 vs. 199.83)
- Larger magazine (77 round(s) vs. 50 round(s))
- Higher Mastery Rank required (13 vs. 4)
- Lower disposition (0.5 vs. 1.45)
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.
- The Kuva Nukor can proc an invisible Status Effect called Microwave that causes the part of the enemy hit to become larger.
- Upon striking an enemy, the beam chains up to 2 enemies within 9 meters of the main target. Each chain beam does 50% of the main beam's damage.
- Headshotting the original target does not affect the chain damage.
- The beam will not chain to a Nullifier through its shield should it connect with a target outside or partially enclosed by it.
- The beam can also continue to chain to enemies even if targeting a dead enemy or an enemy who is dead but in a dying animation.
- Compared to its Tenet counterpart, the , that chains within 7 meters at 60% of its main damage, the Kuva Nukor generally deals less damage albeit at a longer range. But this is not considering the critical stat differences between the two weapons, as while the former got a far higher critical chance stat (20% against 7%), the latter has a far superior critical multiplier stat (1.8x against 5x).
- Punch Through will cause the main beam to chain independently from each additional target hit, potentially doubling or tripling the total damage output when fired into a crowd. The chain from the target hit after the Punch Through can deal damage to the first target, and vice versa. 
- The beam can damage Rampart from the front.
- As with all Kuva and Tenet 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 or 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. Odizrigg Agekk Kuva Kohm).
- 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, dependent on the Warframe that summoned the Lich/Sister.
- This damage stat ranges between 25%-60%, and is randomly generated by the Lich/Sister. It can be brought up to its maximum value with Valence Fusion using another copy of the weapon.
- This bonus stat is considered a base damage type that is added after all elemental mods.
- If the weapon innately has a primary element type ( , , , ) AND has a different primary element as its bonus stat, the elements on the weapon will combine in a unique way: Whichever of the two primary elements comes first in this element order - > > > , or "HCET" for short - will be placed second to last in the element combine order, while the other primary element will be placed last in the combine order. This order can be subsequently shifted based on the order of the equipped mods.
- For example, if the weapon innately has , using an progenitor Warframe to add base damage to the weapon will change the weapon's base element to .
- Because comes before in the HCET element order, will be placed second to last in the element combine order, and will be placed last.
- If the weapon is then modded with only , the elements will be arranged in the order , , , resulting in the weapon having + . If the weapon is instead modded with only , the elements will be arranged in the order , , , which will create + .
- If modded with and , the will be moved earlier in the combine order due to now being a modded element, so the new combine order will be , , , resulting in + . If modded with and , the combine order will be , , , , resulting in + .
