What the Kuva Nukor actually is
The Kuva Nukor is a Kuva Lich sidearm — a radiation-blasting pistol whose real product is not its 21 base damage but its microwave field, which the wiki states hits up to two additional targets beyond the primary. In practice that means one trigger pull lands on three enemies at once, each receiving the gun’s 50% status. That is the definition of a primer: a weapon whose job is to paint a crowd with status so something else does the killing.
Base stats
| Stat | Value |
|---|---|
| Total damage | 21 per tick (Radiation) |
| Damage type | Radiation 21 |
| Critical chance | 7% at 5× multiplier |
| Status chance | 50% |
| Fire rate | 10 ticks/sec |
| Magazine | 77 (reload ~2s) |
| Multishot | 1 |
| Mastery | MR13 |
| Riven disposition | 1.20x — dispositions are retired, so every weapon uses the same value |
| Noise | Alarming |
| Trigger | Held (beam) |
| Introduced | Update 27.1 |
The numbers that matter are 50% status and the three-target field. The 7% crit at 5× is a trap — almost never invest in crit on this gun; the multiplier is high but the chance is too low to build around.
How you acquire it
You do not buy the Kuva Nukor. A Kuva Lich spawns after you vanquish a Kuva Larvling with the Nukor emblem; once that Lich is converted or vanquished, the weapon appears in your Foundry to claim. The progenitor element on the Lich is baked into the weapon. For the full Lich loop, see the Kuva and Tenet weapons guide.
Picking a progenitor element
Because the Nukor is a primer, the element decides which combined status you spread:
- Heat — the safe universal pick; folds into Viral (vs health) or Corrosive (vs armor) and is never wasted.
- Toxin — pair with the innate Radiation for a Corrosive+Viral-style spread against fleshy and armored mixes.
- Cold — makes Viral, the common late-game health-strip combo.
Whichever you pick, the gun performs its primer job; Heat simply gives the least friction. The 5× crit is irrelevant, so do not let a “good crit” Lich tempt you.
Building it as a primer
The goal is 100% status uptime on a crowd, not damage. The loadout most players land on:
- Hornet Strike + a damage or multishot mod for the base floor.
- Barrel Diffusion + Lethal Torrent — multishot, which multiplies the already-three-target field into even more status instances.
- A 60/60 element matching your progenitor’s combo goal (e.g. Pistol Pestilence / Magnum Force class mods) so the spread is a combined status, not just Radiation.
- Anemic Agility or a fire-rate mod to keep the field active.
The point is to hit 100% status so every one of the three targets per shot procs. The mods guide covers how dual-stat (60/60) mods and multishot tiers slot together.
Where it shines
- Condition Overload melee support: the Nukor paints enemies, your melee (which gets bonus damage per unique status) deletes them. This is its most-searched use case.
- Status stacking for squads: the three-target field means you buff everyone’s damage, not just your own.
- Crowd priming in Steel Path: even when the 21 damage is nothing, the status layer is everything.
It is the wrong pick if you want a sidearm that kills on its own — for that, look at a damage-focused secondary instead.
Comparisons with other primers
- Base Nukor: hits only one target; the Kuva version’s three-target field is the entire reason to grind it.
- Atomos: also a beam sidearm with some spread, but the Nukor’s field is more reliable for priming.
- Pyrana (and Prisma): a shotgun sidearm that can primer on its full-auto spread, but the Nukor is steadier.
Pick the Kuva Nukor when your goal is “spread one combined status across a crowd as fast as possible.”
Valence Fusion and high-level usage
Like other Kuva weapons, the Nukor reaches level 40 via its valence, and Valence Fusion lets you fuse a second Kuva Nukor to raise the bonus or switch the element to the donor’s. For a primer, the bonus percentage is more valuable than a specific element, so prefer fusing for the higher number unless you need a precise combo. At high Steel Path the Nukor stays relevant precisely because status does not fall off the way flat damage does; pair it with a strong primary or melee. For ranking among secondaries, the best weapons list puts it in context, and Steel Path covers where a primer earns its slot.
A concrete primer loadout
If you want to skip the theory, here is the primer build most players land on, using mods you can name and find:
- Hornet Strike — the base damage floor (you do not care about damage, but it is free).
- Barrel Diffusion + Lethal Torrent — multishot, which multiplies the three-target field into even more status instances.
- Pistol Pestilence (60/60 Toxin) or Scorch (60/60 Heat) — adds the second element so the spread is combined, not just Radiation.
- Anemic Agility — fire rate and status chance at a damage cost you ignore on a primer.
The goal is to hit 100% status so all three targets per shot proc. The mods guide covers how dual-stat (60/60) mods and multishot tiers slot together.
Element combos by goal
- Universal: Heat + innate Radiation → a flexible spread that folds into other combos.
- Armor (Grineer): Toxin + Heat → Corrosive-heavy.
- Health (late game): Cold + Heat → Viral.
Common mistakes
- Building for damage — the Nukor’s 21 base is irrelevant; it exists to paint status.
- Chasing the 5× crit — the 7% base makes crit a trap; ignore it entirely.
- Using it as a kill weapon — pair it with a Condition Overload melee or a damage primary; on its own it will not finish enemies.
Status spread priority
When you primer a crowd, the order you apply elements changes which combined status lands first. A simple rule: put Heat or Toxin on the Nukor so the field opens with a Corrosive- or Viral-leaning base, then let your melee’s Condition Overload stack the rest. You do not need to overthink it — the Nukor’s job is to get the first proc on three enemies at once, and any combined element does that. The 50% base status means even a modest build reaches 100% on a single modded shot, so the field almost always lands.
