PROGENITOR: MAGNETIC

Magnetic is used for both DPS and Priming as it allows you to run pure single elements such as electric, heat and toxin and swap between them without it combining. Magnetic status also boosts damage against overguard and shields and can create a corresponding strong electric proc upon breaking overguard that SCALES with enemy level.

MODS

• Damage: At max stacks, [Galvanized Shot] provides +120% damage per status. Since [Kuva Nukor] can proc 4 different statuses itself (hidden microwave status doesn't seem to count for nukor itself), the total damage becomes 4x120% = 480%
• Multishot: [Galvanized Diffusion] and [Lethal Torrent] together gives +290% Multishot, Lethal torrent also provides Fire rate bonus. Multishot double dips beam status DPS making multishot the MOST important stat.
• Primary status (Electric/Heat): [Primed Heated Charge], boosts heat DoTs which can stack infinitely and refresh prior stacks, doing the bulk of damage. Primed Convulsion adds electric damage and status.
• Secondary status (Viral): [Frostbite] and [Pistol Pestilence] create viral procs which boost damage to health (up to 4.25x at 10 stacks) and boost status chance. Ice storm is optional for magazine capacity
• Crits : [Primed Target Cracker] is used to boost the high base CD, but ONLY when used in combination with a flat crit booster like Secondary Enervate, Arcane Avenger or puncture procs from Encumber. You should NOT slot Primed Pistol Gambit/Crit chance mods due to the abysmal base CC.

• Pistol Elementalist: adds multiplicative status damage and improves reload

• Exilus: Primed ammo mutation or normal ammo mutation is mandatory since [Nukor] chews through ammo

FLEXIBLE OPTIONS:

Nourish means you could swap out the viral mods.
Lethal Torrent is flexible if you have alot of external fire rate boosts.

• [Merciless Gunfight]: Adds punchthrough which greatly helps crowd clearing as it increases the overall chaining of nukor, while also providing further crit damage
• Faction: Primed expel double dips DoTs (2.4x boost) and is multiplicative to other dmg sources, but only applies to a specific faction. Use this if you want to absolutely maximise DPS while fighting one faction type.

ARCANES

• Secondary Enervate allows [Kuva Nukor] to hit orange crits to take advantage of the massive critical multiplier. The average added flat crit chance is approximately 80 to 100%.
• Secondary Fortifier is nice quality of life as it steals overguard
• Secondary Encumber is able to proc almost every single status (10 in addition to the 4 from nukor to give 1020% extra damage from galvanized shot, compared to +480% from cascadia flare).
• Cascadia flare gives +480% dmg which ramps incredibly quickly
• Cascadia Empowered gives additional 750 raw damage for every status afflicted. Since [Kuva Nukor] can afflict about 10 to 20 status per second, you can get potentially up to 15,000 raw damage per second in addition to the base beam.

ELEMENT VARIATIONS

Electric vs Heat:
Electric Status:
• Deals status damage instantly
• Double dips external headshot multipliers like deadhead (1.3x1.3=1.69x)
• Has a small AOE of up to 3m, improving crowd clearing ability
• Modded electric applies into the electric status created by magnetic status breaking Overguard/Shield
• Has bonus against Murmur

Heat Status:
• Deals status damage after 1s delay
• Stacks infinitely as each new status refreshes the duration of whole stack
• Benefits from heat inherit (inherits faction and heat damage bonuses from the first proc)
• Strips armor by up to 50% after 2s, which is equivalent to a 3.7x damage boost against armored enemies

TLDR:
• Electric is best against clearing crowds of weaker enemies or single unarmored enemies quicker
• Heat is best against bulky armored single target enemies that take a while to kill (e.g. unstripped demolyst)
